Hocosa men's wool-silk longsleeve – natural warmth for every day

Always the right temperature, never too hot, never too cold. This wool-silk longsleeve by Hocosa is an essential basic for men who value comfort, quality, and sustainability. Made from 70% organic wool and 30% silk – exactly the combination that lets your skin breathe while keeping you warm.

Why you’ll want it

Whether you tend to get cold easily or often sweat at night: this longsleeve adapts to you. Wool is breathable, temperature-regulating, and does not absorb odors, while silk provides a soft, smooth texture. The result? A shirt you can comfortably wear for several days without washing, that doesn't itch, and that provides your body with just the right amount of warmth. In the photo, Rutger is wearing size L – which is his normal size, so the longsleeve fits true to size.

Fit & use

The Hocosa longsleeve has a slim, comfortable fit and is long enough to stay tucked into your trousers. The low round neck makes it ideal for wearing under a shirt, sweater, or jacket. The seams are thin and flat, ensuring the shirt is neither visible nor noticeable under your outer layers. Available in several colors, and also available as a tank top or short-sleeved shirt.

Material & sustainability

Hocosa uses GOTS-certified organic wool and silk of controlled origin. The wool comes from sheep that live without mulesing and graze freely; the silk is carefully processed without chemical treatments. No plastic, no artificial coatings – just pure nature. The longsleeve is completely biodegradable and manufactured in Switzerland under fair conditions.

Care & washing

The beauty of wool-silk? You hardly ever need to wash it. Hanging it outside or in the bathroom while you shower is enough to keep it smelling fresh. If you do want to wash it, use cold water and a little Lanalicious wool detergent. Gently pull it into shape after washing and let it dry flat. This way, it will remain beautiful and supple for years.

Sustainable & fair

Hocosa is a small family business from Switzerland, specializing in natural underwear since 1886. Their philosophy: simplicity, honesty, and quality. Every piece is designed to last – no trends, but timeless essentials that you can wear all year round. True slow fashion in its purest form.
