In anticipation of lots of boating this season, and my first grand canyon trip, I am trying to find the ultimate beverage holder. I figure it should accomplish a few things:
1. Keep beverage cold
A simple foam koozie is usually enough, but foam can stick to the cans a bit making removing the can harder and tearing the foam. Neoprene dosen't insulate quite as well, but it is easier to remove the can.
Thermos makes a vacuum lined koozie that is supposed to be great for 105║ days.

2. Keep beverage easily accessible
There seem to be 2 main options - the beer necklace or a frame mounted holder.
The beer necklace has the advantage of going anywhere you do, so it goes into camp, to concerts, and on side hikes if you want it to - you can also use it paddle boating or on a friends raft. Any koozie can be converted to a necklace with duck tape and some webbing. Or you can buy pre-made:
The frame mount means not having a rope tied around your neck while boating.

3. Keep beverage separate from river water
There is a company that makes tops for 12 oz cans, cheap and probably effective:
Soda Can Lid - Pop Can Lid
But it is kinda like a sippy cup, so it might not win any cool points. On the plus side there is a lanyard hole so it will attach to the necklace, then you can take it on and off and not lose it while drinking.
On the cooler side is the BottleIt - converts cans into bottles:
Not sure about how much beer ends up on top of the can with this - or if it really matters, but dirty can lids will probably contaminate your beer.
I think my favorite so far is the neoprene koozie necklace with the sippy cup lid - whats your favorite?
