The Cool&Hot® Thermal Bag is perfect to keep liquids cold or hot for more than 6 hours in winter or summer.
Its impermeability acts as an insulator so that condensation does not wet the inside of the backpack and thus prevents the back from getting wet.
It is carried inside the Running, Trail Running, MTB, Cycling and Trekking backpacks.
The L size cover is sized to insert 2L and 3L hydration bags.
It is also a thermal cover for 2L and 1L water bottles, jerry cans and canteens.
Reversible. Green on the outside and black on the inside.
