Designed to help keep your training on track through the colder months, these thermo tights provide warm, cozy comfort without any compromises to your freedom of movement. For those who love to run outside no matter how cold it gets, it's hard to find thermo tights that are warm enough but not overly bulky. We use cozy, thermo-brushed knit fabric and our Kinetic Garment Design process, which orients the fabric in the optimal direction of stretch for each section of the tights. This optimizes ergonomics and freedom of movement while also minimizing the number of seams to help prevent skin irritation.
