Men's Winter Fleece

For a high performance winter fleece, nothing beats PureFleece®

Expertly woven in the UK from 100% Merino Lambswool, these 360 gsm mid layers are soft, breathable, and built to keep you warmer and drier whatever the weather.

Trusted by outdoor professionals for outperforming synthetics, PureFleece® is remarkably light and versatile year-round. The fine merino fibres naturally form tiny crimped air pockets that trap body heat, giving outstanding insulation while also allowing excess warmth to release—helping regulate your temperature in both cold and mild conditions.

Merino’s luxuriously soft fibres also wick moisture away from the skin, reducing heat loss and ensuring lasting comfort, even in the harshest climates.

FAQs Merino Wool Jackets

Yes - and it's smarter about it too. Unlike synthetic fleeces, a 100% merino wool jacket regulates your body temperature rather than just insulating it. The natural crimp in merino fibres creates tiny air pockets that trap warmth when it's cold and release excess heat when you warm up. Our 360gsm PureFleece® mid layers outperform any polyester fleece, and unlike synthetic alternatives, merino retains heat even when wet.

Yes. Unlike polyester or blended fleeces, 100% merino fibres have overlapping scales containing natural lanolin that help shrug off light showers. Merino can absorb up to 30% of its own weight in moisture and still feel dry against the skin — and critically, it retains heat even when wet, which synthetic fleeces cannot.

It's the preferred choice of outdoor professionals for good reason. A merino wool jacket works as a breathable, moisture-managing mid layer that adapts to changing conditions on the hill. It's surprisingly light, naturally odour resistant, and wearable all year round - making it equally at home on a mountain trail or a city commute.

For the best care, a quick hand wash in lukewarm water at 30° or below. That said, merino wool is naturally odour resistant and shrugs off dirt, so you'll find you rarely need to wash it at all - often simply airing your jacket outside in a breeze is enough to freshen it completely.
