Designed for ultimate cold-weather comfort, the Hot Chillys La Montana Bottom combines heavyweight fleece warmth with performance stretch for unrestricted mobility. Soft brushed micro-denier polyester traps heat while moisture-transfer technology keeps you dry during active pursuits. Stretch panels enhance comfort, and odor-resistant properties help you stay fresh from first chair to last run. A body-contouring fit and UPF 40 protection make this an essential winter base layer.
