Sierra Designs Flex Trail 40-60 Rucksack - Wild Dove / Peat

The Sierra Designs Flex Trail is an ultralight backpacking pack that lets you tailor the size to the trip. Cinch it down to around 40L for shorter outings, or open the horizontal gussets out to 56L for longer adventures. A hardware-based adjustable torso dials in the fit, and a lightweight aluminium perimeter frame keeps the pack light while the support stays strong. This is the Wild Dove / Peat colourway.
