The finest backcountry mug ever, MSR has taken all the best properties of our favorite mugs and rolled them into a lightweight and functional design. A strong stainless steel lining and HDPE lid won't ever leach chemicals or taste and a non-slip, EVA foam exterior keep beverages hot-not your hands. You can remove the insulated sleeve for easy machine washing and they pack quietly inside all of our Exo, Quick, and Flex cookware as well as most others. 12 oz.
