DAY IN, DAY OUT. THIS IS THE PACK FOR THE LONGEST TRAILS

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.

Great Pack

So far we’re giving it four stars until we actually go on our trip. I have no pictures as of yet but I will update this review when we do. We meet the people at Hyperlite in Damascus on Trail Days and purchased their 2 Person Unbound Tent and wished we had of bought the packs then but since we have now purchased 2 Unbound backpacks and cannot wait to use them. Customer Service has been top notched so far with questions and answers. Happy Trails

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!
