Men's Stone Glacier Helio Base Layer Bottoms 18284-20007 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. A key layering piece for your lower half, the new Helio Bottom will quickly become your new favorite long johns. Temperature control is a breeze with the incorporation of our new Stratum Zippered Layering System. These cozy bottoms are constructed of a 94/6 poly/spandex blend and treated with an odor control Polygiene® treatment. The elastic cuffs and bootcut design ensure total coverage without the bunching of materials inside your boot's upper. Enduring cold weather starts with a proper laying system. The Helio Bottom is an essential piece for every hunt. Product Technology: 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.
