PRODUCT DETAILS
What's in the Box
- Muscle-chest jumpsuit with metallic gold fish-scale armor print and full-length green sleeves
- Attached foam-backed gauntlets with ridged Atlantean detailing
- Green pants with scale texture and sewn-in 3D boot tops
- Shaped foam belt with ornate gold Atlantean print and velcro fasteners
This Kids Aquaman Costume turns any young DC fan into the King of Atlantis, with fiber-padded muscle chest, metallic gold fish-scale armor print, and foam-backed gauntlets that bring Jason Momoa's iconic superhero look to Book Week or Halloween. The jumpsuit's three-dimensional elements — ridged boot tops, sculpted gauntlets, ornate belt — add serious superhero presence without weighing your kid down.
The standout is the digitally printed armor: metallic gold scales across the torso that catch the light like underwater treasure, green textured sleeves with Atlantean ridged detailing, and matching scale-print pants. Fiber-filled chest and abs padding gives young heroes the superhero physique (soft and comfortable, not hard plastic), while the attached boot tops mean no hunting for matching shoes at 7:50am on dress-up day.
Perfect For
Book Week & Superhero-Themed Days: Natural pick for comic book character parades, DC superhero story themes, or any classroom Book Week event where kids dress as their favourite heroes.
Halloween & Costume Parties: Instant superhero transformation for trick-or-treating, birthday parties with a Justice League theme, or backyard superhero battles with friends.
Everyday Dress-Up: Durable enough for repeat play — kids love the muscle padding and the trident-wielding possibilities (trident sold separately, but a broomstick works too).
How to Wear It
Pair with comfortable sneakers (the boot tops cover most footwear) and grab a toy trident from the party aisle for full Aquaman effect. For Book Week assembly photos, the long blonde wig and beard set (sold separately) completes the Jason Momoa look, but the costume reads as Aquaman without it.
Parent FAQs
What size should I order?
Check the size chart by chest measurement — the jumpsuit runs true to size through the torso, with the muscle padding adding dimension without tightness. If your child is between sizes, the velcro back closure gives a bit of flex.
Can they wear this over regular clothes?
Not really — it's a fitted jumpsuit designed to be worn directly (maybe over a singlet if the classroom's cold). The muscle padding sits best against the body, and layering underneath bunches the fabric.
How do I wash this? Is the fabric durable?
Hand wash or gentle machine cycle in cold water, hang to dry. The foam elements (gauntlets, boot tops, belt) are backed for durability, and the digital print holds up well to repeated wear — no flaking or fading after a few washes.
Do we need the wig and trident to make this work?
Not essential — the gold armor and green battle suit are instantly recognisable as Aquaman. The wig adds movie-accurate detail for serious fans, and a toy trident makes great action shots, but both are optional add-ons.
Care: Hand wash cold, hang dry. Spot clean foam elements between wears.
