Sierra Designs says:

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. Flex it open when you need to carry more, or cinch it down when you want a lower profile pack.

Needs To Get A Grip

Looked a good alternative to regular backpack. Able to carry two (small) water bottles; I reuse 250ml juice bottles. Care needed when replacing, not to insert inside side strap, rather than into mesh holder. Small pockets on waist band are big enough to hold snacks etc. The expanding part proved capable of taking mid-weight tech hoodie; take care when zipping to close. The padded pocket, twist pack and user possibly too warm for phone!? But a serious concern is the seeming inability of waist band buckle-set to lock/hold straps after adjusting..... knotting free end around strap doesn't look neat! Pity, because it is comfortable in use, and seems well made.
