Piteraq is a Norwegian brand of waterproof bags I encountered at IWA.
The Kraken is their expeditionary bag, complete with padded shoulder straps for hauling. It’s available in two sizes; 100 and 140 liter and is constructed of 840D double TPU coated nylon fabric with welded construction. The waterproof zipper is a TIZIP Masterseal 10 with a 500mb hydrostatic head and can be locked. In addition to an air relief valve, there are compression straps and end corner carry handles which are quite handy.
The Kraken is offered in a variety of colors including the Crocodile seen here, as well as Black, Slate/Dark Slate, Flame/Blazer, and Blazer/Flame.
