KLIM's high performance purpose-built base layers feature chemical-free fabric technology for cooling, moisture-wicking and evaporation for any hot-weather riding activity. The new women’s Solstice -1.0, KLIM’s coolest base layer, is a solid weave that can also be worn as standalone layers across the line. The men’s Aggressor -1.0 line, now in its second generation, is a mesh weave meant to be worn as a base layer, using riding-specific construction redesigned for exceptional comfort.
