Wide Flex Chug Cap

The Wide-Flex Chug Cap threads onto all Hydro Flask Wide-Mouth bottles (for example 32 oz) and is designed specifically for Hydro Flask wide-mouth threading, not as a universal cap.

The cap is leakproof when closed and features a narrow chug spout for controlled drinking flow to reduce spills and drips; note the spout cap fully detaches rather than remaining hinged.

Yes, the wide-mouth threading allows quick ice addition and easy refilling, and the cap is versatile for cold and hot beverages.

It includes a flex strap for easy carrying or hooking, offers comfortable drinking without metal rim contact, and is sized at 1.9 x 2.8 inches and 3.2 ounces for everyday multisport use.
