Stripped back. Performance focused.

Koulin Trail Vest is made for mountain movement — with a close, athletic fit that wicks sweat and keeps you cool, even on steep climbs in the midday sun. The lightweight fabric sits softly against your skin, while breathable mesh panels let heat escape when you’re working hard.

A small rear pocket adds practical storage without bulk, and the low-profile seams won’t chafe under running vests or hydration packs.

Lower impact, mile after mile.

Made using 100% recycled fabric and treated with long-lasting Polygiene® odour control, the Koulin Trail Vest helps you pack light and tread lighter. Whether it’s your local loop or a Lakeland classic, this is a top that earns its place in every kit bag.
