Being outside and switching off. Whether it’s for an hour, a day, or as long as you want. If you don’t care about the weather, we don’t either: HERMETICdry bagsandsports toolsare your reliable companion that protects everything important to you. And they are also completely automatic and so simple: The moment you put something in a dry bag and let go of the opening, the contents are already hermetically protected against moisture, dust, and even the finest sand. This is the “just-let-go principle” – the bags close immediately and automatically. No manual locking, clicking, pushing, snapping.
