Category: Sub-Alpine

Type: Backpack


Completely reimagined for 2016, the Flash 20 is a simplified, lighter, more durable and weather protective daypack than its predecessor. Highly technical and suited for long jaunts away from the truck, it’s 32.75 litre (2,000 cubic inch) volume provides enough room for surplus snacks, water, and even a small bivy cache for the savvy lightweight overnighter. Bottom, side and front compression straps stabilize your load, while a new lightweight toggle bow suspension system quickly secures your weapon. Weighs just 1.6kg.

Sitka Gear Size Guide

Buy with confidence, we will happily swap sizes for you.

Sitka sizing is comparable to New Zealand and Australian sizes - so if you wear a large in a work shirt a large in Sitka will generally be the right fit too. 

Order the same size in base and outer layers, the outer layer in the same size is designed to fit over the layers that are likely to be worn underneath it.
