As base and insulation layers go, it doesn't get much better than the Hybrid 1/4 Zip Shirt. Essentially, this composite design blends the warmth and comfort of grid fleece with lofty PrimaLoft® RISE insulation to create a deceptively warm garment that is highly breathable and easily fits underneath outer layers. PrimaLoft is utilized on the upper part of the torso to trap heat and keep your core extra warm. The grid fleece also insulates, but is much more breathable to help regulate body temperature. This unique design also minimizes bulk underneath a jacket or bibs, making it a great choice for both big game and waterfowl hunters.
