This long-sleeve Harkila Metso T-shirt is soft and warm, and is suitable as an inner layer, whether it’s just cool outside or genuinely cold. It is made from a temperature-regulating and quick-drying wool blend, for comfort even during high exertion. The fabric has been Polygiene®-treated to prevent odours and bacterial growth. This means it doesn’t need washing so frequently, can be washed at lower temperatures and will last longer, all of which helps protect the environment. The sleeves and collar are made from a perforated, stretch, jersey fabric that is highly breathable and quick-drying. This ensures that moisture is wicked away from the body, even during high exertion.
