Polartec® Delta™ is an innovative cooling fabric engineered to enhance natural cooling by optimizing airflow, dispersing moisture, and preventing wet cling. It works with the body’s natural cooling process – sweat – and is the ultimate solution for high-intensity, warm-weather activities. ### How does Polartec® Delta™ help keep you cool? ### How does Polartec® Delta™ help keep you cool? Polartec® Delta™ uses patented evaporative cooling technology, which disperses perspiration efficiently across the fabric surface. This accelerates evaporation and heat dissipation, keeping you fresh, dry and comfortable. ### What is evaporative cooling? ### What is evaporative cooling? Evaporative cooling is the single biggest way our bodies shed excess heat when we're hot. It's the reason why we sweat. As our sweat evaporates, latent heat from the skin's surface is removed. This yields a reduction in temperature on the skin surface. Polartec® Delta™ works with your body to amplify its natural cooling mechanisms. ### What makes Polartec® Delta™ different from other moisture-wicking fabrics? ### What makes Polartec® Delta™ different from other moisture-wicking fabrics? Engineered to enhance natural cooling by optimizing airflow, dispersing moisture, and preventing wet cling, Polartec® Delta™ is the ultimate base layer for high-intensity, warm-weather activities​​. Unlike standard wicking fabrics that simply pull moisture away, Polartec® Delta™ features a dual-yarn construction with hydrophilic fibers that draw sweat away from the skin and hydrophobic fibers that promote fast evaporation. This prevents the damp, clingy fabric feeling while increasing airflow, breathability, and enhanced cooling performance. ### What is hydrophobic vs hydrophilic yarn? ### What is hydrophobic vs hydrophilic yarn? This refers to the natural tendency of yarns to reject or accept water. Hydrophobic yarns do not absorb water; hydrophilic yarns will. ### Does Polartec® Delta™ have a cooling effect even when dry? ### Does Polartec® Delta™ have a cooling effect even when dry? Yes! Polartec® Delta™ has a lightweight feel that delivers an instant cooling sensation even before your perspiration activates its evaporative process. ### How breathable is Polartec® Delta™? ### How breathable is Polartec® Delta™? Polartec® Delta™ is highly breathable. Its innovative construction ensures continuous airflow to support heat dissipation and prevent overheating. ### Is Polartec® Delta™ odor-resistant? ### Is Polartec® Delta™ odor-resistant? Yes! Polartec® Delta™ has natural odor-reducing properties that help prevent unwanted smells from sweat buildup, making it ideal for high-exertion activities. ### Does Polartec® Delta™ stick to the skin when wet? ### Does Polartec® Delta™ stick to the skin when wet? No. The specialized knit structure of Polartec® Delta™ reduces wet cling, keeping the fabric light, dry, and comfortable even when sweating heavily. ### What is wet cling? ### What is wet cling? Wet cling is when a fabric gets so saturated with moisture that it sticks to the body. It occurs when a fabric is at its maximum capacity for moisture uptake and cannot move moisture from inside to out quickly enough to keep the user dry. ### What types of garments can be made with Polartec® Delta™? ### What types of garments can be made with Polartec® Delta™? Polartec® Delta™ is ideal for sportswear, activewear, and outdoor apparel designed for high-temperature and humid environments where cooling and breathability are essential. ### How should I care for garments made with Polartec® Delta™? ### How should I care for garments made with Polartec® Delta™? For best results, wash Polartec® Delta™ in cold water with mild detergent, avoid fabric softeners, and make sure to follow the garment’s care instructions. ### How can I purchase Polartec® Delta™ fabric? ### How can I purchase Polartec® Delta™ fabric?
