Sorry, should have written this review WAY earlier before the holidays here. Still, buy yourself one and get 3 more to give others in the future as gifts. I was skeptical about the wool as I was thinking, well, "we'll see now". Turns out, besides being so unique in design and that SK story sewn on each one, it DOES NOT ALLOW YOUR DRINK TO SWEAT. I thought it may and then it would just be something neat to have but it is functional. I'd be surprised if you'd be disappointed.
