Care instructions commonly recommend machine washing and tumble drying. Some product descriptions specify using a gentle wash cycle and low tumble-dry heat.

Batman sleepwear is offered in a range of fits across items, including snug (close) fits, regular fits, and loose fits.

Materials vary by style and include 100% cotton, 100% polyester, microfiber, jersey, and velvet-fleece constructions.

Available styles include multi-piece pajama sets (2-piece and 4-piece), short-sleeve and long-sleeve tops with pants, tank-top-and-short sets, and hooded velvet-fleece robes.

Tops are generally pullovers and bottoms use pull-on elastic waistbands. Many sets are described as close/snug fitting. Robes typically have a tie belt to secure the fit.

Size labeling varies by product. Some pajama sets use numeric kids' sizes (for example, ranges like 4–10 and specific sizes such as 8 or 10/12), and robes are offered from toddler sizes through big-boys sizes.

Some polyester 2-piece sleep sets are described as flame-resistant. A 4-piece cotton pajama set in the results is explicitly noted as not flame-resistant.
