The women's Osprey Skimmer 22 Hydration Pack has everything we need for day hikes and day trips. The classic ruck-style design has a 20-liter capacity that's just the right size to carry our lunch, camera, and extra layers on a long day hike-or hit a Saturday bluegrass festival with enough room for our water and snacks, a new festival tee, and tech to record a bootleg of our favorite band (with the artists' permission, of course). The Skimmer keeps thing comfortable with its women-specific fit, ventilated Airscape backpanel that limits uncomfortable back sweat, and a spacermesh harness with a removable hip belt and adjustable sternum strap that secures our perfect fit. As always, this Osprey pack features plenty of pockets to keep our day organized, and it also includes an Osprey Hydraulics LT 2. 5L reservoir which slips easily into a dedicated hydration compartment to keep our clothes and gear dry for the day.
