Description
Description
A small but extremely important detail!
This 2-in-1 model is designed to serve as both socks and mittens – a practical solution for newborns and babies up to 5 months old. The soft shape allows them to be used for warming feet and protecting hands.
Made from finely knitted 100% fine merino wool, they gently hug without constricting, without causing overheating, and without irritating the skin.
The soft cuff provides stability without elastic and without pressure, making them suitable even for the smallest babies.
The material is certified by GOTS, Woolmark, and OEKO-TEX Standard 100 – a guarantee of purity and safety for direct contact with baby's skin.
Merino naturally:
- regulates temperature
- maintains warmth without causing overheating
- does not prickle or irritate
- does not retain odors
- remains soft even after repeated washing
Suitable for:
- newborns and babies up to 6 months
- first outings
- additional protection on cooler days
Made in Bulgaria
Created in our family factory with attention to the smallest detail. A small garment with great significance for baby's comfort.
Why merino wool?
Regulates temperature
Merino wool "breathes" - keeps you warm in winter and cool in summer. The baby is always protected from overheating or cooling down.
Hypoallergenic and safe
Merino is naturally antibacterial. No irritation, no allergies – just comfort.
Odor resistant → less laundry, more convenience for mom.
Soft as a cloud
The fine merino wool is extremely gentle and does not sting. It is suitable even for newborns with the most sensitive skin.
One garment. Every season.
Fine merino wool doesn't just warm – it reacts. When it's cold, it retains heat. When it's hot, it cools.
Heats without overheating
Merino fibers create microscopic air pockets that retain body heat without adding bulk. When the baby sweats or the air is humid, the fibers absorb moisture and release additional warmth.
Quick tip:
Merino is the base layer that keeps the heat close to the body.
On top of it, you add an outer layer depending on the weather (snowsuit/overall).
It is important for the merino to be next to the skin - no cotton underneath it.
Two clothes instead of four
Babies move between warm and cold – from the stroller in the sun to the shade, from indoors to outdoors. Merino wool handles these changes without needing a change of clothes. When the baby is active, it wicks away sweat. When at rest, it retains warmth.
Quick tip:
Merino as a base layer + one more light layer on top depending on the situation. For outdoors, add a winter onesie.
No need to layer too many clothes.
When the weather changes during the day
The most challenging seasons for dressing a baby - it's cool in the morning, warm at noon, and then cools down again in the evening. You change them three times with cotton. Merino reacts on its own - it releases heat when it's warm and retains it when it gets cool.
Quick tip:
Merino doesn't make you overheat like synthetics do—even when the sun beats down unexpectedly. That's why it's the favorite layer for mothers who don't want to carry a spare wardrobe in their bag.
Cooler than cotton. Yes, really.
19 micron fine merino is thinner than most cotton bodysuits. Cotton absorbs sweat and stays wet - it sticks and irritates. Merino absorbs sweat as vapor, evaporates it, and cools the skin. It also provides natural UV protection. The baby stays dry, without a rash.
Quick tip:
Did you know that Bedouins wear wool in the Sahara? Fine merino is cooler than cotton in the heat.
Dry baby = calm baby
In the heat, the main enemy isn't the warmth, but the moisture. Trapped sweat irritates baby skin and leads to rashes. Merino wool absorbs up to 30% of its weight in moisture without feeling wet. The lanolin in the fibers stops bacteria – no odors even on the hottest day.
Quick tip:
On hot days, a light merino bodysuit is a better choice than cotton – it doesn't stick and protects against UV rays.

No, merino isn't itchy!
When they hear "wool," many parents imagine prickliness and discomfort. The truth is, merino wool is completely different.
The fiber of fine merino is about 4 times thinner than human hair – so fine that it doesn't irritate the skin or prickle.
Instead of sticking out and pricking, merino gently bends and follows the body's movements. That's why it's suitable even for the most sensitive baby skin – right from the first days.

No pricking, no irritation
