HMG Unbound 40 - represents Hyperlite's vision of the perfect travel companion on the longest trails, built to make life easier and carry the weight day in and out, no matter your time away.

At weight just 853 grams (size medium), the Unbound 40 is a joy to carry. But that’s just one of the many features that make this pack so ideal for the rigors and challenges that big distance trips present. Efficiency is the key to happy hiking, and everything about the Unbound 40 encourages forward momentum.

The outer pockets have the right volume for the gear you want access to during the day, while the simple and spacious interior welcomes those big items that only need to come out at camp. Low-profile daisy chains allow exterior cargo hauling customization if you need it, and all-around seam taping provides superior protection against the elements, so you don’t have to scramble to keep your essentials dry.
