It laughed at 6 weeks of abuse
I just got back from a 6 week geologic mapping project in Colorado. I used this pack most every day in the field to carry all of my gear and equipment. With temperatures getting up to 110 the mesh back kept me cool. The pack was very comfortable and made my 8 hour hikes up and down large outcrops a breeze. This pack had more than enough room for everything I needed without feeling too bulky. The two pouches in front made great compartments for snacks, my brunton, and tweezers to yank cacti out of my hands and legs. If you're looking for a good day pack to carry a little more than just your lunch, the Stratos 36 is the way to go.
