Why We Like The 4400 Southwest 70L Backpack

Spend a week trekking around the desert with all the camping gear you need tucked into Hyperlight Mountain Gear's ultralight 4400 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, back panel, and waist belt, and there are supportive aluminum stays that you can remove for even less weight.

It’s okay

I've used it several times
Size Bought:
5' 6"

Compared to the Six Moons with the full vest this bag is uncomfortable and has little adjustment. My short torso and wide waist leave me in no man’s land for fitment. Hip pad barely sits on the pelvis while the straps don’t sit on the shoulders at all; then my lumbar is jabbed because someone with no clue what a 5’6” 185 pound 36” waist guy looks like put two hunks of aluminum in the back with no padding to jab you. Plastic back support would be lighter, cheaper and more comfortable and more adjustment would weigh more but I’m not going to use this thing as is anyway. This thing is going to take every once of my sewing and machining skill to make it comfortable and I’m not sure it’s worth the effort.
