If you're looking for a large volume pack that can handle heavier loads—this is it! I was looking for a pack for long trips (week+) and for winter camping where gear is bulky and sometimes heavy. I found several packs that had adequate volume (70+ liters), but not any that stood out as far as carrying heavier loads. A couple of my buddies use Seek Outside for big game hunting and suggested looking at their lineup. I settled on their Divide pack—it had the volume I was looking for, was relatively… Full review
I would not be shopping at Gossamer. Customer service alone is a deterrent. There are much better companies to deal that are worthy of our support. The company may have good bags, but unfortunately the service is horrible. They don’t take responsibility for their products. I spent a long time trying to figure out what bag to get, and decided on the Mariposa. Tired it on via a couple of friends and did extensive research. When I received it the web strap on the belt was 1-inch, which is not what… Full review
A 19-liter lightweight packable day pack with sternum strap, three outside pockets, an internal hydration sleeve, compression straps, and half-clamshell zippered opening. Good design for minimalist everyday carry, day hiking, and accessory travel backpack and personal carry-on bag. I bought this backpack as an accessory day pack for "onebag" style travel. My main carry-on travel backpack is a Gregory Compass 30 liter and is too big for day trips. I have a 46" chest and the shoulder straps wrap… Full review
Excellent ultralight and packable 23-liter backpack for EDC, travel, and day hiking. I have owned the Gossamer Gear Type II Summit Pack and the original Vagabond backpack and was happy to see this new update on the Vagabond. There are now three versions of the Vagabond packs in production with the Packable version being the lightest and lowest priced. I do a lot of "onebag" style travel and this version stows easily in my larger carry on pack or can be used as a "personal" carry on flight bag. … Full review
Lightweight, bombproof, and well thought out. A keeper for my uses in winter and summer as well. Been through a few nice ski/board packs. All were beautiful for winter sports. The Cobra is all that and then some. Very light comparatively. Has all the bells and whistles I find necessary without the weight. I was amazed at how it hugged my body while descending some steep trails in the thick of winter. That incorporated design impressed me greatly. I wasn't psyched with the bright red color, but… Full review
Great minimalist waterproof day pack. Simple and light, very underrated! I have many pieces of Outdoor Research gear, and I have been pleased with all of them. The Outdoor Research Dry Summit Pack LT does not disappoint! Might be light on features, but it checks all of the boxes if you are looking for a minimalist pack. What I like... I have been using it for a week, both as a daypack for work and used on a 5-mile day hike, and the pack performed admirably. Even though it has no internal frame or… Full review
A bag for all adventures. I have used this bag all over the world. It's kind of a standing joke with me and my blue bag in Peru, Europe etc... I love it and for $17 at Walmart it is still my go-to bag for the last 10 years. I want another, but they are sold out...I'll keep looking. Full review
Mine was equipped for tequila shots and fits four travel size bottles of Cuervo Gold and one shot glass. Works great, lightweight and I really can’t add anything else as Goose nailed the efficiency and value of this product. Wear it responsibly!!! Full review
Forget brands like Platypus and Nalgene. The most efficient way to carry your beverages on the Appalachian Trail is the Mt Katahdin Hydration Belt. It’s the first of April, and the thru-hiking season is underway. Across the country, myriads of twenty-somethings are leaving their parents’ basements and setting out on the long trails to find the true meaning of life. And while thousands will start at Springer Mountain, Georgia, only a dedicated few will fight through the hangovers and public intoxication… Full review
How to Choose a Backpack
Like most outdoor gear, choosing the right backpack depends on how you plan to use it and selecting one that fits you, your needs, your budget, and your gear.
Capacity (or How Big?)
Consider the following questions to help determine capacity, or how big of a pack you really need.
- How long are you heading out for: a day, an overnight, a week?
- What's your outdoor style? Are you a minimalist, or deeply attached to creature comforts, or somewhere in between?
- How much and what gear will you bring for specific trips and activities? Don't forget group gear and seasonal items (for example: winter gear will take up more room).
Obviously you need a backpack that fits all your gear. If possible, lay it all out, including food and water, and be honest about what you'll need to fit in your pack.
Backpack sizing varies between individuals and manufacturers, but the following ranges are a basic starting point:
- Day Pack:
less than 2,000 cubic inches
up to 30 liters
2,000 - 2,999 cubic inches
- Weekend and Multi-Day:
3,000 - 4,499 cubic inches
- Week-Long and Expedition:
4,500+ cubic inches
74 liters and up
Pack Tip: Don't buy a backpack bigger than you need. You'll be tempted to fill it and carry more than necessary, or you'll end up with an annoying floppy, half-filled pack.
Fit (Is It Comfy?)
Types of Backpacks
Are designed for done-in-a-day hikes, runs, skis, and (for some minimalists) the occasional overnight. Daypacks may be frameless rucksacks or incorporate a stiff frame sheet or metal stay for support.
External Frame Backpacks
External frames are also available in sizes suitable for a weekend overnight to a winter camping expedition. More rigid than internal packs, externals typically carry heavy loads well.
Designed for active, endurance pursuits, hydration packs feature space for a hydration reservoir and tube for drinking on the go. Some also have space to carry gear.
Also known as lumbar packs, fanny packs, and hip packs, these small packs allow you to carry a few essentials on short outings, such as gel flasks on a run or a camera on a short hike.
There's no need to leave Junior behind when you hit the trail. Just load him or her into a kid carrier and head on out.
Font packs allow you to carry gear that you want to access immediately on your chest.
Nothing beats the expertise of a knowledgeable pack fitter. Find one at your local outdoor retailer. In the meantime, here are some additional tips to help you choose a backpack that fits you well.
Size a backpack to your torso length. Don't assume you need the tall (or the regular or the short) model based on your height. The sizes of different manufacturers' frames may correspond to different torso lengths. Check each pack's technical specifications.
To find your torso length, have someone measure from the iliac crest at the top of your hipbone to the prominent bone at the base of your neck (the seventh cervical vertebrae). (See how to properly fit a backpack in this instructional video.)
Many pack manufacturers produce women-specific or short torso versions. Women, kids, and others with short torsos can consider backpacks sized for them. On average, these fit the average woman better.
Pack Tip: Don't get stuck on a pack's gender though. Buy the one that fits you best.
Straps and Padding
Shoulder straps, which control the fit of the suspension system, should be well padded and adjustable.
An adjustable sternum strap, which connects the shoulder straps, helps bring the load weight forward and off your shoulders.
Since it supports your pack's weight, make sure the hipbelt provides adequate padding. Some pack makers offer interchangeable hipbelts in different styles and in sizes for both men and women for a better individual fit.
Fitting your gear in the pack is one thing. Making sure it rides comfortably is another. What's the typical weight of your gear? Check that it matches the manufacturer's recommendation, particularly if you're opting for an ultralight pack.
During a fitting, load the pack with weight to see how well it carries. Walk around with the loaded pack, practice taking it on and off, move around, and climb up and down stairs and slopes.
How well is the pack's load distributed? Does it remain comfortable over its carrying capacity and intended uses? Does it feel stable?
Features & Organization
Consider the pack's organization. Is equipment stowed securely? Is it easy to access? Intuitive?
If you'll be carrying any specialty gear, such as ice axes, snowshoes, skis, or a snowboard, look for a pack with features or accessories designed to hold those items, rather than trying to jury-rig them on later.
Depending on your different activities you may need more than one backpack, perhaps a large internal frame pack for multi-day backpacking trips and a small daypack for day hikes.
Find the best pack for you and your activities and you'll be ready to hit the trail.
