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 heat and moisture when you’re working hard.

The Koulin Trail Vest is ideal for running and high intensity activities where keeping cool is key. A slim cut with running vest-style shoulders is designed for moving fast in comfort. We’ve also used low profile flatlock seams that are comfortable next to the skin and won’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!
