85% Non-Superwash Merino Wool & 15% Silk | 180 gsm
Made in Slovakia
Amazingly soft, cozy, and versatile—our Thermal Base Layer Set (also perfect as pajamas) is designed to keep your child comfortable in every season.
Crafted from a lightweight blend of 85% non-superwash Merino wool and 15% silk, this set is thinner and cooler than our 100% Merino base layers (250 gsm), making it ideal for warmer weather and transitional seasons.
Merino wool offers natural temperature regulation, breathability, and soothing softness that promotes restful sleep.
Silk adds a gentle cooling effect, helping disperse excess heat to keep your little one feeling fresh.
Whether you're heading out on summer camping trips, enjoying outdoor play on cooler evenings, packing for travel or sleepovers, or simply need lightweight pajamas for spring and summer, this set is a go-to essential. It also works beautifully as daywear under rompers or dresses, offering breathable comfort without bulk.
The snug yet stretchy fit allows for full freedom of movement without irritation. And for a coordinated look, it pairs beautifully with our Lemon Stardust Sleep Sack.

How to care for your merino wool products?
Merino needs far less washing compared to cotton and synthetic fabrics. Often simply hanging your Merino garment outside on the line for a few hours is enough for it to refresh and renew. This is because it breathes better than any other material and is naturally antibacterial and odor resistant.
Regular airing of your Baby in Merino Products will keep them fresh. When you do wash your garments, always be sure to follow the instructions on the label.
Pilling
As our wool has not been treated with a synthetic coating, it may pill.
If pilling occurs, do not despair. This is a natural process where friction causes the short fibers to migrate to the surface.
