Our Koulin base layers are designed to keep you comfortable for everything from a long day hillwalking to short, sharp runs from your own front door.
The only thing worse than becoming a sweaty mess is staying a sweaty mess and turning into into a shivery mess. The Koulin’s 100% recycled polyester fabric wicks moisture away from your skin and dries quickly to keep you a comfortable temperature on the move.
..Read moreBody-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.
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.
Finally, Polygiene® Stay Fresh technology allows you to wear your tee for longer without washing – ideal for multi-day backpacks, travelling or just saving water!

Polygiene® Stay Fresh Technology
Origin: China
The Koulin Trail Tee 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.
Recycled Polyester
The Koulin Trail Long Sleeve is made from 100% recycled polyester. This fabric is made using post-consumer recycled content which means it may have started life as a plastic bottle!
Polygiene® Stay Fresh
Polygiene® Stay Fresh technology inhibits the growth of pong-causing bacteria, extending your tee’s lifespan and meaning you can wear it more and wash it less. Wearing your tee just one more time before washing can save huge amounts of CO₂ and water over its lifespan.
