Dakine Mission Pro Backpack 18L

From Dakine:

"The Dakine Mission Pro 18L Backpack is perfect for those quick-hit tours, like when it’s nuking snow and you just "happen to have a dentist appointment.” With room for your avy tools, a puffy, and a pocket full of excuses, this low-profile pack is made for storm laps and sneaky getaways. Ski carry, board carry, and plausible deniability all included."
