The recycled soft-touch polyester fabric uses a combination of densely woven and open knit sections for a semi-opaque style and cool, consistent airflow. In addition to offset low-bulk seams for extra strength and comfort when carrying a pack, the Wisp Vest features a flattering racer-cut back for unrestricted freedom of movement, plus a Polygiene® silver ion treatment for reliable long-term freshness.
Polygiene® is an active odour control technology for use on high-performance materials. The active ingredient is a silver salt, which is a highly effective, naturally occurring antimicrobial agent. Sweat itself is odourless but it creates an environment for bacteria to thrive, Polygiene® treatment reduces odour-causing bacteria by more than 99%. Active only on the fabric surface, it does not interfere with the natural bacteria on the skin making it entirely safe next to skin. Polygiene® uses extremely low concentrations of silver salt made from recycled silver to minimize impact.
