In the first mile of a run or hike, the brushed interior of the Swix Tista Midlayer Tight settles soft against the skin and adds warmth. A plain knit with 4-way stretch moves through every stride. A wide waistband keeps the fit secure on this midlayer tight. What Our Gearhead(R) Experts Are Saying:"Over long runs and hikes, the flatlock seams never chafed, even deep into the miles. The brushed interior stayed soft against my skin the whole way, so the tights stayed comfortable from start to finish."
