CamelBak: Built for trail running and fast-paced hiking, the Women’s Octane 9 is designed specifically for women. The best-in-class Crux reservoir holds 2 liters of water, but if you need to carry more, stash a Quick Stow flask in one of the specifically sized harness pockets. Designed just for women, the harness allows your gear placement to be customized with the use of upper and lower pockets so you can carry your water and fuel where it's most comfortable. The stretch overflow on the back is perfect for a rain shell or extra layers while attachment points allow you to secure trekking poles, or additional gear. For trail runs, hiking, or run commuting to the office, the Octane 9 has you covered.FEATURESWomen's Specific Fit: Engineered to fit a woman's frame3D Vent Mesh: Multi-directional air flow and cushioning to maximize comfort and breathabilityDual Adjustable Sternum Straps: Offer a range of adjustments for a custom fit and increased stabilityIntegrated Essentials Organization: Keeps all your small essentials in one locationFuel and Gear Storage: Organize run essentials with pockets specifically designed for Quick Stow flasksReflectivity: For early morning or late-night runsTube Trap: Keeps your drink tube secure and easily accessibleSafety whistle: Extra assurance in case of an emergencyStretch Overflow Pocket: Quickly stash or shed a layer or rain shellTrekking Pole Carry: Easily remove or replace poles while runningTop of Pack Access: Allows easy, wide-open access to pack contents SPECIFICATIONSCOLLECTION: HikingACTIVITY: HikeUSER: Women'sHYDRATION CAPACITY: 2L/70 ozHYDRATION TYPE: CRUX™ Reservoir with Quicklink™ SystemBPA/BPS/BPF FREE: YesQUICK LINK DISCONNECT: YesGEAR CAPACITY: 7L/420 cu inPACK WEIGHT: 340g/11 ozDIMENSIONS: 39.5 x 26 x 18 cm / 15.6 x 10.2 x 7.1 inFITS TORSO: Fits a chest size of 71-116 cm/26-46 in & a torso height of 43-53 cm/17-21 inNUMBER OF EXTERIOR POCKETS: 8
