I have been climbing on the mountains for many years from different routes and with different kind of gear. One of the most important item for a mountaineer is the backpack. The term mountaineering backpack encompasses a very broad range of items. A mountaineering backpack can be a large Daypack for hikes, a technical alpine backpack or a trekking backpack.
Generally, the term mountaineering backpack refers to a robust backpack, with all the alpine necessities, which is used for activities in the mountains and in the snow such as snowboarding and ski trips, mountaineering and glacier hiking.
