Backpack Buying Guide

Backpacker brings the outdoors straight to the reader's doorstep, inspiring and enabling them to go more places and enjoy nature more often. The authority on active adventure, Backpacker is the world's first GPS-enabled magazine and website, and the only outdoor media whose editors personally test the hiking trails, camping gear, and survival tips they publish. Backpacker's Editors' Choice Awards, an industry honor recognizing design, feature, and product innovation, has become the gold standard against which all other outdoor-industry awards are measured. And the magazine recently launched mobile media applications that allow users to text-message hiking maps and directions to their phones. In 2008, Backpacker won the magazine industry's highest honor, the National Magazine Award for General Excellence and in 2009, followed the win with three more National Magazine Awards: General Excellence Online, Personal Service Online, and best Essay.











Backpack Types










Backpacks fall into three basic categories:
  • Daypacks
  • Internal frame packs
  • External frame packs
Daypacks
These packs are used for single-day hikes, climbs, runs or bike rides. In general, daypacks are soft-backed or frameless. Daypacks are lightweight and intended for light loads (10 to 15 pounds). Good daypacks have hipbelts to prevent the load from thumping on your back with each stride.

Internal Frame PacksThese packs are used for bigger, heavier loads (15 pounds and up). Frames--either aluminum stays, plastic framesheets, curved Delrin rods, or combinations of those things--are located within the packbag (as opposed to external frames; see below), and when properly fit, they hug the contours of your back, thereby cinching the load in close to your spine.

The main job of the frame is to facilitate weight transfer to the hip area, which is where we humans are most capable of bearing it. So a good, supportive hipbelt is also critical.

Because internal frames are generally narrower and closer fitting (than externals), they're the best choice for any sort of dynamic activities like climbing, skiing, or bushwhacking, where you need good arm clearance and a tight center of balance. If you typically hike in hot weather, look for an internal with a "trampoline style" back, which means that breathable mesh is suspended across the frame to allow air circulation without any major loss of stability.

Proper loading of an internal frame pack is key, not only in order to keep the weight well balanced and stable, but also to keep you well organized.

Backpacker Tip: Loading an Internal Frame Backpack

  • Pop your sleeping bag (packed in a waterproof stuffsack or sturdy garbage bag) crosswise in the bottom of the pack. You won't need it until the end of the day and it provides a nice, stable base for your pack.
  • Next, load heavy items like your food bag, tent (poles can be removed and strapped to the side of the pack), and your copy of War and Peace. Keeping heavy objects low and close to spine will help you maintain the best balance on the trail.
  • Stuff your puffy jacket and raingear down the sides of the pack, taking up the space left by the bulkier items. (Keep the rest of your clothes in a small stuffsack, and load that in next.)
  • Use the top lid and other external pockets to stash items that you'll use during the day: snacks, maps, sunscreen, headlamp, and water treatment.
External Frame Backpacks
Also used for big, heavy loads, these packs are best for walking on trails (as opposed to skiing, climbing or bushwhacking). That's because the packbag is hung off a simple exterior frame, so the load is positioned farther away from your back. And though this might result in a wobble-fest for climbers or skiers, trail walkers who carry big loads often love them. (Tip: Use hiking poles for stability.)

External frame packs have a higher center of gravity than internal frame packs, which has two advantages: It gives excellent weight transfer to the hips and it allows you to walk with a more upright posture (with big internals you have to lean forward to counterbalance the load). Plus, they offer lots of airflow between the pack and your back, great for long, sweaty days on the Appalachian Trail or anywhere that heat is a factor.

Externals are known for their plentiful pockets and ultimate trail-livability, but there are still a few tricks to loading them.

Backpacker Tip: Loading an External Frame Backpack

  • Most externals assume that you'll strap your sleeping bag outside and under the packbag. That's why it's absolutely critical that you store your bag in a completely waterproof stuffsack. (Tip: External frame-pack wearers are rolling the dice if they rely on garbage bags for water protection. Walk too close to a branch and you're sleeping on a sponge. Spend a few extra bucks and get a waterproof sack with a roll-top closure.)
  • Heavier gear (like your food and tent) belong higher up on the frame, but still close to your spine.
  • Use any available side or front pockets to organize your gear. This allows you to skip the stuffsacks and save a few ounces.










