Your baselayer should do more than just keep you covered — it should regulate your temperature, fight odor, and keep up with your every move in the blind or field. The Sitka Core Midweight Zip-T delivers on all fronts. Built with quick-dry, midweight comfort stretch fleece, this layer balances warmth and breathability for changing conditions.

A high zippered neck lets you control ventilation, while Polygiene® Odor Control Technology ensures long-lasting freshness. Finished in Optifade Marsh concealment, it’s designed for maximum effectiveness in layout blinds, stubble fields, and marsh environments.
