Sierra Designs Flex Lumbar 7-10L Waist Pack

TAKES WEIGHT OFF YOUR BACK AND ONTO YOUR BACKSIDE

The Flex Lumbar collection takes the same expanding gusset found in our Flex Capacitor, and shifts it vertically to work as a lumbar pack. Integrated water bottle pockets and enough room to stash a layer and some food means you have your bases covered for any day hike or mountain biking. Flex it open when you need to carry more, or cinch it down when you want a lower profile pack.
