    Weekends in the desert.

    Minimize your weekend warrior adventures by hiking the desert with all your camping gear in Hyperlite Mountain Gear's 3400 Southwest Backpack. 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.

    Hyperlite 3400 SouthWest

    • Familiarity: I've put it through the wringer

    Excellent pack. Functions great as a large and medium size pack, crazy light, high quality, durable, water proof, and carries a S...load of gear. This packed replaced a 6 year old Gregory Baltoro pack also a great pack; just to heavy and to many straps and compartments. Paul R

    Solid Adventure Backpack

    • Familiarity: I've used it several times

    I debated a long time before making the jump to make this purchase due to it's price tag but it's proved to be a solid purchase. You can't beat the durability or the lightweight component of this backpack. I worried about how comfortable this bag would be fully packed and weighted but it is just as, if not more comfortable than most of my backpacking backpacks. It is now my go-to overnight backpack. For the trips where I need to leave most of my belongings at base camp it comfortably sizes down to a smaller size to use as a day pack. Well done Hyperlite.

    Leap of Faith landing on Feet

    • Familiarity: I've used it once or twice and have initial impressions

    I struggled with this purchase; read reviews, forums, cross checked and did all that a couple of times over. I was concerned with this packs capabilities with the lack of a thick waist strap and without side adjustment straps, not to mention lacking load lifters and some type of "breathable" back panel etc., etc., etc. Tried on a couple of packs @ REI with good reviews and at the right weight point (or at least close). Basically these packs had way too many straps, adjustments, buckles and finicky compression straps that got in my way; I was looking for simplicity. Took the leap of faith and ordered this pack (thanks to their generous return policy) along with another well regarded pack to cross try. While the other pack would have worked just fine (light, simple, less expensive and a favorite by others), I really was drawn to the Hyperlight. Took it on a long weekend and was amazed at how comfortable this pack was, all without the things I was worried about it lacking. Simple, streamlined, form and function! We'll see how it holds up over time, but I'm pretty careful with my gear so don't expect it to be an issue. Love it.... tho can't justify the price for their mids.

    Best Pack there is. Period

    • Familiarity: I've used it several times

    I recently returned to REI my Gregory Baltoro pack. Nothing against the Baltoro, its a stellar piece. However after carrying it several times in the BC it really started to feel like a monster on my back. And the bigger the pack, inevitably the more crap you seem to find you absolutely need to bring with you. This started me down the road a lightweight packing. I tried several of the lightweight packs that are out there. When I finally settled on the HMG Southwest I found a used 2400. What I found was the 3400 will become the 2400 if you just roll it down. Great design.... When I finally got it loaded up with all my gear I would need for a 4 day trek, I took it for a little walk around hilly So Cal. Let™s just say, amazeballs. Feels like there is way less weight on my shoulders. Carries to my hip belt the way I thought a pack should. Without tons of extra straps and pockets and lids and whatever else you don't really need the Southwest is truly the backpackers dream machine. I'd be letting you down if I didn't also talk a little about their stuff sacks and PODS. By far the best again. The PODS make such great use of the space within there is zero dead spots. Another great idea. Buy this pack. You will not be disappointed.

    Awesome new pack

    • Familiarity: I've used it several times

    I have used this pack a few times now. A few day trips and one overnight backpacking trip. The things I like about it. It can go from day pack size to backpack size due to it fold down top and strapping. I found it very comfortable when fulling loaded. The material seems much more durable then my heaver pack. The main reason why I bought it was for the weight savings and it's high water resistance. No need to carry a back cover and mess with that. This will be my go to back for all occasions.
