Undiemeister T-shirts for cold days (and nights)

Where September gives us the last warm days of late summer, from October onwards those comfortable temperatures are over. The wind picks up, dark clouds gather and the streets fill with leaves. With this chilly weather, it's time to organise your winter clothes again. When the cold creeps up your arms, you sometimes feel like you should have put on an extra layer. But what? Because you don't want to look like a Michelin man. Undiemeister® has solved this problem for you with this longsleeves.

Undiemeister® Long Sleeves. Mellowood® Long Sleeve T-shirts

By popular request, we should say. Because the Undiemeister® T-shirts are popular, with temperature-regulating fabric that keeps the body warm when the temperature drops outside. But those short sleeves, could they not be made longer? And with the same fit, without the fabric becoming thicker? Yes they can, so Undiemeister® set to work, with the current collection of T-shirts as a basis.
