Our preferred pack for backpacking in dense, heavily wooded trails in the roughest, toughest climates.

  • Dry, Rocky Environments
  • Backpacking & Adventure Travel
  • Continental Divide Trail
FREE SHIPPING ON ORDERS OVER $200
OUR CLOSE QUARTERS TRAIL PACK

On rugged and tight trails, the 3400 Southwest is a flexible performer that can adapt and handle the way gear volumes change for weekend, section, or thru hikes. Ideal when resupply points are less frequent and/or for equipment flexibility is needed. When the extra volume is not in use, the 3400’s top can roll down enough to make the overall size of the pack similar to the 2400, but that additional space can come in pretty handy when you need it.


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.

So Light and Comfy
I’m glad I researched and found this. It’s literally the perfect pack. It's light, comfy and massive yet compact. Hip belt pockets are the perfect size as well.

Best Gear Choice I've Made!
I bought the southwest to replace my much heavier pack. I've used this several times now and each time I marvel at how light it is, but even more how well it carries weight. Additionally, the customer service was great when I was looking at sizing. Can't wait to put a ton more miles on this thing.

All I Had Hoped For
I love my pack. Lots of expansion for big trips. It’s light and compresses for short day trips. It keeps things dry on wet trips. Looks stylish on sunny trips.

Lightweight and comfy

As a more petite person, I have a hard time finding smaller high capacity packs that do a good job of holding all my stuff and also having the things I need where I need them. So far I'm loving the Southwest and can't wait to get some more miles into it next hiking season.

Great pack! Allows puddles to form inside

I’ve used my Southwest 3400 on numerous backpacking trips, from 4 days to 40 days, and it’s held up against almost everything. It fits me really well and I appreciate the simplicity of the design. The one thing that frustrates me about it is that it’s water-resistant, not waterproof. Of course, 100% waterproofing is probably impossible, but with this pack, in the main body and in the hip belt pockets, water seeps in and then doesn’t seep out again. I’ve had some of my belongings just totally sopping wet with water because the waterproofing on this pack catches water on the inside. Wack. Definitely use a pack cover!

Awesome pack

Just used my new pack for a 13 day mountain traverse. It was great. Carried the weight well, other than dirt no signs of wear at all. I've had a lot of packs and this is the best ever.

丈夫で使い勝手の良いバックパック。

特に気に入ったのが大きなフロントポケット。あまり気にしないでサンダルや服,ゴミなどをガンガン収納できるのでとても便利です。予期しない藪漕ぎの場面に出くわしてもでもメッシュではないので,ひっかかる心配が少なく,黒にしたので汚れも目立ちにくい。早速テント泊で使いましたが,特に堅牢さを重視する自分にとって,とても満足できる製品でした。

An upgrade from every other pack I've used!

I just got back from my first backpacking trip using the 3400 Southwest and cannot say enough good things about it. It carries incredibly well and is super comfortable for long days. We encountered a downpour and the bag performed well in the rain. The minimalist style takes some getting use to, but once you figure out how to be efficient with your layout it is perfect. I highly recommend.
