Ergonx 4 in 1 Aluminum Cooler Mug

This stubby cooler as we generally call them i find a bit unique in that it has an extra screw on lid that surrounds the can and keeps it cooler for longer. Also has a seal on the other lid which is used for hot beverages that can be shut tightly. You could even put some small ice cubes under the can (375ml) while it is in the mug, there is a small gap below it. Or you can just use it as a mug. It seems to feel pretty robust as well. For me it came free with the purchase of their Ergonx work boots which i can highly recommend to anyone with sore or problematic feet, the best.
