Review

For those seeking a lightweight and durable backpack for long-distance hiking and ultralight backpacking, the HMG Unbound 40 pack is a standout option. Now, let’s take a closer look at the various features and elements of this unique pack.

Ultralight Design: With a weight of less than two pounds, the Unbound 40 is an incredibly lightweight pack. It’s one of our top choices due to its minimal weight, which helps lessen strain on your body and allows for more efficient and longer hikes.

Water-Resistant and Durable: The Unbound 40 is made using Dyneema material, known for its natural water-resistance. In addition, the bag has taped seams to provide extra protection against water. While it’s difficult to make a completely waterproof backpack, the Unbound 40 comes close. This means you can confidently trek through rain without fear of your important items, like a sleeping bag and extra clothing, getting drenched. For even more assurance during bad weather, consider using waterproof stuff sacks in conjunction with this backpack.

Bottom Pocket: HMG joined the trend of popular cottage brands such as Pa’lante Packs and Atom Packs by adding a bottom pocket to their Unbound 40 backpack. Although this feature is relatively new in mainstream backpack design, it offers great convenience. The bottom pocket provides a convenient spot to store items like snacks, drink mixes, or gloves for easy access while on the go. No need to stop and dig through your bag during a downpour – simply reach into the bottom pocket for your rain jacket.

Overall Impression:  The Unbound 40 is a worthy contender against our trusted favorite, the HMG Southwest 40. Its design allows for efficient use, protection from weather, and low weight, making it a top choice for long-distance hikers. Whether you’re embarking on thru-hikes or ultralight adventures, the Unbound 40 delivers on both performance and functionality.

For those looking to balance saving weight with practical features on a long trek, the Hyperlite Mountain Gear Unbound 40 is an excellent option.

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, unloaded, jostled, dragged, exposed to water, sweat, sun, and dirt, one of these long walks is going to tell you the truth.

So, that’s what Hyperlight 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.
