Very good product, well thought.

I'm very happy with the bottle. It does keep my water very cold, even with the sun beating down on the black exterior. I normally don't like bottles that don't have an air hole to prevent a vacuum while drinking, but this bottle doesn't bother me. I really like that all the o-rings have pull tabs to pull them out for cleaning and I like that the cap locks back and out of the way while drinking.

There are some small things I don't like about it. While the bottle itself is insulated, the lid is not. So when it is full of cold water, especially when the bottle is on its side, the top of the lid gets condensation. This was a bit annoying at the beach because it caused sand to stick to the lid around where you put your mouth. I also really like the 40oz size, but when it is full of water and heavy, it becomes uncomfortable to carry by holding the loop on the lid and too cumbersome to hold any other way

Nice bottle. Good art. So far no problems. If it were a bit less loud when opening, it would probably be perfect.

This is ly second LTT waterbottle, my original one is an early version that originally came with only the screwcap - i later bought a spout lid for it and had to spend a bit of time shaving off sharp corners. This new version is something else again! Identical performance from the bottle itself, but this new lid is excellent, locks open, all smooth edges and I really have not noticed the external thread on the drinking spout. A perfect fit in the internal storage of my new LTT backpack too - no more dripping this one!

The size is probably a little overkill but still an amazing bottle
