### ⭐⭐⭐⭐⭐ perfect for daily use or short hikes
*by H***S on June 30, 2025*

The HYDRO FLASK 621 ml water bottle is fantastic! It keeps water ice-cold for hours, perfect for daily use or short hikes. The stainless steel feels solid and durable, and the powder coating gives a great grip. It fits nicely in my bag and cup holder. Stylish, practical, and worth every cent for staying hydrated!

### ⭐⭐⭐⭐⭐ No lead!
*by H***H on February 12, 2025*

These are one of the brands that have actually tested negative for lead. Yes, as crazy as that sounds, some brands are testing positive. Aside from that being the most important thing for my family, I have zero complaints about these water bottles. They are perfect. Highly recommend and the only brand we will use.
