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.

Checks a lot of boxes

As a long time owner of the HMG SW backpack I’m very fond of it after using it on my PCT Thru and many other thousands of miles. Despite my fondness I've been looking for some solutions.

The extra large water bottle pockets is one of those solutions. The Unbound 40 allows me to carry a 1.5 L and a 1 L bottle in each pocket. Thus allowing me to carry 5 liters.

Previously I would have to strapped a 2 liter CNOC bag to the top of the SW backpack. Weight up this high is awkward.

The stretchy bottom pocket is another one of those solutions allowing me to carry the day’s food and avoiding opening my bag.

Finally HMG solved the biggest headache of the SW which was the back mesh pocket. The stretchy material on the Unbound 40’s back pocket is a dream. Easy to stuff grab and use the stored contents.

The mini pocket is great for misc items such as tent stakes, wind jacket or other small items.

The hips pockets are small in size compared to other packs but as a long time Fanny pack user I just carry my medial/hygiene in one hip pocket and my electronics charging cables/outlet block in the other.

The new buckle design is great but unfortunately it leaves a long leash of fabric dangling if you are a thin hiker.

The shoulder pocket from my SW works great on this backpack.

A couple of things I wish the pack had:

1. Ice axe loop off centered.

2. A loop higher above the mesh back pocket and below the mesh for strapping a foam sleeping pad vertically.

3. A little more…

Worlds Greatest backpack

This backpack carries so well! I love the trash lunch, hip belt and gigantic water bottle pockets. The bag itself is made exceptionally well and to a super high standard. If you are in the fence about getting this backpack, get it, you won’t be disappointed!

23 miles and impressed

In the past week and a half I have been using the pack almost every other day. My wife is still slightly mad about the price…. I think she would have been convinced if it came with the water bottle and cell phone holder I ordered separately. Hahaha.

Overall it is a great pack with great features. I recommend it.

The only Cons: the back doesn’t breathe, I wish it was offered in 60 L,

HMG Unbound

Very nice pack. Once I saw it was available in black I ordered it. Lots of nice features. I love the new hip belt. I can fit my tent stakes, a center pole, headlamp and a 32 oz. Nalgene in one the water bottle pockets

Love it. Mostly.

The new hip belt, bigger side pockets, and side straps are great improvements over my old Junction, which I also love. I thought this was going to be my perfect pack for all my thruhiking needs. It would be perfect if they didn't remove the ice axe loop. A small critique for sure but confusing why it was not included.
