SKU: 3-10840-1
40L PACK, IDEAL FOR
- Long Distance Backpacking & Thru Hiking
- Any Environment
There is simply no better way to measure the effectiveness of a pack design than to send it out on thru hikes. Over the course of 2,000+ miles and an average of five to six months, day in, day out, loaded and unloaded, jostled and dragged, and exposed to the elements, one of these long walks is going to tell you the truth. So, that’s what we went after, and the Unbound 40 is the honest to goodness result. Every carefully considered feature fought for its right to remain, leaving only the essentials required for an efficient, comfortable, adaptable, and dependable travel companion. Thru hiking is hard enough. Let the Unbound 40 carry some of the weight.

Product Reviews and Questions
Great updates in comparison to the SW 3400
I took the SW 3400 on the PCT and CDT and absolutely loved that pack but needed a new one. From what I can tell in the early use of the Unbound 55, all the differences in design are nothing but positives and it carries as comfortably as my SW did. Smart changes HMG!

Customer service is excellent!!
Unbound 40
Great pack. Used it this week on the AT. I wish the chest strap was adjustable. I would like it lower. It looks like you can’t undo the clips and strap to move it down to another position on the shoulder straps. But. Great pack, great design. I really enjoyed it this week and look forward to using it many more times. Thank you
Awesome redesign
This pack has everything I have always wanted without going to competitors for extra features. Now a solo hiker my partner of 55 yrs has died. We always split the weight but now it’s up to me. Me and my dog, Alice will continue on in John’s memory
Absolutely love it
Great pack that carries the weight well.
The front mesh reachable from both ends is a gamechanger, super convenient to reach equipment like a rain jacket from the bottom as that is where I keep it.
Only little annoyance, water bottle is hard to reach and put back with one hand as it's very secured in the extra high side pocket.
