Kids Jammers
Swim jammers are knee-length swim shorts, and ours are made for children who still need a bit of extra support in the pool. Each pair has a snug waistband and medical-grade silicone seals around the thighs, so if there's an accident, it stays inside the jammer and your child can carry on enjoying their lesson.
We make them for children aged 2 to 8 who need fecal leak protection but feel they've outgrown a swim diaper. From the poolside, they look like any other sporty swim shorts, which can make a real difference to a child's confidence in the water.
Which Jammer Swimsuit Suits Your Child?
For toddlers aged 2 to 5, our Splash Jammers come in a run of prints, Shark Reef among them, plus a plain navy pair. They're made from 1mm neoprene with UPF50+ sun protection, you don't need anything underneath, and most US swim schools accept them in place of a Happy Nappy™ swim diaper once a child is older.
If your swim school asks for a double-layer system, the Splash Jammer Duo™ is the same jammer with a silver-lined inner layer added, in sizes from 3 to 6 years. It won Gold for Best Potty Training Product at the Organic Baby Awards 2024.
For older kids, our Child Jammers run up to 7 to 8 years in unisex navy colorways with no prints. They're the closest thing we make to youth swim jammers, and they look exactly like regular swimwear.
Sizing and What to Pair Them With
The seals work best when the jammer sits snugly at the waist and thighs without leaving deep red marks, so we size by measurement rather than age. Each product page has a size checker that takes your child's waist and thigh in inches, and our swim jammers size chart has the full figures if they're between two sizes.
If you're getting ready for lessons, our Splash Jammer™ bundles pair toddler jammers with a float jacket or a rash vest.

Kids Splash Jammer FAQs
Most swim jammers are knee-length shorts made for racing and training, but ours are made for leak protection. A snug waistband and silicone thigh seals contain solids, so a child who needs that support can swim confidently in something that looks like ordinary swim shorts. They don't hold urine, and they aren't designed to.
For a child who needs fecal leak protection, yes. Our jammers are reusable and need no disposable swim diaper underneath, so one pair replaces a lot of disposables over a season of lessons. Most US swim schools accept them, and your child gets to wear swimwear that looks just like their friends'.
Neither wins across the board. Swim briefs give the least coverage, while jammers run down to the thigh. For leak protection the jammer cut wins, because the thigh is where our medical-grade silicone seals sit, keeping solids safely inside.
It depends on what your child needs them for. The best swim jammers for leak protection have a snug waistband, a medical-grade silicone thigh seal and swim school approval, and our Splash Jammer Duo™ adds a silver-lined second layer for pools that ask for a double-layer swim diaper.
