Base Layer Technology
for Your Privates

Hydrophobic + Breathable

= Warm + Dry

The PolarJock® pouch lining is constructed from 100% premium Polartec® fleece, engineered for lightweight, cold-weather protection. The lofted structures in this fleece create thermal air pockets to provide insulative warmth as well as optimal breathability and moisture-wicking properties to keep your package warm and dry. You get technology designed for dependable, high-performance protection in the coldest conditions. 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.

High Strength-to-Weight Ratio

= Tough + Lightweight

We use a polyester wind resistant layer 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 outdoor work. 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.

Resilient Elasticity

= 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 as well as next-to-skin comfort. These properties are especially important if you are prone to irritation or chafing due to the reduced blood flow of “winter penis.” Superior durability also means these elastics retain their shape, stretch, and fit over time. They withstand repeated stretching without losing their integrity or functionality.
