Pretty impressed! This really gives my 21 oz Hydroflask a run for its money. I took it to work today and left in my car during 100 F weather and all my ice was still there. The internal temp of my car must have been around 115 F. An insulated bottle is a must for hot L.A. weather. I have three Hydroflasks (I love that brand) and this performed as well as they did. I wouldn’t be surprised if they are made at the same factory as Hydroflask, which is a good thing. I would recommend The Coldest Water Bottle to someone if they asked about it.

Pros
– True to its word and keeps drinks cold
-The bottle is compatible with the Hydroflask standard mouth tops and Klean Kanteen Sports Cap 3.0 tops.
-Nice oversized loop on the cap.
-Quality construction
-Nice rubber bottom to protect against drops.
