This enables a longer life cycle of the garment - which also in turn reduces environmental impact. Tranemo therefore uses a mix of recycled cotton with new cotton. The underwear range consists of two different main qualities, modacrylic/cotton and merino wool/viscose. The cotton underwear is very soft, comfortable and provides a good protective first layer. The Merino wool range is also soft and comfortable and has many good natural properties. It is dirt repellent, warms even if it has become damp, does not absorb bad odour and is naturally Flame Retardant. Using Tranemo underwear will always provide a comfortable and safe protection, from the skin out. The underwear is a very important part of the Tranemo Skinsafe™ programme.
