غطاء TKWide Loop

Didn't expect the cap itself to make a difference, but my coffee was still hot four hours into a road trip. The insulated steel center really does hold heat better than the plain lid. The loop handle is a nice bonus when my hands are full.

I swapped this loop cap onto my wide bottle and the stainless center really does seem to hold the cold in better than the old plastic lid. The one-piece design means no little gasket to lose, which was always my problem before. Fits tight and hasn't dripped once in my bag.

The vacuum insulated steel center actually keeps my water cold for a full workday, even when I leave the bottle in a hot car. The one-piece design feels solid and the loop makes it easy to carry one-handed.
