WHY CHOOSE THE UNBOUND 40?
ACCESSIBILITY ON THE MOVE
Large dual-entry front external pocket for quick grabs without needing to dig through everything inside. Generously sized side pockets and a stretch bottom pocket add even more storage options
MAKE IT YOUR OWN
Low-profile daisy chains allow countless ways to carry external items for different kinds of trips. Remove or add top-side compression straps depending on needs, or shock cord for oddly shaped gear
COMPLETE SEAM TAPING
With the exterior binding, seam bulking is eliminated within the pack, allowing for more efficient taping and improved water resistance

I was very surprised how comfortable this pack felt on my back after reading a lot of reviews about how uncomfortable the straps are. If you actually get the right size for your body then you will have no problems with shoulder soreness.
I would highly recommend that you find a local store to try one on before purchasing one if you’ve never worn a ultralight pack. These packs are for everyone, only for us who need a bare bones pack with the right amount of pockets. Not like an osprey which has too many pockets IMO.
I own a Zpacks arc blast and this pack is up there with that for comfort but that’s for my body type and experience on knowing how to pack the backpack and where it should sit on my hips.
I will be purchasing the new Junction 55 as soon as I post this.
Thank you HMG for a quality product 🫡

This is my first piece of gear from hyperlight but definitely not the last. The pack performed perfectly. I paired it with the versa fanny pack and together they made the ultimate backpacking kit. The unbound carried 28 lbs over 4 days on the Teton Crest Trail like a champ. The main compartment fit a bv450 easily along with my other gear. Side pockets were accessible while the pack was on, so it was easy to get to my water bottles. The front mesh compartment had plenty of space for my gear that was needed throughout the day . I used the mesh on the bottom of the pack for snacks and trash while hiking. At 5’5” I ordered a small frame and the fit was great. Looking forward to the next adventure with this pack.

I was worried about the fit and carry of a pack that I never tried on before, those fears were quickly erased when I took the pack out for a short multiday trip here in Alaska. The pack fit like a glove and the way the pack carried was a dream! With all of the external storage and easy access to my gear, I couldn't ask for anything more of a pack.
