Sierra Designs Flex Capacitor 40-60L Backpack

EXPAND YOUR GEAR, EXTEND YOUR ADVENTURES.

The Flex Capacitor is a robust backpack designed with lightweight durability and adjustability in mind. Its expanding horizontal gussets offer 15-20L of additional capacity for longer backpacking trips, or can be cinched tight for more compact loads. For added convenience, multiple quick-stash solutions on the straps, sides, and lid give you plenty of spots to store mid-trail necessities. And the Y-Flex suspension adds extra support, so this lightweight pack has more capacity than meets the eye.
