If you need your essentials with you, but not much else, the DaKine
Heli Backpack is your best option. At 11 liters, this pack is perfect for avalanche gear, water and gloves, but its low profile design won't slow you down or restrict your range of motion. Whether you're hiking lift served backcountry or finally getting out cat skiing, the Heli Pack is perfect if you want to feel like your wearing nothing at all. The harness is designed to fit a women's frame so you won't be swimming in a pack designed for man-shoulders.
