Sierra Designs Flex Capacitor 40-60 Rucksack - M/L - Butterscotch

The Sierra Designs Flex Capacitor 40-60 is an expanding backpacking pack in Butterscotch, here in the M/L torso size. Horizontal gussets let it grow from 40 to 60 litres, so it can be cinched down for a fast summit day or opened up for a longer trip, adding 15 to 20 litres of space when you need it.

The lightweight Y-Flex suspension gives the pack more support than its 1.4kg weight suggests, and dual-adjusting shoulder straps tailor the fit to your torso, which runs 46 to 53cm on the M/L. The body is 100D nylon honeycomb with 420D oxford.

Storage is spread around the pack. There are two hydration pockets on the shoulder straps, two stretch mesh side pockets, zippered hip belt pockets and a stash pocket in the bucket lid. A U-shaped top zip opens the main compartment, and the hydration sleeve comes out to double as a summit sack. A rain cover is not included.
