Loop Cap - TKWide Caps

The Loop Cap perfectly matches the stylish, low-profile design of your TKWide. The handy ring makes it easy to take your water bottle with you. The leak-proof design makes this the perfect cap for on the go. The cap is made of polypropylene (pp#5) and contains no BPA or toxins.

The Loop Cap uses the well-known TK Closure™ system. We replace the traditional external thread with a revolutionary internal thread. This patented system ensures optimal thermal performance. This cap is compatible with all TKWide bottles.
