REIFF wool fleece quarter-zip sweater – warm, soft, and incredibly durable made from organic wool

The kind of sweater you’ll want to live in immediately. The REIFF wool fleece quarter-zip is made from 100% organic merino wool (KbT-certified) and literally feels like a little cloud. Soft, breathable, warm without causing you to sweat – and ethically produced in Germany. Perfect for chilly days, walks in the cold, or just lounging on the couch with a good book.

Why you’ll want this sweater

This isn't just an ordinary sweater; it is a wool fleece made of pure merino. No polyester, no microplastics – just the natural fibers of organically raised sheep. The fabric is knitted, not pressed, and then brushed with thousands of tiny needles to create a velvet-soft fleece. This keeps it airy, flexible, and breathable. The result? Warmth that embraces you without making you feel stifled.

Fit & details

The sweater fits true to size and has a classic straight fit. The zipper goes halfway down the chest, with a soft lining underneath for extra comfort. The wool chin guard prevents itching or chafing – clever and pleasant. The high collar fits snugly to keep out the cold, while the elastic cuffs and hem ensure that warmth stays locked inside. Available in two beautiful colors: navy and sea.

Material & care

Made from 100% organic wool fleece – in other words: pure merino wool, produced organically. No chemical treatment, no superwash. Just nature at its best. You hardly need to wash wool; airing it out outdoors is enough. Still need to wash it? Use cold water, the wool cycle, and a little Lanalicious wool detergent. Dry it flat, and it will stay as good as new.

What actually is wool fleece?

Wool fleece from REIFF is made from finely knitted merino wool that is then gently brushed. This creates an airy, velvety structure that retains heat while remaining breathable. Unlike synthetic fleece, wool fleece is entirely natural, biodegradable, and free from microplastics. Furthermore, wool is temperature-regulating: warm in winter, cool in spring. And because wool fat (lanolin) remains naturally present, the material stays dirt-repellent and odor-free.

What does KbT-certified mean?

KbT is the strictest European quality mark for organic wool. It guarantees that the wool comes from animals kept in a natural, animal-friendly way — without cruel practices, chemicals, or environmental pollution. Organic farming means: sheep graze on unsprayed pastures, without fertilizers or pesticides, and receive no growth hormones or antibiotics. The processing of the wool also happens without chlorine or heavy metals. This ensures you get the purest wool in existence — ethical, sustainable, and healthy for both skin and planet.
