Plus, it has a No Sweat™ Design, which means you say adios to damp or frostbitten hands.

  • No Sweat™ Design keeps condensation from forming

Rambler Colster is rated 4.7 out of 5 by 1554.
Rated 4 out of 5 by from Great...but not quite a 5 Other reviews have noted the issue that I have....This unit fits cans perfectly, but long-neck bottles wiggle a bit within the stainless portion once set. This is the only reason that I don't give it a 5-star rating. Beverages stay cold and the empty-bottle glass is cold to the touch once you remove it. There is a solution to the bottle wiggle. See my added before and after photos. Just get a thin foam huggie and put the bottle in that before you insert this combo into the Colster. This not only eliminates the bottle wiggle, but adds insulation to the set-up....badda bing!

Rated 5 out of 5 by from The last Koozie you will need I love the colster. I used it in Destin and it must of been 94 F. It was crazy hot on the sanbadr that day. Either way, I got to talking to my friends and had not had a sip of my beer in almost 2 mins, I know. The beer was still cold after chatting with friends even after 8/9 mins. One of my friends is a real talker. It's a plus when everyone on the sandbar and boats walk gives you a thumbs up when you are telling a yeti. Ps- have the colster, 20 and 30 oz ramblers. Highly recommend those as well. The lowball is also a great addition for whiskey, or bourbon drinks. Cheers
