15oz double walled stainless steel mug with a carabiner clip handle. Perfect for camping, festivals, and any other outdoor activity because you can hook it on just about anything and it's lightweight so it doesn't add extra bulk to your pack. Night design on one side/Day design on the other. Top rack dishwasher safe but to prolong the life of your cup and the print, hand wash only with mild detergent. Not for use in the microwave.
