Sets often include a wrap-style shirt (gi top), pants, a belt, and a headband. Other options are one-piece jumpsuits or bodysuits with an attached hood and sometimes enclosed feet.
Sizes generally cover toddler and kids ranges. Common suggested age groups shown in listings are 2–5 years and 5–12 years, and some descriptions specifically note toddler boys' sizes. Availability varies by seller, so check each product page for exact size options.
Most listings recommend comparing your child’s measurements with the seller’s toddler size chart and double-checking those measurements before ordering to ensure a proper fit.
Materials vary by style. Many costumes are 100% polyester. Bodysuits and other stretch pieces commonly use polyester/spandex blends (examples listed include 94% polyester/6% spandex, 95% polyester/5% spandex, and 88% polyester/12% spandex). A replica-style gi may use a twill blend such as 85% cotton/8% rayon/7% polyester.
Skeleton jumpsuits typically use a center-back zipper and have fully enclosed feet; listings state this design makes the suit easy to put on and take off.
