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.
- Wicking and fast-drying 100% recycled polyester fabric
- Polygiene® anti-odour technology for multiple wears
- Body-mapped mesh panels dump heat and moisture
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.
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.
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!
