Why you’ll love this sweater

This isn't just an ordinary sweater; it is a pure merino wool fleece. 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? A warm embrace that never feels stuffy.

Fit & details

The sweater fits true to size and features a classic straight cut. The zipper goes halfway down the chest, with a soft lining underneath for extra comfort. The wool chin guard prevents any itching or chafing – a smart and pleasant touch. The high collar provides a snug fit to keep the cold out, while the elastic cuffs and hem ensure the warmth stays in. 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 treatments, no superwash. Just nature at its best. You hardly ever need to wash wool; airing it out outside is usually enough. Need to wash it anyway? Use cold water, the wool cycle, and a little Lanalicious wool detergent. Dry flat to keep it looking like new.

What exactly is wool fleece?

REIFF wool fleece is made from finely knitted merino wool that is then gently brushed. This creates an airy, velvety structure that traps heat while remaining breathable. Unlike synthetic fleece, wool fleece is completely natural, biodegradable, and free of microplastics. Moreover, wool is temperature-regulating: warm in winter, cool in spring. And because the wool’s natural lanolin remains, the material is naturally dirt-repellent and odor-resistant.

What does KbT-certified mean?

KbT is the strictest European label for organic wool. It guarantees that the wool comes from animals raised in a natural, animal-friendly way — without cruel practices, chemicals, or environmental pollution. Organic farming means sheep graze on unsprayed pastures, free from artificial fertilizers or pesticides, and are never given growth hormones or antibiotics. The processing of the wool is also free of chlorine and heavy metals. This ensures you get the purest wool possible — ethical, sustainable, and healthy for your skin and the planet.
