Good upgrade

Like the big side pocket, side cord works better than Southwest, front pocket stretches at the right level.

Very happy hiker!

The Unbound 55 was nice, but when I bought the 40 it seemed like it was made for me. It carries all of my load and the shoulder straps don't rub at all.

Break in on the AZT, a solid 4.5+ stars

We're 2 weeks in on the AZT so I'm getting to know the unbound 55. I was leary of the stretch mesh and side elastic cord retention system but it's proven to be highly functional and largely secure. The cord can be restrung to different pack loops which I did to hold 1 Liter smart water bottles better. Bottles stay put unless really bending over but not sure any pack could do that consistently. The stretch mesh can take a lot of day use stuff minimizing the need to open the top most of the day. You do have to watch a bit as when the pack is less than full as the tension to hold things in the mesh is less. Nothing's dropped out but just something to watch.

The hip pockets are large and hold a days worth of snacks, chapstick and small sun block. I do feel like I have to twist my torso to see and get things out of those pockets but maybe that's because I was high in the small pack range but not quite a medium.

The strap system and harness are a bit spartan is the only critique. It synches up well and carries higher range weights ok but it's not plush.

This is a great, maybe fantastic, on the go access pack for those not ready to get super small like Nashville or palente.

Has everything you need and more..

On the AT right now and I’m loving this pack. Keeps things that need to stay dry - dry.. The two side pouches - one carrying my tent and other water/more essentials -are just that. A LOT of stretch fabric on this pack lets you stuff the rest. Do find myself tightening the waste strap during the day but not enough to be a nuisance. Overall very happy with this pack - would recommend.
