Härkila Heat L/S Long Sleeve Shirt Willow Green/Black L

Härkila Heat T-Shirt with long sleeves, which has an integrated heat membrane, allowing you to set the temperature precisely. The clear choice for various forms of hunting and leisure activities in cold weather! WARNING! Power bank not included!

Made from 80% nylon, 20% spandex, making it quick-drying, durable, and stretchy.
With a modern fit and relatively snug.
Sewn-in heat membranes are placed at the cold-sensitive areas of the upper body: chest, between the shoulder blades, and lower back.
The membranes can be adjusted to 35, 43, or 50 degrees C using the push button on the chest.
Unlike older heating technologies, the heat membranes are flexible enough to fold together with the garment they are sewn into.
Can be easily machine washed.
In a pocket sewn into the right side of the T-shirt, there is a long textile cable with a waterproof USB connector; this allows you to connect any power bank and for example, tuck it into your pants pocket.
The pocket can be used to store the cable when it is not connected.
With a 10,000 mAh power bank, the T-shirt can maintain the highest temperature of 50 degrees C for about 7 hours at an outside temperature of 0 degrees.
To save power, the heat membranes automatically go into sleep mode when the T-shirt reaches the desired temperature. They then turn back on when the temperature drops by 1-2 degrees below the desired value, without you noticing. This way, the T-shirt is temperature-regulating, as the heating function automatically turns off when you become warm during high activity and turns back on when you sit or stand still.
A waterproof compression bag for storing the T-shirt is included.

If you do not want to use your lithium-ion battery or power bank that powers your heating products for a while, make sure to disconnect the battery or power bank from the garment and charge it to 100%. Then store the battery/power bank dry until the next season. The lithium-ion battery or power bank should only be connected when using the heated garment.
