A new design of the classic Nalgenes bottle made of surgical grade 316 stainless steel (18/10 steel). The rounded shape makes it easy to place in a back-pack and also feels great in your hand. It is very easy to clean thanks to the wide-mouth opening. It is also possible to place ice cubes in it to keep the beverage cold for a long time. Pumping with a waterpurification pump straight in to the bottle is also easily done. The stainless steel does not give or take tast to the beverage being stored in the bottle.
