Armatech
Armatech is an extremely densely woven polyester fabric developed by Jack Wolfskin. This has a polyurethane coating and is therefore permanently waterproof.
The advantage of the fabric is the high UV resistance and color fastness. In addition, Armatech is very durable and resilient thanks to its fine and dense weave. Armatech is primarily used for its backpacks, daypacks and accessories.
