Sea To Summit X-Mug - 480ml / 16.2oz

Packs down small, weighs next to nothing, but still holds plenty for your drink.

Double the size of the X-Cup, the X-Mug can hold plenty to drink. The rigid ring within the rim keeps it sturdy and easy to drink out of but still allows the cup to be collapsed into a flat disk that will fit almost anywhere.

Review: Excellent flat packed mug (and bowl) for hiking, camping, and backpacking! I was sceptical at first, however this is a brilliant mug. It would be good for any outdoor activity or to use out and about. It is firm enough so you don't feel like you are going to squeeze it too tight. A great addition to any lightweight backpacking/camping kit - where every gram counts! It is a generous sized mug and it makes a good bowl as well. The measure marks inside the mug, both in metric and cups, are a useful feature.

Watch this short video to find out more about the Sea to Summit X-Series:

Food Grade Heat Resistant Silicone: The silicone we use in our products has been tested and surpasses the Japanese Food Testing process, which is the most stringent standard available. This means that there's no foul taste, no BPA and can withstand considerable heat.

BPA Free: BPA stand for 'bisphenol A'. Used since the 60's to make plastics and epoxy resins it appeared widely in outdoor products such as water bottles, pots and pans. Some research shows that BPA can get into food and water through containers and that this can have an effect on your health.  For this reason Sea to Summit has stopped using BPA wherever possible.
