Merino Wool Fleece Jackets

Discover our legendary 100% Merino Wool Jackets for men and women - pure, British-made and unlike any fleece you've worn before.

Warm, soft and remarkably durable, there's nothing quite like PureFleece® - officially certified by Woolmark® - Precision woven for increased insulation and greater loft, our natural merino fleece jackets create a microclimate around your skin, transporting moisture and maintaining breathability and comfort across every season. Our 360 gsm mid layers outperform any polyester fleece jacket - and without a single synthetic fibre in sight.

Surprisingly light and wearable all year round, the fine merino fibres have a natural crimp that creates tiny air pockets, providing superior insulation to retain body heat. This is what makes a merino wool jacket genuinely different from a standard fleece: it regulates body temperature by trapping warm air close to the skin when it's cold, while allowing excess heat to escape in warmer conditions, naturally.

Whether you're layering up for the hills or wearing it as an everyday essential, PureFleece® adapts with you. Our men's merino wool jacket and women's merino wool jacket are crafted in the British Isles from 100% pure merino lambswool - no blends, no recycled plastic, no compromise.

Chosen by outdoor professionals to perform better than anything synthetic.

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.
