For your next backcountry adventure, you need the High Sierra Lightning 35 Backpack, with a 35 liter, top loading main compartment with a gusseted drawstring closure and adjustable top lid so that you can fit in all of your necessary gear. You get the most comfortable fit with the Lightning 35 Backpack's precurved, nonadjustable dual aluminum stays that fit the contour of your back, and the contoured backpack straps have adjustable load lifters and Vapel mesh padding to keep you comfortable all day long. A stretched mesh back panel features the advanced AirFlow system to keep you cool and comfortable, while adjustable side and bottom compression straps and an adjustable sternum strap give you the snug fit and load stabilization you're looking for. An internal hydration reservoir sleeve and dual exit ports for your tube keep you hydrated while on the trail, and a removable media pocket on the backpack strap keeps your tunes handy wherever you go. If you need extra water, dual mesh side pockets hold water bottles, and a tucked away rain cover keeps the wet weather from getting in your gear.
