Mountain Magic Koozie
Nice and stretchy. No bottom lets them fit a variety of containers.
The coozies look nice and I like that the bottomed of the coozie is open so your beverage can sit flat on a surface instead of feeling like it will tip over. Biggest complaint is that of the 6 coozies I ordered, 2 of them have started to get threads hanging off them and are starting to unravel
It provides enough insulation to keep the drink cold all the way to the last drop and then it fits in your pocket without any bulk to disturb you. Love it! Love your hiking socks too!
