This is a three part set combining the cover, made from strong 600D waterproof Oxford Nylon, with front pocket for water purifying tablets, press stud fastenings and two ALICE clips to the rear for attaching to a belt or pack, a 1Ltr plastic bottle (100% PE) and an aluminium drinking cup with folding handles.
The cover is also fleece lined, if you wet this before inserting the canteen then using convection cooling it will keep the bottle cooler for longer.
A simple and time proven design, these US style water bottle and covers are just the thing for your next adventure.
