The Yeti Colster Adaptor is a Yeti Colster extension that allows you to fit your favorite 16oz tallboy in your usual yeti can cooler.
*FOR V1 OF THE COLSTER. If your colster is a few months old(written Oct 2020), there’s a good chance it’s v2 so it won’t fit.
Hours of thermal engineering has been put into my specific design to ensure that this is more than just for looks and convenience, that it actually is insulated to help keep the upper can cold.
Not only will it keep your can cold, but it will keep your drink warm too if that’s what you desired!
Has been tested with both Yeti Colster and Ozark Trail can coolers.
Most colors are made with the same material as your water bottles, which means unlike similar products, this one won’t be affected by leaving it sit in the sun.
