The Tna TnaCHILL™ Atmosphere Lo-Rise 2" Short is a mini bike shorts. These are low-rise bike shorts with our signature wide waistband for a smooth silhouette. These ones have a 2" inseam. They're made from our TnaCHILL™ fabric — a cotton-soft, wear-everyday jersey that feels great against your skin. Garment Dye (Gd) Colours: The unique colour of our garment dye is achieved through a special process — instead of dyeing the fabric, we dye the finished garment for a dimensional, washed-down look and soft feel. Results vary from one piece to the next, so yours is truly one-of-a-kind.
