Steinberg Bombole is a caving bag with a volume of 50 litres made entirely of PVC to withstand heavy use, tears, abrasions, mud and water. The Bombole sack has a tubular shape with an elongated bottom (70 cm high and 33 cm in diameter), two practical padded and adjustable shoulder straps, and two super-functional handles for easy carrying in crampons. There are also loops on the bottom. The closure is by means of a lanyard on the top, which you can also use as a lanyard for transport. Steinberg Bombole caving bag
