Description

The top-loading member of the Sirrus line, and the one that stretches past a day. A cinch-closed main compartment under a fixed lid takes an awkward load without complaint, and a collapsible lower compartment gives you a second, separate space when you need it and disappears when you don't.

Thirty-six litres is enough for a light overnight in summer or a very full day in shoulder season. AirSpeed suspension, ErgoPull hipbelt, raincover in the base. Three colourways, one size.

Online exclusive, shipped direct.
