SITKA MEN'S TRAVERSE HUNTING BIBS: Combining comfort, performance characteristics, and warmth, the fleece-lined Traverse Bib adds versatility to your SITKA system. Whether you'll be spending your days in the woods, up in a tree stand, or out in the fields, these pants are designed to eliminate the distraction of discomfort. Constructed with fabrics made from recycled materials, the Traverse features an ultra-quiet polyester knit fabric that has a durable water-repellent finish to protect you from weather and mud. 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 the 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 the game.
