Deuter 35+ GUIDE Backpack - Brand: deuter - Model Name: 35+ GUIDE - Color: Gray/Yellow - Purchased about 13 years ago. - Used 2-3 times. - I haven't used it recently because I've been doing more tent camping and using larger backpacks for mountain climbing. Also, the back length didn't quite fit me, which was another reason I didn't use it. - The back length is not adjustable. - The backpack has a simple structure with one main compartment and attachments for ice axes on the outside. - I previously stated that it has side pockets, but that was incorrect. It does not have them. I apologize. - You can raise the position of the rain cover a few centimeters higher than usual, which effectively increases the capacity by a few liters beyond 35 liters. The "35+" in the name refers to this. - There is a zipper on the left side that allows direct access to the inside. See photo 6.
