Perfect size

I liked this very large size and the carry on top that is attached to the straw is awesome, I didn’t have to do anything as change from one top to another.

Love the look

It’s stylish and the engraving is so noticeable. I was a bit disappointed I didn’t order the right mouthpiece (wanted soft) but happy with the handle which is a big improvement over the last model. My water stays cool even after being in my hot car all day! And the boot for the bottom helps it’d I drop it. Thank you for a great product!

Hydration always at hand.

My kids are always drinking from my water bottle when we are out. I appreciate the 40 ounce for holding all the water we need while also fitting in my cupholder. I like the color although I thought it would be lighter. I also really like the flex straw cap it makes it easier to carry the bottle and cleaning it is also simple.

Love the bottle, hate the cap

When are the regular caps coming back? I hate the caps with straws.
