A double-layered and wind-blocking winter running tight with reflective details. Drawing inspiration from the snug comfort of wetsuits, the NDO Tights feature a water-repelling, double-layered fabric for warmth with a wind-blocking overlay for protection. Envelope pockets on the rear make it easy to store supplies without removing your mittens, while a zippered pocket securely stores a phone. Three-hundred-sixty-degree reflectivity developed by 3M offers visibility in low light. The NDO Tights are thoughtfully designed down to the last detail to help you perform at your very best when Mother Nature is at her very worst. We started with a custom-developed two-tone bodywear fabric that is warm and wicking, thanks to a double-sided construction that provides loft to trap body heat. Tired of the feeling of icy winds whipping through thin tights, we used an Italian-made bonded stretch wind block lining at the front thighs. The result is a running tight that feels more substantial and offers more protection, but with plenty of mobility to move freely. The tights feature a soft elastic waistband that allows you to easily tuck in a base layer for added warmth. On the back waistband, two large envelope pockets store gloves, gels or extra gear. Back ankle zippers help make it easy to pull the tights on and off quickly.
