Deuter Aircontact 55+10, a Deuter backpack. ■Brand: deuter (Deuter) ■Category: aircontact 65+10, Aircontact 55+10 ■Details: A backpack that is useful for long-distance hiking and long trips. Comes with a rain cover. Side pockets, 2-compartment type, front access. I purchased this item in good condition and used it for one year for winter mountain climbing and alpine climbing. I haven't used it in the low mountains in summer, so I haven't sweated much in it. There is no odor. The bottom has some noticeable scratches from crampons, but the exterior is clean. The interior shows some slight deterioration, but there are no fraying threads, looseness, or stickiness, and it does not affect use.
