A note from AliCo-Founder & Product Designer
“Newborns lose warmth quickly through their hands and feet. I designed this sleeper with a double layer of merino over the toes and soles, built-in mittens, and a two-way zip down the left leg so midnight changes are quick, gentle, and warm.”

Why choose this footed onesie?
It provides complete head-to-toe warmth without separate socks that kick off. Sized for newborns to 6 months, it keeps delicate babies cozy day and night.
How do I choose a size?
Available in Newborn (NB), 0–3 months, and 3–6 months. Designed to fit comfortably over newborn diapers. If between sizes, size up for growing room.

Feet are double-layered and enclosed.
Measured flat. Allow about ½ in (1 cm) either way.
How does the two-way zip help with changes?
One two-way zip runs from the center of the neck diagonally down the left leg. Unzip from the leg end for a diaper change, or from the neck when you are dressing them. A soft guard sits flat over the top of the zip so it does not rub their chin.
Why are the feet double layered?
We add a second layer of merino to the top and sole of each foot. This keeps little toes warmer and prevents growing feet from wearing through the knit.
How do I wash it, and will it shrink?
Wash it once before first wear to rinse out loose fibers. Then machine wash on a gentle wool cycle with liquid wool detergent. Dry it over a rack in the shade, out of direct sun, because sunlight can discolor merino. Do not tumble dry, soak, or bleach. Our superwash merino resists shrinking on gentle cycles.

How does merino work?
Nature’s temperature buffer.
Holds warmth, breathes out heat
Merino wool fibers feature a natural microscopic crimp that holds pockets of air. When the room cools down, these air pockets insulate. When the room warms up, the weave breathes freely, preventing the heat buildup common in synthetic fabrics.
Moves sweat before it turns cold.
The 2 AM solution
Unlike cotton or bamboo viscose that hold wet liquid against the skin, merino absorbs perspiration while it is still vapor and releases it into the air. Your baby’s skin stays comfortably dry, preventing the cold clamminess that triggers 2 AM resettles.
Fresher between washes.
Naturally odor-resistant
Merino wool fibers naturally trap odor molecules inside the fiber structure, locking them away until washing. Your baby’s onesie stays fresher between laundry cycles.
What research reveals about wool sleepwear and skin
Independent studies on superfine wool explain why we build sleepwear around merino.
A 12-week crossover trial of 39 children aged 4 weeks to 3 years, comparing superfine merino clothing with standard cotton.
Sportswear trials examining next-to-skin microclimates during temperature shifts.
These studies evaluated wool clothing and textiles generally, not this specific onesie. They explain why we choose merino; they do not show this product treats eczema or helps babies sleep longer.
The truth about baby sleep fabrics
Not all soft fabrics breathe. Here is how natural merino compares to rayon viscose and polyester next to baby skin.
| Fiber property | Our choiceMerino | Bamboo viscose | Polyester fleece |
|---|---|---|---|
| Moisture management | Vents moisture vapor | Holds wet liquid | Traps sweat |
| Temperature shifts | Natural crimp insulates | Cold when wet | Prone to overheating |
| Fabric processing | Naturally grown fiber | Chemical solvent bath | Petroleum plastic synthesis |
| Softness next to skin | Superfine, not scratchy | Smooth and soft | Depends on finish |
In textiles, “bamboo” means rayon viscose made by chemically dissolving plant pulp.
Frequently asked questions
Which should I choose: footed or footless?
Choose the Footed Onesie for built-in foot warmth from newborn to 6 months. Choose the footless Merino Onesie (up to 9 months) if you prefer bare feet or socks.
What keeps the zip away from baby’s chin?
A soft guard sits flat over the top of the zip at the neck, so the zip never rubs their chin or neck.
Will this sleeper last to the next baby?
Yes. Double-layer feet stop toes pushing through, and the crotch seam is overlocked then cover-stitched to prevent tension runs and seam splits over time.
Will this wool itch or scratch?
No. We use superfine 19.5 micron Australian merino. The fibers are microscopically fine and flexible, bending softly against infant skin without prickling.
Why choose merino over bamboo?
The FTC states soft “bamboo” is rayon made with harsh chemicals. Rayon viscose holds wet sweat in the fabric; merino moves moisture away as vapor, keeping skin dry.
How do I wash it, and does it pill?
Machine wash on a gentle wool cycle with liquid wool detergent, and dry it over a rack in the shade, never in direct sun. A little pilling is normal, and a battery lint shaver takes it off easily.
