Hyperlite Mountain Gear optimized the minimalist Summit 30L Backpack for passionate alpinists, backpackers, thru-hikers, and other goal-oriented adventurers. Take the 30-liter Summit Pack on your El Cap Nose-in-a-day ascent, the sub 24-hour Grand Teton summit attempt, or anytime you're pushing the super ultralight fastpacking limits. Combining the minimalist elements of Hyperlite's Metro pack with functional basic daisy chains, fully sealed seams, shock cord lacing, and compression straps, the Summit securely holds enough water, food, extra gear and clothing for your big day. And it's streamlined so nothing gets in the way while you are en route. Bring it on your bigger adventures-it's light and easy to stuff into a larger pack. Or just use this sweet rig for cycling, walking, or commuting to work. Made with a waterproof Dyneema hybrid fabric, the Summit is also highly water-resistant and tough despite its incredibly light weight.
