Take a look at the Dakine Heli Pro 20L now available at S2AS

Enough room for big missions if you pack light or smaller ones if you bring extra gloves, extra layer, extra chocolate bar—you get the idea. The Team Heli Pro 20L is the small, do-it-all pack with features demanded by backcountry or slackcountry exploration, including purpose-built snow tool sleeves, a large fleece-lined goggle pocket, and hydration sleeve that doubles as laptop storage off the mountain.

If your Dakine bag gets dirty, we recommend hand washing with mild soap (like Nikwax Tech Wash), cold water and a soft bristle brush. If hand washing is not going to do the trick, use a front loader washing machine. To ensure your backpack doesn't get tangled, place inside a pillowcase or mesh bag before washing. Always use cold water, mild soap and run on a gentle cycle. Never bleach your pack. Hang to dry in a warm but shady place, ensuring both inside and out are dry before storing.
