Klim Aggressor Cool base layer long-sleeve shirt in camo

The Aggressor Cool -1.0 base layers from Klim are created using a fabric known as Coolcore. Coolcore is an engineered fabric that consists of heavily grooved fibres. The material is synthetic, but has a soft handle that is not dissimilar to cotton. The fabric allows moisture to wick very effectively any sweat generated by the body. Coolcore also allows moisture to be distributed around the garment to prevent wet patches. The material also promotes evaporation, meaning that it can have an evaporative cooling effect on the body. The material contains four-way stretch for an athletic fit. You also get low-profile stitching for enhanced comfort.
