OUR CLOSE QUARTERS TRAIL PACK
The Southwest 40 keeps you honest about packing smart and efficiently on weekend or section hikes where the supplies you may need to replace along the way are never too far out of reach.
When the route is thick with vegetation, requires the occasional up and over immovable objects, and calls for “suck in your gut and shimmy through” type moves, the Southwest is the backpack you want up-close and personal. This pack family is made specifically for tough adventures that would rip most other ultralight-style packs to shreds.

Product Reviews and Questions
Amazing and versatile backpack
I absolutely love this pack. It fits a lot and can carry significant weight (I sometimes had 20-25lbs) very comfortably. It's also seriously waterproof. I had it in day long deluges and week-long mist and not a single drop got in. The external pockets are useful, too, as they provide an extra 8 or so liters of storage -- enough to keep all you'll need during your walk. Again, I love this pack. I took it with me on a 2-month long trip and I'm looking forward to taking it on its next adventure!
Great for ultra light
This pack is light weight and a pleasure to use. My base weight is currently about 15 lbs. I have to carry a lot of water because the areas I hike in does not have access to water. My total weight is around 35 lbs so this pack does dig into the shoulders some at that weight. Also, there is no ventilation for your back so you will sweat… a lot. Otherwise, I am in love with this pack and highly recommend it (especially if your base weight is low and you do not need to carry large amounts of water). Would like to see load lifters and thicker padding but I know that is not what these packs are about. This pack handles light loads very well and is comfortable under that condition.
New pack
This is a new pack for me… trying to go lighter. It’s feeling great and easy to move in! Wonderful layout of pack- storage and dry capabilities!
しっかりした作りに驚いた
ULザックは初めてでしたが、心配する必要がなかった。
ショルダースタビライザーがないので後荷重になることがあり、チェストベルトも長すぎて調節が効かない。
しかし、山ではザックのカッコ良さが全て帳消しにしてくれる。
結局はザックだけでなく荷物を軽くすれば、このザックのデメリットも解消されるので一石二鳥だと考えています。
