This McGuire Gear Grid Fleece Cap provides an extra layer of insulation without the extra bulk. The fabric is breathable, preventing you from becoming overheated while trapping needed warmth. This cap is easy to layer and wear while performing high levels of physical activity while in colder environments. The fabric itself is lightweight and super soft and provides the perfect stretch without feeling too slack or too tight. This light insulation cap allows for layering so that you can still wear a looser-fitting hat or hood on top without it feeling like you're wearing a helmet. All this makes it an ideal addition to your favorite hunting, fishing, hiking, or paintball gear. Wash cold by hand. Squeeze, do NOT wring. Shape and lay flat to air dry.
