Designed for optimum breathability, the lightweight Icebreaker Comet Shorts are ideal for everything from trail running, long hikes, and other high-output activities. The minimalist design provides uninhibited motion and amplifies airflow by combining a recycled polyester main body with panels of corespun eyelet mesh. Merino wool adds durability and strength while retaining next-to-skin softness. Inside there is a stretchy inner short made from Cool-Lite® jersey, providing support, breathability and quick-drying performance. The elastic waistband provides a snug fit, and reflective side trim improves visibility while running at night.
