THE GRAYL WATER BOTTLE IS A GREAT WAY TO FILTER WATER IN THE OUTDOORS. IN A RECENT VIDEO OF MINE I SHOWED A COOK SET I HAD GATHERED TO MAKE THE GRAYL WATER BOTTLE FUNCTION MUCH LIKE A U.S. ARMY CANTEEN CUP COOKING SET. HAVING A WATER BOTTLE SET THAT CAN ALSO DO DUTY AS A HIKING COOK SET IS A BIG PLUS. I COMBINES A WATER BOTTLE CARRIER FROM STICHEDGEAR.COM A STANLEY COOK POT WITH FOLDING HANDLE PLUS A UCO TITANIUM SPORK TO FORM MY COOK SET.
