Cosilana Long-Sleeve Wool and Silk T-Shirt - Heather Gray

The Cosilana long-sleeved T-shirt is an essential basic for babies and children: soft, light, and breathable, it offers optimal comfort in all seasons. Made from 70% organic merino wool and 30% natural silk, it combines the benefits of wool — warmth, thermal regulation, and moisture absorption — with the softness and fineness of silk. An ideal combination for sensitive skin and babies.

Why choose this Cosilana T-shirt?

• Natural thermoregulation: merino wool keeps baby warm in winter, while wicking away moisture to prevent overheating, even in mid-season.
• Extreme comfort: silk provides softness and fineness, the fabric is very pleasant on the skin, without scratching.
• Cut designed for baby: sliding neck / easy opening for irritation-free dressing and no uncomfortable side seams — ideal for delicate skin.
• Versatile: worn alone in mild weather or as a thermal layer under clothing in winter. Thin, "second skin" fabric.
• Made in Germany: handcrafted in the Swabian Alb region, in compliance with strict ecological charters.
• Organic merino wool, untreated, mulesing-free: Cosilana processes natural fibers without synthetic additives, for healthy and durable clothing.

Care & use tips

Merino wool is naturally antibacterial, breathable, and doesn't get dirty easily. The T-shirt doesn't need to be washed frequently: simply airing it out is often enough to remove odors.

For a complete wash:
• Hand wash in lukewarm water with a special wool/silk detergent.
• Use water at a constant temperature (avoid hot-cold shocks).
• Do not wring vigorously.
• Dry flat, in the open air, away from direct sunlight and heat.
• Avoid fabric softener, chlorine, tumble drying, or ironing.

When to use it?

• As a thermal undergarment in cold weather, to keep baby warm without overheating.
• As a light T-shirt indoors or in mid-season, thanks to the fineness of the knit.
• For sensitive skin or babies prone to irritation — merino wool + silk minimizes the risk of discomfort.

A natural, healthy, and versatile T-shirt — an essential for your child's minimalist and sustainable wardrobe.
