TKWide Loop Cap absolute leak-proof for side-ways lunch box storage.
LOVE that the TKWide Loop Cap is available for the TKWide Insulated Tumbler with Cafe Cap!!! I use the Loop Cap (instead of the Cafe Cap) for absolute leek-proof hot decaf coffee in my lunch box at work. The cup can sit sideways with absolutely no leaks! Hot decaf coffee with my lunch-box dinner at work, even when I store my lunchbox in the work refrigerator! This is the only narrow, 16 oz tumbler I could find for my small hands! Sturdy, well-constructed materials. Love, Love, Love it!

Easy to Use Lid
Coming from a different brand, this lid cap was much easier to use & clean on my Klean Canteen 32 oz flask. The quality seems great, the rubber seals are easy to remove to clean so it doesn’t get gross, the handle’s functionality as well as the cap/lid in general is great. Honestly glad I made the switch over.

Product has changed
Hi there, I’ve been a customer since 2020, and I’m noticing the changes with tKwide cap from then compared to what I purchased now, it’s a lot bulkier now with a lot of rubber parts. Just a friendly feedback to bring back the older caps. Nothing was wrong with them lol change was not needed. But anyways, love klean kanteen love you guys!
