The Arktis range of waterproof insert bags stand alone in the market place.  Manufactured in a 80gm ripstop fabric with a perfectly balanced 80gm2 neoprene rubber coating they are robust and hygienic but much lighter and supple than the standard thick rubberised insert bags.  The 120 Litre version is suitable for a large bergan.

The 25mm polypropylene webbing used on the closure has a unique stiffener on one side, giving a tight seal once rolled over.  The sealed seams render these vessels of varied size watertight.  Ideal for use as a rucksack liner, water carrier, dry/wet bag, divider, pillow or flotation device.
