We were recently turned to Maine-based Hyperlite Mountain Gear, designers and manufacturers of ultralight outdoor packs and shelters that are made out of Cuben Fiber. The material is lightweight, rip-stop and waterproof and was originally designed for use in world-class sailing. Above are views of three HMG packs — HMG Windrider, HMG Windrider Southwest, and HMG Porter.
