The Osprey Women's Verve 5 Pack is a hydration pack for mountain biking, trail running and weekend day hikes. The Verve 5 is the smallest in the women's specific hydration pack series by Osprey, allowing you to get onto the trails quickly with water and not much else. The pack comes equipped with a 2L Hydraulics™ reservoir that slips into its very own direct access sleeve at the backpanel. An extra layer, perhaps a snack and first aid goes into the main section quickly and easily. Slip the perforated EVA foam BioStretch™ Harness over your shoulders and all that is left is to cinch the hipbelt and sternum strap for stability. Pedal, hike, run, repeat.
