SITKA Gear engineers gear with a specific Fit and intended end use in mind. These functional designs provide the user with authentic garments for the right situation. We can communicate our Fit descriptions in 3 different ways. Keep in mind that each garment will allow for layering in accordance to the garments place in a system and described Fit."
