The Chug Cap from Klean Kanteen is a replacement cap with handle - for the outdoor manufacturer's TKWide stainless steel vacuum flasks. It has a carrying handle and is leak-proof. The sealable drinking opening allows you to drink directly from the TKWide without having to remove the lid. The Chug Cap is not insulated and is therefore best suited for cold drinks. The material is BPA-free, light to clean and dishwasher safe.
