Enjoy your winter activities like never before!

The UnderWarmer heated shirt is convenient, super comfortable and best of all- it works really well! UnderWarmer was specifically designed to be affordable and convenient for the everyday guy or gal spending a long day in the cold.

Unlike hand warmers and foot warmers, which only help extremeties that have already gotten cold, the UnderWarmer PREVENTS your CORE from getting cold which causes cold extremities. How? Because a cold body core is the cause of icy extremities. Best of all, unlike all those bulky layers you’ve tried, the UnderWarmer is extremly lightweight and won’t slow you down.

Whether you are tailgating all day, hunting, fishing, or going for a long motorcycle ride you CAN stay warm for the entire day, even in negative digits. For just a few bucks, you have a portable, wearable radiator, ready to go when you are. Just grab your UnderWarmer!
