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.

Product Reviews and Questions
UNBOUND55 can be carried comfortably
I only use extreme UL backpacks that I carry only on my shoulders when the load is less than 5kg.
In the first place, if I need to carry luggage that weighs more than 15 kg, I use a traditional type backpack that can firmly support the waist load.
Even so, when I carry around 10kg of luggage, I want to reduce the weight as much as possible, so I use a UL backpack, which weighs less than 1kg and has a built-in frame that can support the waist load. Therefore, I am currently using WINDRIDER2400.
I recently purchased the UNBOUND55, which has a slightly larger capacity to carry bulky items. I was a little worried because it only has one built-in aluminum frame to save weight, but when I tried it with over 10 kg of luggage in it, I found that my shoulders hurt even if I carried it all day. I was able to confirm that I could carry it without any problems.
Naturally, I took the frame out and adjusted it to fit my back, bending it to fit snugly, just as many traditional backpacks do in the past.
I use size M, but the middle value of the back length of the pack is the size of your own back length, so when you place the hipbelt along the hipbone, the height of the shoulder belt and the shoulder are the same. They are almost the same, so when you tighten the shoulder strap, the back of UNBOUND55 can be carried tightly from the shoulder to the waist without any gaps.
It has the functions of a standard UL backpack, so I have high hopes that it will be useful in the future.
Great pack
Perfect size,big side pockets i can put my tent in one side pocket. Love the hip belt!!! Custom fit
Awesome
Amazing! Glad I fine tuned my gear or this would be to small
So excited!
Definitely the best hiking backpack out there!
Drain Holes ????
Top-Rated Pack for any adventure. Excellent is so many ways for my mountain adventures but would like to see a few things on it such as small water drain holes in the side pockets, ability to fit carbon fiber pack stays into pack, and possibly load lifters as an option. Still one awesome pack I love.
