Platypus Hoser 2 -
Made with the same welded plastic laminate as Platypus bottles. Hosers are water reservoirs with a drinking tube assembly that convert an ordinary fanny pack or day pack into a 'hydration sports pack' for a fraction of the cost. Hoser 2 holds 2 liters and weighs 1 oz and will fit most top pockets of backpacks. The drinking tube length is 40"
