Why
Cold weather and stiff winds demanded powerful upper-body insulation that could be layered into a system from beneath waders and bibs without bulk. Sitka's approach was to stop the wind dead with WINDSTOPPER® by Gore-Tex Labs while maximising heat retention and mobility using PrimaLoft® Gold Insulation with Cross Core™ technology in the torso and sleeves. This cutting-edge insulator delivers a high weight-to-warmth ratio with the aesthetics and performance of down, while offering warm-when-wet functionality. Compression-resistant fleece was used in the lower torso to tuck easily inside waders or bibs. This heater of a combination of a 100% windproof fabric and down-like insulation was Sitka's solution to keeping you warm and moving freely while offering a wealth of layering options.
