Baby Bodysuit

A baby bodysuit is a one-piece garment that covers the torso and fastens at the crotch, helping it stay in place during movement. Our baby bodysuits come in short- and long-sleeve styles with adjustable SnoozySeal closures.

We recommend Kaiya Baby for unisex baby bodysuits. Our ClimaCuddle® range comes in Pea Green, Dusty Pink, and Misty Blue, with the same Merino wool and rayon made from a bamboo blend across colors. Choose the sleeve length and size that suit your baby.

Use your baby’s current height and weight to check our ClimaCuddle® Baby Bodysuit Size Chart. The neckline should sit comfortably, the crotch should fasten without pulling, and the leg openings should allow movement without leaving tight marks. Age labels are a starting point.

Look for soft, breathable fabric, comfortable seams and a secure fit. Our ClimaCuddle® fabric combines Merino wool with rayon made from bamboo for softness and moisture management. Flatlock stitching and an underarm gusset add comfort where fabric meets the skin.

Shop Kaiya Baby’s bodysuit bundles, including a short-sleeve three-color 3-pack and combinations of a long-sleeve bodysuit with a sleep sack. These provide spare clothing for changes or coordinated pieces for your baby’s sleep routine.

Kaiya Baby offers affordable, high-quality ClimaCuddle® bodysuits for everyday wear. They combine a soft Merino wool and rayon made from bamboo blend with flatlock stitching and adjustable SnoozySeal closures. Choose a single piece or a bundle to suit your needs.

We recommend our ClimaCuddle® Baby Bodysuit Short Sleeve for lighter arm coverage, or the long-sleeve style for extra coverage and fold-over cuffs. 

Both offer the same soft fabric blend, Envelope Neckline, and adjustable SnoozySeal closures. Choose by fit and the conditions your baby will wear it in.

Our ClimaCuddle® Baby Bodysuit Long Sleeve has a 12–18M size listed in the size guide for children 31–33 inches tall and 25–27 lb. For an 18-month-old, check those measurements first; the long sleeves and fold-over cuffs provide extra arm and hand coverage.

Choose Kaiya Baby’s ClimaCuddle® long-sleeve bodysuits for extra coverage and the insulating properties of Merino wool in the fabric blend. For sleeping in a cooler room, use the bodysuit as a base layer under a sleep sack selected for the room temperature.
