55L PACK, IDEAL FOR
- Long Distance Backpacking & Thru Hiking
- Any Environment
Become UNBOUND to go bigger for longer! The UNBOUND 55 expands your capacity for more adventurous trips by adding extra volume to accommodate seasonal clothing and gear changes, or more food and water when resupply points are fewer or farther in-between. 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 55 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 55 carry some of the weight.

Product Reviews and Questions
Unbound 55
Walked the AT last year and wanted a Hyperlight rucksack
Now I have the perfect size for future thru hikes
I love this!
So, I'm not a thru-hiker... yet. But, I've been hiking over 20 years with mainly Osprey bags (which I still love). However, I just got my feet wet with the more UL gear that's out there, this pack being one of them. And this Unbound 55 carries all the gear very comfortably! Surprisingly comfortable! All the straps are narrower than what I'm used to, but still feels great! I'm starting the Long Trail soon to prep for my AT thru next spring. And this is the bag of choice. I've now put 20 miles on this bags since I got it a couple days ago. I have no doubts on this bag carrying my gear for my upcoming long distance hikes! Nice work HMG!
Unbound in the 100 mile wilderness, Maine
Pack held up through rain for 8 days heavy rain with no issues. The front pockets around the waist belt aren’t water resistant. Overall the pack is awesome… obviously light wait but also ran into no issues carrying 8 days of food and gear (roughly 20-25 lbs) through remote wilderness and had no issues with straps, buckles etc. the frameless design is awesome. Would definitely recommend for any thru hiking.
Review from a new to ultralight hiker
Long time hiker and "force marcher", which is military for "hiking". With the exception of the pack I had in the military, I've always used frame packs with lots of padding and support structure and been fearful of the ultralight packs because they might be as uncomfortable as my frameless military pack. Since my wife and I decided to hike the AT next year and I started looking at weights, I took a chance after a lot of research and review and ordered this pack. The site showed 1 to 2 weeks lead time. Well, it shipped two days later which made my day!! I received the pack a couple days later, unboxed and inspected it. It's built very well and sturdy. Not a stitch out of place. Packed it with 15lbs and took off on a shake down. The pack actually fits me better than the pack I already had. After a bit of adjusting, I got it settled and was surprised at how well it fit and felt. No rubs, raw spots, soreness or issues. Since then, I've put about 40 miles on it with ~20lbs in it and it's still out performing my framed pack. No issues so far. Haven't been rained on so don't know about weather resistance yet, but can update later once I know. To sum up, this has so far been a very good purchase as it actually fits better than my framed pack, performs as well or better and weighs 3 pounds less. I'm very happy with this so far!!
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!
