Swig 63

This awesome cap fits the wide mouth Nalgene. (Or similar bottles with a 63mm cap.) The 2-piece design makes it easy to spin off without twisting your hose up. Because no one wants a twisted hose. Includes: 2-Piece Cap Straw (ready for 48oz. bottle, cuttable for 32oz.) *If you're using a hose from another hydration system that seems a little stretched out, it may need to be trimmed to create a tight seal with the cap.
