Helly Hansen Avanche Safety Backpack

This backpack has only been used a handful of times and is perfect for winter backcountry adventures like skiing or snowmobiling. Includes multiple pockets with a back pouch big enough for probe and shovel. Chest and hip straps give comfort for long days. Only selling as we switched to a larger bag. Unsure of the exact size of this bag but I would guess around 20L. Some marks on the bag as shown in the photos (near the top of the zipper)
