Technology - Mid-Layers
Polygiene prevents the growth of odor-causing bacteria at the source. To do this Polygiene uses low concentrations of silver salt (silver chloride), which has antimicrobial properties.
The treatment is applied at the finishing stages of textile production and field and lab tests show a high level of odor control beyond the usual lifespan of a garment.
Polygiene silver salt technology is only active on the textiles itself. Polygiene is not nanosilver.
The Stratum™ Layered Zipper System is an innovative feature found on all Stone Glacier pants and bottoms. This unique system allows the wearer to vent their layers all the way to the skin for unprecedented temperature regulation without requiring the repetitive addition and removal of layers throughout the day. Increase warmth by keeping all the zippers closed during extended glassing sessions and unzip to quickly ventilate and dump heat during periods of high exertion. No matter the situation, the Stratum™ Layered Zipper System makes temperature regulation easier than ever.
