Koulin Long Sleeve keeps you cool, dry, comfortable and protected from the sun. It's our classic do-it-all technical tee, from riding bikes and long days hillwalking to short, sharp runs from your own front door. Work hard in comfort - fast-drying and moisture-wicking with breathable mesh panels. Wear it longer, wash it less - features natural Polygiene® anti-odour technology. Comfort that moves with you. The fit is relaxed enough to wear comfortably on its own, but slim enough to layer neatly under a fleece or mid-layer. We’ve used low-profile flatlock seams that are comfortable next to the skin and don’t dig in under rucksack straps. Body-mapped mesh panels under the arms and across the back provide extra breathability for steep summit slogs and sun-baked trail runs, dumping excess heat and moisture when you’re working hard. There's a rear stash pocket with attachment to keep keys safe. Fabric wicks moisture away from your skin and dries quickly to keep you a comfortable temperature on the move. And because Polygiene® keeps Koulin fresher for longer, you can pack lighter, wash less, and go further - whether you’re deep into a multi-day backpack or just skipping laundry day.

The Koulin Trail Long Sleeve has been treated with Polygiene® Stay Fresh technology, meaning you can wear it for longer before it starts to whiff. When your tee 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.
