Superfine merino for the first 3 months
Stretchy superfine merino wraps newborns in breathable, moisture-wicking comfort.
A fine zip on your baby’s left side closes it with their arms inside. There is no hood and the neck sits snug. It is made long, with stretch and room at the hips, so their legs stay bent and do not reach the bottom before about 3 months. Stop using it as soon as your baby shows signs of rolling, and do not use it past 3 months.
“Newborn skin is delicate and easily irritated by trapped dampness. I designed this swaddle in stretchy Australian merino to give newborns that secure, womb-like feeling without the trapped heat of synthetic fabrics, keeping them peacefully dry and settled.”

It closes with a fine zip down your baby’s left side, with a soft guard sewn flat at the top. Arms go inside, with hands resting on the chest or up by the shoulders. There is no hood, and the neckline sits snug. It is long, with stretch and room at the hips so their legs can stay bent.
One size for 0–3 months. It is made long, so most babies’ legs do not reach the bottom before about 3 months. Stop using it as soon as your baby shows signs of rolling, and do not use it past 3 months. Then move to a sleep sack with arms free.
0–3 mo
One size for 0 to 3 months. Stop using it at the first signs of rolling, and by 3 months at the latest.
Measured flat. Allow about ½ in (1 cm) either way.
Stop at the first signs that your baby is trying to roll. Do not wait until they can roll completely, and do not use it past 3 months. Always place your swaddled baby on their back on a firm, flat surface in a bassinet, Moses basket or co-sleeper, with nothing else inside.
Yes. In mild rooms, wrap over a diaper or our sleeveless Merino Singlet Bodysuit. In cooler rooms, layer over our long-sleeve Merino Bodysuit. Check baby’s chest: warm and dry is just right.
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.
It's so soft, and the merino feels lovely compared with the cotton swaddles we had before. Easy to get on, too.1.2K
I was worried wool would feel scratchy. This is softer than most of our cotton pieces.847
It's stretchy and easy to get on, even when he's wriggling. The fit is snug without feeling tight.2.3K
We were a bamboo family until this. Bamboo always felt damp and clingy to me. Merino feels dry and soft.596

It's lovely quality, and the fabric feels breathable. I've already recommended it to two friends.729
Wool for a baby sounded fussy to me, but it's a gentle wool cycle and hang to dry. That's it.1.5K
The same fleece that carries sheep through hot days and cold nights now protects your baby’s sleep.
Nature’s temperature buffer.
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.
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.
Merino wool fibers naturally trap odor molecules inside the fiber structure, locking them away until washing. Your baby’s swaddle stays fresher between laundry cycles.
Independent studies on superfine wool explain why we build sleepwear around merino.
Sleeping in wool promoted faster sleep onset compared to cotton, in a laboratory study of 17 young adults at 63°F.
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 swaddle. They explain why we choose merino; they do not show this product treats eczema or helps babies sleep longer.
Not all soft fabrics breathe. Here is how natural merino compares to rayon viscose and polyester next to newborn skin.
| Fiber property | Our choiceMerino | Bamboo viscose | Polyester fleece |
|---|---|---|---|
| Moisture management | Vents moisture vapor | Holds wet liquid | Traps sweat |
| Overnight 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.
Nurse-designed construction for newborn skin and easy, safe swaddling.
Yes. It zips closed at the side, so there is nothing to unwrap or work loose, and the stretchy merino knit holds gently around your baby.
Stop at the very first signs of your baby trying to roll, and by 3 months at the latest. Move straight to our 3-Seasons Merino Sleep Sack so baby’s arms are free.
No. We use superfine 19.5 micron Australian merino. The fibers are exceptionally fine and flexible, bending softly against sensitive skin without itching.
The FTC states soft “bamboo” is rayon made with harsh chemicals. Rayon viscose holds wet sweat against newborn skin; merino releases moisture as vapor, keeping baby dry.
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.
