User Review: Sea to Summit X-Mug

I love this cup. It is light (2.4 ounces) but not completely lightweight compared to ordinary plastic cups. The advantage is the collapsibility.

I enjoy coffee and tea (hot) at most anytime. When it comes to the outdoors, both are essential liquids to me. I enjoy a nice hot cup of joe and tea to start the day and to ease into the evening at the campsite or waypoint.

The X-Mug allows me to collapse the mug from 4.25 by 2.75 inches down to a very small size ( about 1/2 an inch), is made of food-grade silicone, and fills me up with 16 ounces of hot joe. 

It will easily clean, leaves no after taste (you need to wash thoroughly before the first use), and dries quickly. The silicone can withstand high liquid temperatures and is very flexible (except the plastic stability ring at the top).

Mine (blue in color) is nestled at the bottom of my Quart capacity aluminum anodized cookset (it fits perfectly inside).

You can't go wrong with this one.
