The First Wave™ takes Hydrapak's™ reversible reservoir construction and enhances the durability with 60% thicker TPU bladder material. These military grade HYDRATION reservoirs are designed to take the abuse stress of extreme operating conditions, these bladders are twice as thick and more robust than regular consumer / civilian type bladders.

The First Wave™ series by Hydrapak™ uses a 1-piece patented one-piece Hydrofusion™ Insulated Big Bore™ tube that is lighter than standard neoprene and has the insulation applied to the tube rather than a conventional slide-on cover. The revolutionary design allows users to easily maintain cleanliness in the field or home. The patented wide slide top allows for faster filling from taps, bottles or a water jerry and also provides a secure seal.

To fill: simply slide open the top, fill and reseal.
To Clean: simply slide open, reach in, reverse, clean & rinse.
