Kids Life Jackets, Vests & PFDs
Jetpilot kids life jackets, every vest approved to standard — the Cause Infant at 100N (ISO-12402-4) for under-30 kg riders, Cause Kids and Cause Youth as 50N (ISO-12402-5) buoyancy aids, and the X1 Boys/Girls CE impact-standard wake vests, for 30–50 kg. All youth vests have crotch straps, sized by weight not age. Choose by certified weight class on the inside label.

Jetpilot kids life jackets cover infants, kids, and youth riders with age-appropriate buoyancy class and sizing. The range starts with the Cause Infant at ISO-12402-4 (100N) for under-30 kg riders — infant safety regulation requires turn-the-face-up performance regardless of activity. From toddlers up through pre-teen riders, the Cause Kids, Cause Youth, and X1 Boys/Girls series are 50N buoyancy aids (ISO-12402-5) sized by weight class, with crotch straps the adult range doesn't have. Choose by weight, not by age — kids' sizing is bracketed by kilograms, not birthdays.
Buoyancy class by age and weight
European safety regulation maps buoyancy class to weight, not age. Under 30 kg / infants up to ~3 years: 100N life jacket (ISO-12402-4) is mandatory because young children cannot self-right after impact. The Cause Infant is the dedicated Jetpilot 100N model, with high collar and crotch strap. 30–50 kg / approx. 4–12 years: 50N buoyancy aid (ISO-12402-5) is appropriate because the child is a competent swimmer; the Cause Kids and youth-cut X1 series fit this band. Over 50 kg / teens transitioning to adult: a small adult vest (X1 men's or ladies' XS) often fits better than the youth cut. Confirm the certified weight class on each product label before buying.
Sizing: weight first, chest second
Kids vests are sized by body weight, with chest measurement as a secondary fit check. Weigh your child first, then measure their chest at the widest point. Compare both to the size chart on each product page. A correctly fitted kids vest stays put when an adult pulls upward on the shoulders — it must not ride above the chin and must not be loose enough for the child to slip out. Crotch strap is non-negotiable for under-50 kg. The strap loops between the legs and prevents the vest from riding up on impact, which is the most common life-threatening fit failure on children. Size up only if the child is at the very top of a weight band; do not buy "to grow into."
How long can my child wear the same vest?
A kids life jacket is outgrown when the child crosses out of the certified weight band, or when the vest becomes too tight at the chest. Both are quicker than expected — most growing kids cycle through 2–3 vests between infant and youth-adult transition. Replace earlier if the foam shows compression marks or cracks, the straps fray, the buckles fail, or the ISO label becomes unreadable. Storage matters: heat, sun exposure, and chemical contact (sunscreen, fuel) all shorten the life of buoyancy foam. A used hand-me-down vest is acceptable only if (a) the previous owner was a similar weight class, (b) the foam is uncompressed, (c) all straps and buckles are intact, and (d) the ISO label is readable.
Activity-specific cuts
The Cause Kids and Cause Youth series are front-entry, neoprene-comfort designs for general watersport use — kayak, SUP, behind-the-boat, learning-to-ride. The X1 Girls and Boys series add reinforcement for active jetski and wakeboard use. The Freeride Boys/Girls Youth Ecoprene line uses the eco-conscious neoprene variant. Brand names notwithstanding, all 50N kids vests share the same certification class and core safety features; pick by colour and fit preference once the weight class is correct.
Frequently asked questions
What's the right life jacket for a 1-year-old?
A 1-year-old needs a 100N infant life jacket (ISO-12402-4), not a 50N buoyancy aid. The Cause Infant range covers 5–15 kg or so. Confirm the certified weight band on the inside label before any time on the water — under-30 kg children cannot self-right and the 100N class is regulated, not optional.
50N or 100N for kids?
Under 30 kg: 100N (Cause Infant). Over 30 kg up to 50 kg: 50N is appropriate (Cause Kids, Cause Youth, X1 Boys/Girls). Above 50 kg: small adult vest. Buoyancy class is set by weight, not age — a tall light 4-year-old may still need 100N, a sturdy 8-year-old may already be in the 50N band.
How do I know if the vest fits properly?
Two checks: (1) hold the shoulder straps and pull straight up — the vest must not ride above the child's chin, and (2) check arm mobility — the child should be able to raise their arms fully overhead. The crotch strap must be threaded and tight enough that you can fit two fingers underneath. Loose vests slip off on impact; tight vests restrict breathing.
Does my child still need a life jacket if they can swim?
Yes. A buoyancy aid is for active swimmers — but unconscious wearers need 100N face-up turning, and even competent children's swimmers can be knocked unconscious in a fall. The fundamental difference between adult and kids requirements is that European regulation does not allow under-30 kg children to wear 50N at all, regardless of swim ability.
Can I buy a vest "to grow into"?
No. An oversized kids vest will ride up on impact, slipping over the head and exposing the airway. This is the single most common life-threatening fit failure on children. Buy for the current weight, replace when the child crosses out of the certified band. Vest costs are far lower than the consequences of an oversized fit.
