Merino lambswool mid layer

Zero Plastic. Zero compromise.

Most fleeces rely on polyester - trapping excess heat, holding odour, and shedding microplastics into the air you breathe. PureFleece® is built differently. Made from 100% Merino Lambswool and precision-woven in the UK, it works with your body - breathable, temperature-regulating, and supremely comfortable in all conditions. Developed and field-tested at the extremes. Ready for everything in between.

100% merino lambswool

Change your fleece for good.

Our unique precision weave combined with the finest Merino Lambswool performs better than any synthetic mid layer fleece. It also provides a superior loft and durability compared to a typical knitted merino top. The final fabric, in an exquisite 4 colour marl, has a natural depth and integrity which really sets it apart.
