    Styled for sandstone.

    Hike down dry river beds, bushwhack through scrub, and explore slot canyons with Hyperlite Mountain Gear's ultralight 2400 Southwest 40L Backpack storing everything you need for a minimalist overnighter. Despite its ultralight weight, the Southwest is surprisingly comfortable and durable enough for long hikes. Its Dyneema Hardline suspension system includes spacer mesh foam at the shoulder straps and waist belt, and there are supportive aluminum stays that you can remove for even less weight.

    Hyperlite Mountain Gear made this pack out of the same Dyneema rope fabric used to catch climbers when they fall, so you know it will last for seasons. The Southwest also has a roll-top closure and taped seams for reliable protection in wet weather. There's an internal sleeve styled for hydration reservoirs (not included), and a loop designed for ice axes. The Southwest also has external, snag-free pockets, zippered waist belt pockets for valuables, and top and side compression straps for a secure load.

    Love the pack!

      I was looking for a durable, lightweight, minimalistic bag. This bag is essentially a giant dyneema drybag with some well executed features transforming it into a fantastic bag.

      Impressions after using this bag for a while as a Crag bag to haul climbing gear on hikes and backpacking with it.

      * Light as a feather, non sarcastically I think if you tied a string to this bag and took the straps off you could use it as a kite.

      * Super comfortable load distribution, straps feel great, waist belt feels snug and comfortable.

      * Extra pockets are actually useful

      * Very waterproof, I was skeptical but this baby is at home in a torrential downpour (Though be aware it only has one pocket so if you open it the water is going straight in like a bucket)

      * Didn't make my back hot or uncomfortable, I was concerned it would but it felt breatheable despite being a sheet against your back.

      This bag is great, I am really stoked to use it more!

      Perfect for the Long Trail

      • Familiarity: I've put it through the wringer

      I just used this pack on my second thru-hike on the LT and it is honestly the best backpack I've ever used. It carries the load comfortably, stays waterproof in a downpour, and its white color makes it easy to see your gear inside the pack. Another feature I liked is that the rounded flat bottom allows it to stand upright when placed on the ground or in a shelter. I decided to go with the Southwest version because of the exterior pocket and I definitely put it to good use on the trail. It's a simple, light, and durable thru-hiking pack that I can't wait to use again.

      Perfect for the Long Trail

      So great, so lightweight

      • Familiarity: I've used it several times

      I went out on a limb and purchased this pack after a lot of research. Many of my friends went with Deuter and Northface and their packs look and work fine. I never really liked top pouches or large frames. None of the bags are waterproof either. I took this bag to Scotland and Belize where it preformed superbly in the elements and function. I highly recommend purchasing the pods from Hyperlite which are a great organizational idea. The bag is noisy but I don't believe it is obnoxious. I purchased the black for aesthetics and belief that white would be hard to keep clean. There is a hydration port, but fitting it in the interior mesh is kind of a hassle. I purchased a smaller Mission Workshop 14L hydration pouch and mounted it to the outside to act as a smaller exploration pack. Works good enough. Huge plus that this pack, and the Mission Workshop pack, are produced ethically and return manufacturing jobs to the US.

      Versatile but loud

      • Familiarity: I returned this product before using it

      Excellent build quality, great versatility--outside pocket is actually large enough to be useful, waistband pockets also functional (unlike some which are useless once the strap is cinched tight). Exceptionally lightweight, and good size for travelling (small enough to be carry-on luggage for international flights).
      My only complaint is that it's noisy--the roll-top closure has a velcro closure at the opening, so every time you open the pack you get the velcro detaching noise. Unsuitable for red-eye flights, wildlife photography, or anywhere else you want to be quiet. The Dyneema itself is a little "crinkly" noisy, but not nearly as bad as the velcro.

      Ultimate packs for, everything

      • Familiarity: I've put it through the wringer

      HMG packs are incredibly lightweight and durable. I've never had a pack stand up to so much abuse. The 2400 series is the perfect size for skiing/snowboarding/backpacking/hiking/bikepacking/you name it. The most versatile backpacks i have ever used!
