We built these wind-blocking half tights to address many of the challenges of running hard in the winter. Drawing inspiration from the snug comfort of wetsuits, the NDO Half 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, while a zippered pocket securely stores a phone. 3M engineered reflectivity on the right thigh offers visibility in low light. Double-sided fabric offers maximum warmth, while bonded stretch wind block lining at front thighs protects from the elements. The tight's high-rise, elastic waistband delivers a comfortable, snug fit and locks in a base layer to keep out the wind. Reflective sash at front right thigh offers visibility in low light. Reflective material engineered by 3M for maximum brightness, on-angle reflectivity and stretch. On the back of the shorts, two large envelope back pockets allow for easy storage of gloves, hat or gels. Zippered pocket on right hip zip securely stows a phone.
