girls zip up pajamas

Materials vary across styles and include polyester, cotton, cotton/spandex blends, microfiber or microfleece, interlock, jersey, and flannel fleece.

Zipper styles include full-length front zippers, half-length or front-half zippers, inverted zippers, and standard full-front zippers designed for easy on/off.

Some sleepers are described as flame-resistant or treated for fire resistance and note compliance with applicable safety standards.

Many sleepers include playful extras such as matching blankey buddies, sculpted or 3D hood features (ears, horns, printed eyes), foil or sculpted fleece accents, and character hood details.

Sizes span infant and toddler labels through older kids: infant month ranges (for example 3–6M, 6–9M, 9–12M, 12–18M, 18–24M), toddler sizes (2T, 3T), and children's sizes (4, 6, 7/8, 6/6X, 8), plus larger girls' ranges such as 6–14 and 14–16.

Common features that secure fit include elastic or cuffed sleeves and ankles, zipper guards or pull guards at the chin, inverted or full-length zippers, and ribbed trims.
