Adaptable warmth. Built for the hunt.
The Sitka Core Midweight Zip-T is the versatile base layer hunters rely on when conditions shift. Made with quick-dry, comfort stretch fleece, it balances warmth, breathability, and mobility to keep your body regulated through changing temps. The high-zippered neck adds customizable coverage, while low-profile flatlock seams reduce bulk for all-day comfort under layers. Permanent Polygiene® Odor Control Technology keeps scent in check, so you can stay focused on the hunt—not your gear.

Finished in GORE™ OPTIFADE™ Elevated II, the Core Midweight Zip-T is a reliable foundation piece from mid-season chills to late-season cold.
