New model for this year (Do not check this option if this model was listed as new in last year’s Gear Guide)Constructed of all rip-stop, the Jolla is a light-weight pack with the versatility to handle knee pads or netbooks. Ventilated shoulder straps and back panel keep the pack feeling light and comfortable. A separate, zippered reservoir compartment compliments a host of storage features built into the Jolla. Included is the 100oz (3L) Hydrapak Reversible Reservoir II, which flips complete inside out for easy cleaning. The reservoir also features the new 45deg. angle Surge Bite Valve and the Quantum Clip magnetic drink tube holder.
