Base Layer Technology

= Warm + Dry

PolarJock® fleece is 100% Polartec® recycled polyester yarns. Engineered for lightweight, cold-weather protection, the lofted structures create thermal air pockets to retain warmth and still allow optimal breathability. In a range of outdoor conditions, it repels moisture and speeds dry times, making it a dependable, high-performance material for an active lifestyle. Polartec® is also the creator of Eco-Engineering™ which sets the standard for sustainable textiles, including the world’s first fully recycled and biodegradable fleece.

= Tough + Lightweight

We use a polyester known for its lightweight property, silky texture, stretch, and strength. These combined benefits make PolarJock® an exceptionally comfortable cold-weather base layer for endurance sports or any activity. Its combined wind resistance and breathability help regulate sweat and prevent overheating during strenuous or extended activity. It’s also highly durable and resistant to wear and tear, ensuring it can withstand daily use and frequent washing.

= Durable Range of Movement

The elastic used in PolarJock® ensures you move freely and in total comfort to maintain optimal performance over many hours. It’s designed to move with you in a range of activities that involve repetitive movements and a wide range of motion. You get flexibility, durability, and next-to-skin comfort. These properties are especially important if you are prone to irritation or chafing. Superior durability also means these elastics retain their shape, stretch, and fit over time. They withstand repeated stretching without losing their integrity or functionality.
