- Permanent Polygiene Odour Control Technology neutralises odour from sweat

Sitka's CORE Midweight Zip-T is a next-to-skin base layer built from quick-drying, midweight comfort-stretch fleece (96% polyester/4% elastane) that regulates body temperature whether conditions turn warm or cold. A high, half-zip neck lets you dump heat on the move, while permanent Polygiene odour-control technology keeps the fabric fresh through long days afield. Low-profile flatlock seams sit flat under layers and reduce chafing where packs and harnesses ride. Rather than a camouflage print, this colourway comes in Pyrite, a solid earthy tan-brown finish that suits hunters who prefer a plain, understated base layer, or who simply need a top that won't show through when worn beneath a shell or midlayer. It's just as capable as the camouflage versions in the CORE Midweight range, offering the same warmth regulation and moisture management for active days in the field. Pair it with Sitka's matching CORE bottoms for a complete layering system.
