BUILT INTO EVERY THREAD
At 3BIRD, we craft garments for people who move—through mountain mornings, long days on the water, and everything in between. That means your clothing needs to work as hard as you do. We partnered with Polygiene®, a global leader in textile performance technology, to bring two innovations to a selection of our pieces: Stay Cool™ and Stay Fresh™.
Activated By Sweat. Built For Heat.
Your body cools itself through evaporation. Polygiene® Stay Cool™ helps it do that better—and faster.
The moisture-activated cooling technology responds to your body's natural heat and sweat. Utilizing a thermo-reactive polymer matrix, it binds to fabric fibers and activates upon contact with sweat, cooling the fabric between 4.3–5.4°F. The result: a long-lasting cooling effect that keeps you feeling light, dry, and comfortable throughout the day.
Wear More. Wash Less.
Sweat doesn't smell. Bacteria does. When heat and moisture build up in a garment, odor-causing bacteria multiply—that's where the problem starts. And, that's where the benefits of Polygiene® Stay Fresh™ come into play.
Based on silver chloride—a salt naturally present in water and soil—the silver ions make it impossible for odor-causing bacteria to multiply. It's integrated into the fabric at the manufacturing stage and is only active in the material itself, so it never interferes with the natural bacteria on your skin. The result: freshness that's built in for the lifetime of the garment.
