Thermal Union Suits for Girls Black

$14.244.4 from 1,202 ratings

We cut this one-piece union suit from a 60 percent cotton and 40 percent polyester thermal knit. The front fastens with buttons from the neckline down through the torso. It sits close enough to layer under pants and sweaters without bunching up. Dyed in solid black.

On our ladder this one is Warm. Thermal and waffle knits that hold heat without much bulk.

What it is made of

Thermal knit blend
The 60 percent cotton and 40 percent polyester knit holds its shape and warmth. Cotton keeps the inside soft against bare skin, while the polyester adds strength across the seams and prevents stretching out.
Full button placket
Buttons run straight down the center front for straightforward dressing. We sew each button securely so the placket lies flat across the chest and torso without pulling open or gapping during wear.
Solid black finish
The fabric is dyed solid black throughout, including the rib-knit collar and cuffs. The dark color hides everyday scuffs when worn around the house and pairs under any winter outfit without showing through.
Machine wash care
Wash this union suit in the machine on a cold cycle. The cotton-poly blend resists shrinking in the dryer and retains its deep black shade wash after wash without bleeding onto other laundry.
