Sea to Summit X-Mug

The X-Mug is a collapsible camp mug with a 480 ml capacity that is also calibrated as a measuring cup. The food-grade, flexible silicone sides collapse making it a small compact disc sized dinnerware piece that nests neatly with other X-Series dinnerware and X-Pots, while the rigid ring creates a sturdy drinking vessel and prevents scalded fingertips.
