Overview - The Flash 18 is a lightweight daypack when all you need to carry are items like water, snacks and a few layers. It packs down to almost nothing and can be flipped inside out to be a stuff sack. When I'm traveling or backpacking, I often take this to use as a day pack. It also works well as a pack to wear while multi-pitch climbing.
Lightweight - The pack is lightweight and compact. Rolled up, it's about the size of a hotdog
Simple drawstring closure
Hydration compatible - There is an internal sleeve for hydration and a hydration port
Shoulder straps, hip belt and sternum strap - The shoulder straps are comfortable and there's a webbing hipbelt and adjustable sternum strap
Interior storage - My pack has a couple of pockets for storage. The latest one has a zippered pocket which keeps keys and valuables secure
Recommended uses - Everything from day hikes to sightseeing to outdoor concerts. Great as a small multi-pitch climbing pack as well.
