Purchased this for my wife, given as an early Christmas gift. The quality is great, the powder coating is flawless, the holographic effect in the coating is awesome also. Thanks hydroflask

Sturdy Handle & Silicone straw

[This review was collected as part of a promotion.] This is my first 40 oz from Hydroflask as all mines were from Owala.
I love the sturdy handles in Hydroflask without the exposed screws which loosen over time with Owala.

My new favorite tumbler!!

I had so much fun designing this custom tumbler and it came out even better than expected!! I love how you can personalize it however you'd like. For me, I designed mine with the brand colors and logo for our business membership, which holds a lot of meaning for me. I'm obsessed with how it turned out & will be using it all the time!!

[This review was collected as part of a promotion.] It’s okay, holds the cold! But I don’t like the silicone straw at all!

[This review was collected as part of a promotion.] I bought this on a whim during the Black Friday sale and… I love it. It fits perfect in my car cup holder, it’s easy to carry and has a large capacity. Glad I bought it, lol!