Getting the Right Fit










Daypacks
Fitting a daypack is pretty straightforward, which is why many of them come in only one size. The shoulder straps should wrap comfortably around your shoulders, without pinching or digging under your armpits, and the hipbelt (usually just a length of webbing) should snug the bottom of the pack against your lumbar region to eliminate sway or thumping as you walk.

Multi-Day External and Internal Frame Packs
With bigger internal and external frame packs, fit is a key issue the most important one you'll face. Fit is all about the "suspension system," which is the part of the pack responsible for bearing the weight and connecting it to your body: the shoulder straps, the hipbelt, the frame, the back padding, and the lumbar area. There are three types of suspension systems:

  • Fixed Suspensions: Although they have no adjustability, fixed suspensions often come in a variety of torso lengths to accommodate different sized people. The main advantage of a fixed suspension is that, with fewer moving parts, there's a very solid connection between the wearer and the pack, which translates to stability. Downside: Make sure the pack fits you perfectly, because there's no wiggle room.
  • Adjustable Suspensions: This system has a shoulder yoke that moves up or down a track in the center of the back panel. This lets you shorten or lengthen the space between the shoulders and hips to fit a wide variety of body types. It also gives you the ability to change the way your pack fits if you develop sore spots.
  • Interchangeable Suspensions: This system has perhaps the best of both worlds. Some companies offer the ability to customize a pack by buying different size hipbelts and shoulder straps. This works particularly well for people who fall outside the range of average height and weight.
Backpacker Tip: Measure Your Torso
Before you even start shopping, determine your torso length, so you can find the proper size pack for your body. Nothing is more important in fitting a large-capacity backpack because without the proper measurement, your shoulders, back and hips will not bear the load correctly, causing discomfort and, potentially, injury. To do this, you'll need a friend and a soft tape measure or a length of string. Follow these three steps:

  • Tilt your chin down so that the C7 vertebra at the base of your neck protrudes. This is the starting point of your measurement.
  • Put your hands on your hips and use your thumbs to feel for the top of the iliac crest. Draw an imaginary line between your thumbs. Where this line intersects your spine is the end point of your measurement.
  • Have your friend drape the string or tape measure along the contours of your spine between the two points. You now have your torso length. (Most adults have torso lengths that fall between 16 and 22 inches.)
A Note on Women's Packs
These aren't just smaller men's packs in pretty colors. Good women's packs have subtle but important fit differences that can really improve comfort for women: shoulder straps that are closer together, thinner, and more tapered to meld with narrower shoulders, and hipbelts that are canted to better cup women's hips.










Capacity










What size pack do you really need? Get a pack that's too big and you'll be sure to fill it with non-essential junk and end up tired and sore. But go too small, and you might not be able to fit the stuff you do need, like safety gear.

Backpack sizes are listed either in cubic inches or liters, which can make comparison-shopping a bit tricky, especially for online shoppers who aren't able to actually see the packs before they buy. That's why we've done the conversions and broken it all down for you. The below lists are very general rules of thumb, and will depend on the sizes of the items you're packing, of course.

Tent Types
Tents fall into five basic categories:

* Summer/Screen
* Three-Season
* Convertible
* Mountaineering/Winter
* Tarp

Summer/Screen
These tents are designed for maximum ventilation and bug protection in steamy summer months. Good ones--with strong skeletal systems and full-coverage rain flies--can handle weather from moderate breezes to summer thunderstorms. Summer tents feature large swaths of mesh (as opposed to nylon), so when you peel back the fly, air flows freely through the shelter.

Three-Season
Aimed at keeping you dry and cozy in any conditions, from spring through fall, three-season tents are structured to handle strong winds (but not snow loads), and the walls are made from a combination of mesh and ventilation, which strikes a good balance between ventilation and protection.

