Tag Archives | Flex Capacitor 40-60 Pack

For most backpackers, the Flex Capacitor 40-60 Pack will be ideal for 3-season trips between 3 and 7 days in length. It weighs just 2.5 pounds, but it’s fully featured: durable all-nylon construction, six external pockets, two compression straps, removable hydration sleeve, and a suspension system that was tested with loads up to 70 pounds.

Its most unique feature is a front-side gusset that can be collapsed or expanded to uniformly adjust the pack volume between 40 and 60 liters. Normally, two packs would be necessary to cover this range.

The price is right, at just $200. It is currently available directly from Sierra Designs, with wider distribution planned in the spring 2017.
