not that happy
I'm not very happy I thought all Yeti products would keep the liquid cold. Besides that I like the product

Great flask, but…
Another great Yeti item. My only issue is that the cap is not attached in some way. Seems like I could easily lose it throwing one back around the campfire at night if I drop it!
