A classic fell running essential, stripped back for freedom and speed.

When the ridge is sharp and the climb is steep, the Koulin Trail Vest keeps you cool, light, and focused. Designed for fast movement in wild terrain, it’s a no-fuss layer that moves with you — from moorland sprints to sky-high scrambles.

  • 100% recycled polyester – fast-drying and moisture-wicking

  • Polygiene® Stay Fresh – reduces odour and washing

  • Body-mapped mesh panels for maximum breathability

  • Low-profile flatlock seams – no rubbing under straps

  • Rear stash pocket with secure attachment loop

Built for fell running. Made to breathe.

With its athletic cut and featherlight feel, the Koulin Trail Vest sits close to your body to wick sweat fast and disappear into your stride. Mesh zones under the arms and across the back dump heat when the sun’s out or the pace picks up.

The rear pocket gives you just enough space for keys or a gel, while staying streamlined under a running pack. It’s everything you need in a trail vest — and nothing you don’t.

Responsibly made. Ready to move.

Woven from 100% recycled materials and treated with Polygiene®, Koulin is made to go the distance with minimal impact. For long days in the hills, hot race efforts, or just your favourite loop from the back door — this is a vest that belongs on the trail.

How to measure

This size chart indicates the body measurements our garments are designed to fit. Measure yourself as described below, and use the size chart to find your size:
Chest - measure around your chest at the widest part. The tape measure should pass under your arms, and be level from front to back.
Waist - measure around your waist at the narrowest part.
Sleeve - With your arms relaxed by your side, tilt your head down and ask a friend to measure from the bone at the base of your neck, over your shoulder and down your arm to the fold at your wrist.