Convertible
This type of shelter is aimed at campers who dabble in all types of conditions. It's a hybrid design that features pole, vestibule, and rainfly options that allow you to strip it down for summer trips or fortify it for stormy adventures. Walls often feature mesh windows with solid nylon panels that can be zipped close when weather hits. The tradeoff for all that versatility is weight. These tents are typically heavier than other options.

Mountaineering/Winter
With tough fabrics, sturdy pole structures, and plentiful external guy-out points (loops affixed at various key points on the tent's fly), these tents are built for the harshest conditions. They typically have low, boulder-like shapes to help shed wind, and large vestibules for gear storage.

Tarp
Geared toward ultralighters who will sacrifice anything to save weight, a tarp is one solid sheet of nylon or polyester that can be rigged to trees, roots, boulders or trekking poles. Good knot-tying skills are essential to get the most out of this type of shelter and since there are no walls or floor and bug protection is sacrificed, but if rigged properly, tarps can be surprisingly weather-resistant.

Backpacker Tips: Selecting the Right Tent
When shopping for a tent, you'll find a ton of specs and numbers, which can be confusing and often misleading if you don't know how to analyze them. Here, our checklist for getting the most out of your money.

* Floor Space: When looking at floor space, check the dimensions, not just the square footage. Tall guys need a longer layout; stout hikers need more elbow room.

* Headroom: Total headroom will be dictated by wall slope ("hubbed" or short "eyebrow" poles often mean steeper sidewalls and better living space). Think about how many people you'll be camping with and what kind of weather you might be dealing with. Think you might be tent-bound for days in bad weather? Tents with consistent headroom from end to end are great for foul weather card games. Concerned about weight? Ultralight designs--often low ceilinged or sloped at the foot--are better for sleeping than sitting.

* Shape: Aside from the square footage of your tent's vestibule, consider the shape. High-roofed rectangular designs offer more dry storage and a safe place to cook in wind and rain. See more on shape below.


Tent Shapes
Tents come in several configurations; each shape has pros and cons.

A-frame
Simple, light, and often inexpensive, A-frame designs have sloping walls, which can limit head and elbow room. Because their broad sidewalls can get battered in high winds, A-frames are best for benign conditions.

Modified A-frame
This type of tent uses a center hoop pole, a ridgeline pole, or curved sidewalls to create more interior space and structural stability than standard A-frames.

Dome
Domes come in many shapes, sizes, and pole configurations, but typically feature arched ceilings, have good stability in wind, and good interior space.

Hoop/Tunnel
Hoop, tunnel, or tube tents offer a good combination of weight and weather-resistance but they are not freestanding, which means they require adequate staking to achieve their shape (see the Features section below).

Pyramid/Teepee
These shelters consist of a rainfly supported by a vertical center pole and are staked out to form a teepee shape. Space to weight ratio is excellent, but the floorless design means compromised performance in wet or buggy weather.

Wedge
Higher at the head end and lower towards the foot, wedge tents are aerodynamic (pitched low end into the wind) and lightweight. The tradeoff is that interior space is sacrificed, especially headroom.

Backpacker Tips: Get to Know Your Tent

* Set Up Your Tent at Home: Don't wait for your first trip to set up your new tent. Set up can sometimes be tricky until you become familiar with the way the poles fit together and connect to the tent body, and the last thing you want is to be fumbling around by headlamp with rain and wind howling in your face. Go through a few dry runs at home, so set-up becomes second nature.
* Seal the Seams: Make sure all the seams on your rainfly and tent floor are taped by the manufacturer. If not, you'll want to apply seam sealer to prevent water from creeping into the stitch holes.
* Stakes? Check: Makes sure that you have plenty of stakes (plus a few extra) so that you're able to secure all stake-out loops and guy-out points when bad weather hits. (The more stakes you use, the tauter the pitch, and a taut tent equals good weather protection.)
* Know Your Guy-Outs: Especially for convertible and mountain tents, identify all the guy-out loops on the outside of the fly and pre-attach guylines to each of these points. (Again, remember: this is not something you want to be fumbling with in dark, nasty conditions.) Guylines can dramatically increase the stability of the tent in big winds.
* Pad It: Consider making a ground cloth or footprint for your tent; it will protect the floor from abrasion. Dupont Tyvek material (available at most big home improvement stores) is a rugged, light, and cheap material. Just place your erected tent on top of a sheet, trace it with a marker, then cut a few inches inside the line. (Bonus Tip: You want the ground cloth slightly smaller than the tent's actual footprint to prevent water from channeling underneath.)


