When you are building your newborn's first wardrobe, you want pieces that are practical, durable, and above all, comfortable.
At Rai & Co, we know every baby has different skin needs, sleeping habits, and temperature preferences. That is why we have expanded our signature onesie range to offer the perfect option for every climate, season, and stage.
All of our onesies feature our signature practical details: concealed two-way zips for stress-free midnight nappy changes, fold on/off feet, and built-in fold-over mittens up to size 000 to protect delicate newborn skin from scratches.
However, understanding the differences in fabric weight, texture, and breathability will help you choose the right onesie for your little one's daily routine.
The Key Differences at a Glance
-
Lightweight Bamboo (180gsm): Ultra-lightweight, featherlight, and silky soft. Designed specifically for hot weather, humid climates, sensitive skin, and babies prone to overheating.
-
Striped & Floral (Transitional Weight): Sitting between our bamboo and ribbed fabrics, these lighter-to-medium weight onesies are perfect for Spring days, breezy afternoons, and comfortable layering.
-
Ribbed (250gsm): Medium-weight cotton blend with a classic textured finish. The ultimate all-rounder for everyday, all-season wear and play.
-
Apple (280gsm): Thick, winter-weight fabric with a buttery-soft smooth finish. The gold standard for cold nights and chilly weather.
Why Choose the Lightweight Bamboo Onesie? (180gsm)
If you live in a warm climate, have a baby who runs hot, or are managing eczema and sensitive skin, our new Bamboo Onesie is engineered for you.
Crafted from a premium blend of 95% bamboo and 5% spandex, this 180gsm fabric is our lightest and most breathable yet. Bamboo is naturally hypoallergenic, temperature-regulating, and moisture-wicking, keeping your baby cool, settled, and dry on warm days. The extra stretch makes dressing effortless, while the gentle touch protects sensitive skin from irritation.
Best used for: Hot summer days, warm overnight sleeps, hospital bags for summer babies, and babies with eczema or sensitive skin.
Why Choose the Striped & Floral Onesies? (Spring Essentials)
As the weather shifts between warm sunshine and cool breezes, you need versatile pieces that sit comfortably in the middle. Our Striped and Floral ranges offer that ideal transitional weight.
Slightly lighter than our classic ribbed knit yet offering more coverage than bamboo, these styles feature delightful prints and charming details (like our Frilled Ollie Floral finish). They are soft, breathable, and designed for easy movement as your baby starts exploring.
Best used for: Spring weather, daytime outings, breezy afternoons, and stylish layering.
Why Choose the Bestselling Ribbed Onesie? (250gsm)
The Ribbed Onesie is the ultimate everyday workhorse for your nursery. It has earned its spot as a customer favourite because of its incredible year-round versatility.
Made with a 95% cotton and 5% spandex ribbed knit, this 250gsm option offers superior elasticity. The textured rib snap-backs into shape wash after wash, making it durable enough to withstand daily adventures and frequent laundering while remaining soft against your baby's skin.
Best used for: Daytime play, active movement, all-season wear, and stylish nursery essentials.
Why Choose the Bestselling Apple Onesie? (280gsm)
When cosy warmth is your top priority, the Apple Onesie reigns supreme. Crafted from a thick 280gsm cotton blend, it features our famous buttery-soft smooth finish that feels plush and luxurious.
The crotch length is specifically designed to accommodate bulkier night-time nappies without pulling, ensuring your baby stays snug and comfortable right through the night.
Best used for: Autumn and winter wear, overnight sleepwear in cooler months, and crisp morning walks.
