Cool, breathable, and born for big days in the hills.

Whether you're weaving through summer singletrack or chasing cairns across the fells, the Koulin Trail Vest keeps you light, dry, and free to move. A classic piece of trail running kit, refined for modern pace and mountain conditions.

100% recycled polyester – soft, fast-drying, and high-wicking
Polygiene® Stay Fresh tech – wear more, wash less
Breathable mesh zones under arms and across back
Flatlock seams reduce friction under packs
Rear pocket with loop – stash keys or small essentials

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.
