Backpacks with back ventilation

Back ventilation

— this design feature provides air access to the back while carrying the backpack. Thus, increased sweating is prevented, fatigue and the risk of hypothermia from a cool wind are reduced. Ventilation is especially important for classic sports backpacks (in particular, cycling ones), as well as when worn for a long time in warm weather. It can be provided due to the special shape of the back surface, porous materials, etc.
