Rating: rated 5 of 5 stars

When I don't need my full pack this is my go to.

It has 2 ice tool attachments and ski carrie loops.

For a small pack it does a lot. It's light and can fit plenty of gear for going out on day trips either backcountry skiing, climbing or just winter hikes. It can also be made more light-weight or better for climbing with the removeable hip belt.

The Trion Light is also hydration system compatible, so unless Mammut comes out with a small pack better than this one I will be keeping it for a while.
