User Review: REI Doppio Stainless-Steel Tumbler

Summary

I love this little guy — it's the perfect size for happy hour on my evening stroll with the dog.

The Doppio is the perfect size for a glass of wine or a nip of something on the rocks.  I've never actually put a warm beverage in here, but I imagine I'd be happy with a shot or two of espresso in here. It's probably too small for my typical cup of coffee, but I have other vessels for that. 

Easy to clean and fits in my pocket when it's been emptied. I use it when I take the dog for a walk. I also found it sold as a two pack around the holidays for about $18.
