### ⭐⭐⭐⭐⭐ Worked great
*by N***J on January 5, 2026*

Perfectly fit my hydroflask

### ⭐⭐⭐⭐ Fit
*by D***. on August 18, 2025*

The covers fit and work great. My only complaint is on the original design of the covers-I have broken the flip up tab on 3 covers. The tab needs more reinforcement. Otherwise the bottle is very well insulated and durable.
