  • The durable, stainless steel build makes your beer all-terrain and virtually shatter- or puncture-proof. Fits standard 12 oz cans and bottles and keeps drinks colder longer than any standard drink jackets.
  • The only problem with enjoying a soda, beer, or refreshing sparkling water is that it’s usually gone warm before you’re finished with it. Typical drink holders are nice for your hands but do basically nothing for your drink. The YETI Colster perfectly encases your can or bottle keeping all the glorious coldness right where it belongs, inside.
  • The heavy-duty stainless steel walls are sweat-proof, so you can high-five with impunity while enjoying a tasty beverage.
