Small in size but mighty in skill, the Flex Lumbar pack is a smaller, hip-sized version of our Flex Capacitor backpack for day hikes, bike rides and casual outings. Thanks to our expanding gusset innovation, flexible carrying capacity comes naturally. Loosen it up to get extra space for bulky layers, snacks and trail accessories, or cinch it down to stabilize smaller loads. Two elastic mesh pockets on the sides fit most water bottles, and plush padding on the hip belt straps makes this low-back pack a comfortable, low-profile companion for many body shapes. • Stretch mesh water bottle pockets • Zippered valuables pocket • 1 main compartment, 1 hidden top zipper • Vertically expandable volume • Dual compression straps to stabilize load • Padded hip belt for on-trail comfort • 100D Nylon-Poly Ripstop • Capacity: 3-6 liters / 183-366 in3 • Weight: 8 oz / .23 kg • Hip fit: 52" / 132 cm max • Dimensions (H x W x D): 6" x 10" x 5" / 15.2 x 25.4 x 12.7 cm • SKU: 80711520PT
