With summer in full swing and high temperatures putting outdoor enthusiasts to the test, staying cool can be just as important as staying dry. That’s where Polartec® Delta™ comes in. Rather than relying solely on moisture wicking technology, Polartec® Delta™ is engineered to work with the body’s natural cooling process, helping wearers stay cooler, drier and more comfortable during high-output activity.
Developed by Polartec®, a Milliken & Company brand and global leader in innovative textile solutions, Polartec® Delta™ is an advanced cooling fabric technology designed to help regulate body temperature during intense activity in warm conditions.
Many traditional performance fabrics are designed to move sweat away from the skin as quickly as possible. Polartec® Delta™ takes a different approach. By carefully regulating moisture dispersion and increasing the amount of fabric in contact with the skin through its unique knit construction, Delta™ allows sweat to remain where it can be most effective, enhancing the body’s natural evaporative cooling process while preventing the saturated, clingy feeling associated with conventional fabrics.
The result is a fabric technology that helps maintain a more consistent body temperature during prolonged activity, while offering exceptional breathability, rapid drying performance and outstanding next-to-skin comfort. Whether tackling mountain trails, fast-paced hikes, summer training sessions or everyday adventures, garments featuring Polartec® Delta™ help wearers remain comfortable even as temperatures climb.
Today, Polartec® Delta™ is trusted by leading outdoor and performance brands to deliver cooling comfort in lightweight apparel designed for warm-weather adventures. Among the brands incorporating Polartec® Delta™ into their warm-weather collections are Haglöfs, THRUDARK and Portal.
