潛水布保溫瓶套

The neoprene is thicker than I expected, so my bottle feels properly cushioned when it clunks around in my gym bag. It's light enough that I forget it's there, but the fit is spot-on for my usual size. Definitely worth grabbing another one for my other bottle.

Finally, a cover that actually fits snugly without slipping off. The neoprene is thick enough to cushion against bumps in my bag, and the opening allows easy access to the bottle.

Bought this mainly to stop my bottle from clanking around in my bag and it does exactly that. The neoprene stretches just enough to fit my 750ml bottle snugly without being a pain to pull on and off. It's lightweight too, so I barely notice the extra bulk.
