When planning your base layer on those cold all-day static hunts, you will find the Sitka Gear Core Heavyweight Bottom a key part of that system. The lofted insulation and articulated patterning quickly wicks away moisture to help keep you warm during those long periods of inactivity. The Permanent Polygiene Odor Control Technology neutralizes odor by stopping the growth of odor-causing bacteria and fungi.
For the best of both worlds match the Sitka Core Heavyweight Bottom with the Sitka Gear Core Heavyweight Zip-T, or the Sitka Core Heavyweight Hoody.

TECHNOLOGY
POLYGIENE
Polygiene Odor Control Technology is a natural fit for hunting. By permanently treating fabrics with low concentrations of silver salt, which has inherent antimicrobial properties and is naturally present in water, Polygiene safely eliminates the ability for bacteria to grow and effectively neutralizes odor.
GORE OPTIFADE CONCEALMENT
Traditional mimicry patterns based on human vision are designed to look like a specific type of vegetation or terrain. GORE OPTIFADE Concealment is the only scientifically proven concealment pattern based on animal vision to optically fade a hunter into their surroundings. By using advanced blends of micro and macro patterns to fool animal vision rather than mimic a particular shape, GORE OPTIFADE Concealment is more versatile and more effective at getting hunters close to game.
