GORE™ OPTIFADE™ Concealment is the first and only concealment system ever scientifically designed around the way a hunter’s prey views the world. Traditional camouflage relies upon mimicking hunters’ surroundings. GORE™ OPTIFADE™ Concealment breaks the mold by tricking the animal’s eyes into not recognizing the hunter as a predator by using their eyes against them.



Fit & Function

Whether you're glassing open bowls, tiptoeing through aspen groves, battling scree fields, or simply covering miles at a time, your big game pursuits run the gamut of moderate to high activity peppered with periods of pure motionlessness enduring the elements. This calls for durable weather protection, mobility, and breathability. Our Big Game system responds brilliantly to varying activity level and quickly changing weather conditions with technical fabrics and functional designs.

Our Mission

A paradigm engineer gear that is an extension of the outdoor experience and not simply a barrier between the user and the environment. By utilizing only the most advanced fabrics and construction technologies, Sitka will always design gear that is engineered to work together as complete systems, excelling in performance, function, and protection.


OPTIFADE™ Predator or Prey?

Designed for engagement ranges of 35 meters and beyond at ground level, GORE™ OPTIFADE™ Concealment Open Country pattern is optimized for spot and stalk hunting in a mountain environment. The Open Country pattern delivers concealment with a scientifically calibrated balance that both breaks up the body outline and makes you fade into the background.
