Yes, actually, in a car camping box I haven't opened for years. It's an Aladdin, though not with an REI logo. When they first came out, it was like manna from heaven. The foam insulation was very effective. But over time, I got tired of the plastic taste that always came through. Still, perfectly appropriate for a discreet beer at a car campsite. And since it's something like 10-15 years old, I have to salute the quality of the original build.

(P.S., My friends who are serious about wine/beer making tell me that the TSP+chlorine cleaner they use to clean their primaries totally kills that off-putting polyethylene taste. Have to try that sometime.)