Tent Features
Here's the lowdown on the most common features you'll find on tents.

Structure: Freestanding vs. Non-Freestanding
Freestanding
Freestanding tents can be erected without the use of stakes, which makes them easier to pitch and move around camp to find the perfect flat spot. (Note: All tents should be staked down to prevent them from blowing away, and to achieve maximum performance.)

Non-Freestanding
These tents rely on stakes to create the structure, so pitching in sand and snow requires special attention. They're typically lighter than freestanding tents and can often fit into tight spots.

Doors: One vs. Two
One
A tents with just one door is lighter than a double-door tent, but unless it's positioned at one of the ends, one person will be crawling over the other to get in and out of the tent.

Two
Two doors really boost the comfort/livability factor of a tent, especially when each door is protected by its own vestibule; this allows each camper to have their own storage space.

Pole Material: Fiberglass vs. Aluminum vs. Carbon Fiber
Fiberglass
These are found on inexpensive, light-duty tents. Compared to the other two types, they are cheaper, heavier, and less durable.

Aluminum
The vast majority of good backpacking tents use aluminum poles, which are strong, light, and easy to replace.

Carbon Fiber
Found on ultra-high-end tents, these are super-light and super-strong, but not as durable as aluminum. They're also more expensive.

Pole Connection: Sleeves vs. Clips
Sleeves
When poles feed into continuous sleeves along the tent body, a very solid structure is created that is best equipped to handle wind. But, setup can take longer and airflow between the tent body and the fly is impeded, so condensation can become an issue without proper ventilation.

Clips
Setup is fast and easy with plastic clips that attach tent to poles. Airflow is superior, but stability in high winds is sacrificed.

Wall Construction: Double vs. Single
Double-Wall
A traditional double-wall tent uses an inner canopy (to sleep in) and a rainfly (to keep water out). Double-walls tend to be less expensive, drier in wet conditions, and have better ventilation.

Single-Wall
Single-walls use one layer of waterproof/breathable fabric, which makes them lighter and often easier to set up. Condensation can be a problem, so look for vents or a hybrid design (that uses a partial rainfly, often over the front door) to help reduce condensation.

* Ceiling loops are great for hanging lanterns or lines for drying socks and clothes.
* Metal pole junctures called hubs add sturdiness and allow poles of different lengths to join. This cuts weight and helps pull the canopy outward to create vertical walls and more living space.
* Store small items (headlamp, ipod) in the tent's inner pockets.
* Guylines provide extra stability in wind, rain, and snow. Attach them to guy-out loops, located along the perimeter and at key seams on the rainfly. Tip: Use reflective cords to avoid tripping in darkness.
* Found on double-wall tents only, the inner canopy (breathable and often made of mesh) lets moist air escape rather than condense in the tent. It also keeps bugs out.
* The rainfly--usually nylon and coated with polyurethane or silicon--should cover the tent body with a few inches of space remaining between it and the canopy to allow airflow. Some tents pitch in "fast-pack mode," using just the fly and poles, to shave weight for trips in mild, bug-free conditions.
* Poles create the tent's skeleton. Treat them with care: Never snap poles together (the ends can splinter), and when breaking them down, start in the middle to minimize tension on the shock cord.
* A waterproof bathtub floor curves a few inches up the tent's sidewalls to prevent leaks in rainy weather. Ideally, the rainfly should overlap the floor's perimeter by several inches.
