Sitka Whitetail Collection. Whitetail hunting from a static elevated position is an exercise in patience, endurance, stealth and precision. SITKA Whitetail gear is purposefully designed for the hunter to excel in all these aspects by using advanced fabrics, like GORE-TEX® and PrimaLoft® to keep the weather at bay from early to late season so you have more time in the stand. For ultimate stealth we combined GORE™ OPTIFADE™ Concealment Elevated II, the only concealment pattern scientifically engineered to confuse the vision of deer, with innovative fabrics that suppress sound to outsmart deer in any environment across the country.
