The Louis Garneau Zip-Leg Warmers 2 converts any pair of shorts into tights. Heatmaxx brushed lining is soft against the skin and offers full thermal protection, even on really cold rides. Special ergonomic cycling fit with silicone thigh grippers hold these warmers in place yet they're easily removed and stashed in a pocket or pack when things warm up. The 9cm ankle zipper provides easy on/off. The warmers provide UPF/SPF 50 protection with reflective accents.
