4more - 16 oz Can Adapter for the Yeti Colster - OLD BLK 3-Pack - Perfect for 16 oz. Cans of Craft Beer! - PATENTED - ADAPTER ONLY - OLD BLK 3PK

This sleeve is the perfect companion to the Yeti Colster 1.0, especially if (like me) you find yourself often drinking 16oz. energy drinks or craft beers and have the top half of the can just hanging out and getting all warm.The exterior finish is identical in texture to the black Yeti screw-top, so it almost looks as though it's an official Yeti product. It screws down tight and solid. This thing is very well made!Some have complained about the lack of insulation, even deducting stars for it. I completely disagree with that, as the extension still seals in the cold and is much better than nothing at all. And it is much cheaper than buying Yeti's new tall can Colster...I did apply a little of my own insulation to the inside of the extension, just for kicks, and it works really well. I used a small strip of HVAC bubble wrap (the stuff you insulate air ducts with) and it mates perfectly with the Colster bottom lip to keep drinks cool. It's just thick enough to "hug" the can as it slips in.I highly recommend this product to those of us still rocking the original Colster!

This is a great idea! Can’t believe yeti hasn’t made something like this already!

This product does what it says it will do. It really helped me until I got me a 16 ounce yeti coaster I drink a lot of monster 16 ounce cans and this really helped me until I was able to get me a 16 ounce yeti. Coaster! I highly recommend it!

This adapter does exactly what the product description says.It fits my 12 oz Yeti can coolie perfectly, and holds a 16 oz can snugly. The plastic is a little thin, but it's both adequate and sturdier than the lock ring that comes with the Yeti. Technically, it probably doesn't insulate as well as the 16 oz Yeti can coolie, but it works fine for me in practice, even when I'm nursing a beer.I like the fact that this takes up less space than a pair of 12 / 16 oz Yetis in my kitchen cabinet. I also like that I can switch between 12 and 16 oz cans when hanging out with friends, without having to carry two Yetis around. This adapter is small enough to put in a jacket pocket when not in use.The only down side is the price. This product can only be considered a value when compared to the obscene cost of 1) the 12 oz Yeti to which it attaches, or 2) buying a second, larger Yeti for different sized cans. If you're looking at this adapter, though... in for a penny in for a pound. Just get it; you'll be glad you did.

I have many Yeti 1 "koozies"....this little adapter is AWESOME to extend the 12oz Yeti 1 to 16oz. This doesn't work on the newer Yeti 2 with that little crappy 1/4 twist cap that sucks....get the original Yeti and these little adapters to go from 12oz to 16oz. Don't worry about..."oh my gosh...they are plastic and will let the cold out"...c'mon...the plastic these adapters are made of feels and looks just like the Yeti plastic screw on top...perfect match. I have not had an issue with my Bud Light or Monster staying perfectly cold in the Texas heat...get these!...if you have Yeti 1....if you have Yeti 2...get rid of it and get more Yeti 1's and these adapters.

Wasn't sure which one worked for the Ozark Trail 12oz cooler, but messaged the seller and confirmed that the Old 4More adapter fit. Threads worked perfectly on both the side attaching to the base and the lid. The adapter isn't insulated behind the plastic, but keeps it cooler than not having the top on the 12oz version to fit the 16oz cans.

Poor quality. Does not fit the cans it says it does, despite triple checking the right fit like it asks in the description. Even if it did fit, it’s cheap plastic crap. Robbery that they even charge what they do for this poor quality product.

The media could not be loaded.  Works exactly like it's supposed to. I was slightly worried that it wouldn't fit my RTIC can cooler (made for Yeti), but it's a perfect fit. At $9, it's a little cheaper than the $15 RTIC 16-oz. can cooler, but honestly I don't know if it's a better value. We'll see if it holds up. It seems solid, so I'm hopeful on the durability.Update almost 4 years later, and the adapter is still going strong. I used it today.
