Twist it, sip it, save it. Klean Kanteen's Twist Cap with built-in straw fits all TKWide bottles.  Cut-to-fit silicone extender slides onto the bottom of the stainless steel straw.

Twist open the straw spout to quench your thirst or snap it closed for a completely leakproof lid. The Twist Cap is a dream come true for Klean fans who want both a reusable straw and a leakproof cap. 

 Twist Cap is also equipped with new TK Closure&trade internal thread design and an easy-swivel loop. NOTE: Compatible with TKWide insulated bottles only (with internal threads).  Not recommended for very hot liquids due to steel straw.
