### ⭐⭐⭐⭐⭐ perfect fit for my running pack

These fit perfectly in my running pack. They are lightweight and easy to use.

### ⭐⭐⭐⭐ One is perfect, but the other one leaked.
*by M***N on June 29, 2022*

The one that didn't leak is very nice and lightweight even filled with water (17 oz size). Easy to carry in small purse side pocket if not filled too full. I used it to drink from under a mask on airplane! Easy to pack. Just wish the one hadn't leaked all over the counter top!
