The Delta Polartec raglan sweatshirt from M-Tac is a great option for everyday use. Made with durable Micro Series fleece (100% polyester) from the world-renowned Polartec® company. This material feels good against the body and keeps you warm. The jacket has a mid-chest zipper, which makes it much easier to put on. The stand-up collar guarantees additional protection of the neck against the cold and wind. Special raglan sleeve cut provides comfort and does not chafe. Such cut helps to achieve an unusual shoulder shape that results in a stylish rounded silhouette. High-quality material from Polartec® has excellent thermal insulation properties. Unlike natural fabrics, it does not accumulate, but removes excess moisture from the body, providing comfort. In terms of thermal properties per 1 gram of material, Polartec® is twice as good as sheep39;s wool and cotton. Products made of Polartec® can be worn both separately and as an inner layer under windproof clothing.The YKK company is a world leader in the fastening production.
