Description

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 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!

Care & Environmental Advice

Product Care Information

The Koulin Trail Vest 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 smell, wash it at 40°C. Don’t use fabric softeners or conditioners though – these stop your tee from wicking as well.

Environmental considerations

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.
