Mildred N.wrote a review of Sea To Summit X-Mug Collapsible Mug on June 5, 2012
I like this mug. It's compact and nests with the bowl. There is a plastic taste to the semi rigid ring around the lip of the mug. And the silicone is thin, so hot drinks have to be held by the ring around the lip or with a rag. But overall I like this mug.
