Abstract
A rucksack, or backpack, making it possible to drink, or inhale oxygen, whilst walking. The rucksack comprises two straps wherein at least one of its two straps defines a protective, isothermic inner space, for example by means of a foldable protective band which is sewn on the upper half of the strip. A recipient is placed in the rucksack and its tube passes in this protective space and finally terminates in a valve for drinking or inhaling.
