When the trails heat up and the pace picks up, Koulin Trail Shorts are your go-to for running light, dry and distraction-free. Built for big days in warm weather, they’re soft next to skin, stretch with your stride, and stash your essentials without bounce or bulk. Fast Legs, Free Mind • Lightweight outer with breathable mesh liner for warm-weather comfort • Stretch fabric and split hem for total freedom of movement • Polygiene® odour control keeps them fresher for longer • Two side stash pockets and zipped rear for on-the-move storage Made to Move Fast Koulin Shorts are designed for running long, climbing hard, and moving light. The outer fabric is quick-drying and unrestrictive, while the soft mesh inner liner wicks sweat and stays breathable in hot, sticky conditions. The active cut, with a split hem and touch of stretch, means no pulling, chafing or flapping — just a smooth, unbothered stride whether you’re powering up steep climbs or cruising down descents. Need to carry a few bits? The side mesh pockets are perfect for gels or gloves, and the rear zipped pocket keeps keys or cards secure without jiggling around.
The Koulin has been treated with Polygiene® Stay Fresh technology, meaning you can wear it for longer before it starts to whiff. When your garment does start to pong, wash it at 40°C. Don’t use fabric softeners or conditioners though – these stop your tee from wicking as well.
