The Fröjdamark Heat undershirt is an advanced long-sleeved base layer shirt with integrated heating membranes, designed to provide optimal warmth in chilly environments. The shirt is equipped with heating elements on the body's most cold-sensitive areas, including the chest, lower back, and between the shoulder blades, providing a comfortable and even warmth as the temperature drops.


The material of the shirt consists of 84% polyamide and 16% spandex, making it quick-drying, durable, and very agile to move in. The shirt is black and is available in sizes S to 2XL. Washing instructions include hand washing or machine washing on a gentle program, but avoid fabric softener or conditioner.

When not using the shirt, it is recommended to disconnect the battery or power bank and charge it to 100%, and then store it dry for next use. The battery or power bank should only be connected to the shirt when it is in use.

A commuter's best friend! It has kept my hands warm during the chilly autumn and winter. Good battery life and nice to be able to choose between different levels of heat.

I've also used it when sitting at the computer and working/playing to warm my hands, so it gets to work even when I'm not outdoors.

Keeps my hands warm when I'm sitting in my cold office. Perfect for when the premises haven't adjusted to temperature changes.

Anders Kratz

Whether it's warming my hands during a cold round of golf, a walk, or on a skiing trip, Warmly is perfect to always have with me like a power bank. Highly recommended.

Now that the cold weather has arrived, I brought out my Warmly hand warmers, and wow! You don't realize how much you hate freezing hands until you're out in the cold while golfing!

The feeling of having them in my pockets between shots is priceless! The entire round becomes more enjoyable, and I no longer suffer from poor shot quality due to frozen hands!!!

Marcus Jönsson

I've had problems for a long time with cold hands. Whether I'm sitting at the computer, out playing golf, or doing other activities. I suspected that I would be disappointed with the performance considering the price. But I was very wrong, the product has met all my expectations with long battery life, good heat output, and that it's easy to take with me everywhere.
