A waterproof suitcase (28x23x9.8 cm), equipped with 3 special rubber gaskets that cushion tremors and a valve which makes it easier to open the case when the pressure difference is high, e.g. after a flight. Foams adjust themselves to the shape of the transported item, thus enhancing the level of its protection. The suitcase is made of fabric of very high resistance to hits, kicks and falls. Additionally, in the edges of the lid there are rubber gaskets that prevent water from getting through the inside of the case. The suitcase is dedicated to safe transport of weapons, ammunition, documents, electronic equipment, lenses, glasses and other items prone to mechanical damages.
