The Crux Top is our new latest and greatest warm season base layer. Back in the 90 s you d probably say that it was the bomb . It s made from bamboo charcoal infused honeycomb fabric. This sounds weird but all you really need to know is that it wicks sweat like crazy and is extremely fast drying. It utilizes two high performance fabrics in a body mapped design to ensure you stay dry and cool while hunting in warmer climates. It also feels amazing on the skin!
