[Clothing] Baselayer
Koulin Trail Long Sleeve Zip
£29.99 £34.99
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 provide extra breathability for steep summit slogs and sun-baked trail runs, dumping excess heat and moisture when you’re working hard. If you still find yourself overheating, the zip neck can be undone for ventilation, as well as offering some extra sun protection.
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!
