When the trails heat up and the pace picks up, Koulin Trail Shorts are your go-to for running light, dry and distraction-free. Built for big days in warm weather, they’re soft next to skin, stretch with your stride, and stash your essentials without bounce or bulk.

Fast Legs, Free Mind

  • Lightweight outer with breathable mesh liner for warm-weather comfort

  • Stretch fabric and split hem for total freedom of movement

  • Polygiene® odour control keeps them fresher for longer

  • Two side stash pockets and zipped rear for on-the-move storage

Made to Move Fast
Koulin Shorts are designed for running long, climbing hard, and moving light. The outer fabric is quick-drying and unrestrictive, while the soft mesh inner liner wicks sweat and stays breathable in hot, sticky conditions.

The active cut, with a split hem and touch of stretch, means no pulling, chafing or flapping — just a smooth, unbothered stride whether you’re powering up steep climbs or cruising down descents.

Need to carry a few bits? The side mesh pockets are perfect for gels or gloves, and the rear zipped pocket keeps keys or cards secure without jiggling around.

Tried, Tested, Trail Trusted

Lower Impact by Design
Koulin Trail Shorts use Polygiene® natural odour control to reduce the need for frequent washing — saving water, energy and wear. Durable construction and simple design mean they’re built to last, and when they do wear out, we’ll help extend their life through repairs or Continuum recycling.

How It Is Made

Wear more, wash less
Polygiene® Stay Fresh technology inhibits the growth of bacteria, extending your shorts' lifespan and meaning you can wear it more and wash it less. Wearing your shorts just one more time before washing can save huge amounts of CO₂ and water over its lifespan

Where It Is Made

Our products are made in the best factories in the world. We know the factories personally and they have all signed up to our Code of Ethics in our supply chain. This includes the Ethical Trading Initiative base code, fair pay, safe working environments, no child labour, no modern slavery, no bribery or corruption, no materials from conflict zones and humane farming methods.

All our factories sign up to our Code of Conduct. Find out where we make our product by visiting our Factories of Alpkit factory zone.

Reducing our carbon footprint

We are carbon neutral under PAS2060 and offset our Scope 1, Scope 2 and Scope 3 operations and transport emissions. We recognise that offsetting is not part of the solution but a point to pass through on a journey to Net Zero. Carbon Neutral is just a step in that journey.

We have joined the Science Based Targets Initiative which sets independent targets for us to achieve to do our bit to limit global warming to 1.5°C. Our targets are to halve our Scope 1 and Scope 2 emissions by 2025 based on 2018 base year and reduce our total carbon intesnity by 15% every year to achieve genuine net zero by 2050.

End of life
When your partnership with this product is over send it back to us and we will pass it on to someone that needs it through our Continuum Project.
