Never leave home without Fox's Portage Hydration Pack and its 102 ounces of on-the-go hydration. Raised back panels promote great airflow for comfort, while adjustable sternum, shoulder, and hip straps give you a snug fit. The large main compartment provides convenient access to your goods and the side pockets organize easily lost smaller items. There's even a second reservoir sleeve for those truly epic days. The included Hydrapak reservoir features a large opening so you can easily add ice cubes or use your favorite powdered drink mix. Plus, you've got cinch straps that can handle full face helmets or rain gear and shock cords on the bottom to strap your armor down for the long climb up. There's also a sunglasses pocket and an MP3 player pocket with cable routing.
