When we're heading into the wilderness for a week-long escape, we've got all the necessities packed in this high-volume backpack. It's designed with suspended mesh along the backpanel that adds breathability and resists odor buildup. The hip and shoulder straps rotate with our bodies, letting us move naturally up the trail. Multiple access points and external storage areas let us access and organize our gear with ease while we're on the trail or packing up our camp. FeaturesMasculine backpack ready for long excursionsLarge volume ideal for week-long backpacking tripsSuspension mesh increases ventilation and breathabilityOdor-resistant treatment added to the backpanel meshShoulder straps provide additional suspension and comfortHydration sleeve with hanger keeps your reservoir in placeGear loops hold trekking poles and other necessary gearTop, bottom, and side entry provides easy accessibility Tech SpecsResponsible Collection: Recycled/RepurposedMaterial: 210D HD nylon (40% recycled), 420D HD nylon (45% recycled), PFC-free DWR coatingVolume: [medium/large] 65L (3966cu in)Support/Suspension: FreeFloat 360Shoulder Straps: adjustableWaist Belt: 3D comfort cradleHydration Compatible: internal sleeveAccess: top, bottom, sidePockets: 2 zippered lid, 1 stretch mesh side, 1 stretch mesh front, 2 zippered hipbeltIce Axe Carr: yesTrekking Pole Carry: yesSleeping Bag Compartment: bottom, zipperedCompression: side strapsDimensions: [medium/large] 30.3 x 12.6 x 17.3inClaimed Weight: [medium/large] 4lb 12ozManufacturer Warranty: limited lifetime Gregory Men's Katmai 65L Backpack - Empire Blue, M/L | redwoodtradingpost
