How do you ensure children‘s life jackets and puddle jumpers are safe enough?
At Libra Neoprene, children‘s safety is our top priority. Our kids‘ life jackets and swim vests are designed and manufactured with multiple layers of protection to ensure the highest level of safety. Here’s how we ensure every product is safe enough for children:

1. Compliance with Stringent Safety Standards

All our children‘s swim vests and buoyancy aids are certified to EN 13138-1:2021+AC:2022, the European standard for buoyant aids for swimming instruction. This standard covers:

  • Construction and performance requirements – ensuring the device provides the right amount of buoyancy for the intended user

  • Sizing and fit – proper adjustment to prevent slipping or displacement

  • Marking and warnings – clear safety information visible on the product

  • In-water performance testing – using both test manikins and human test subjects to verify safety

Our products are classified as Class B devices, designed to introduce young swimmers to a range of swimming strokes while ensuring a degree of buoyancy to assist beginners with movement through the water.

2. Small Parts & Choking Hazard Prevention

Children, especially those under 3 years old, explore the world by mouthing objects. That‘s why we take choking hazards extremely seriously:

For products intended for children under 3 years, we apply the strictest requirements, ensuring no small parts that could be swallowed or inhaled are present.

3. Non-Toxic Materials – OEKO-TEX® Standard 100 Certified

Our fabrics, linings, threads, and accessories used in our children‘s products are certified under OEKO-TEX® Standard 100 – the world‘s leading safety label for textile products.

What this means for your child:

  • Every thread, button, zipper, and accessory has been tested against a list of over 1,000 harmful substances

  • Products are free from pesticides, chlorophenols, formaldehyde, allergenic dyes, banned azo dyes, and extractable heavy metals

  • For products intended for babies and toddlers up to 36 months, all textile and non-textile components must comply with the strictest product class I requirements

This ensures that the fabric against your child‘s skin contains nothing that could cause allergies, skin irritation, or long-term health issues.

4. Phthalate-Free & Chemical Compliance

Children‘s products must be free from harmful plasticizers. We ensure compliance through:

  • REACH (SVHC 254+) – Testing for Substances of Very High Concern under EU regulations

  • Phthalates (17P) – All materials are tested to ensure they are free from restricted phthalates including DEHP, DBP, BBP, DINP, DIDP, DNOP, and DIBP

  • CPSIA compliance – Meeting U.S. requirements for lead content and phthalates in children‘s products

  • California Proposition 65 – Ensuring compliance with California‘s strict chemical safety requirements

Every material batch is tested to ensure it meets these rigorous chemical safety standards before being used in production.

5. Buoyancy Performance & Flotation Safety

Proper buoyancy is the most critical safety feature of any life jacket or swim vest. We verify:

  • Minimum buoyancy requirements – Each product is tested to ensure it provides the required buoyancy (e.g., 20 N for garments in the 11-30 kg mass range)

  • Residual buoyancy – Even after conditioning and water immersion, the product retains its buoyancy

  • Flotation angle – Testing ensures the child‘s body takes the correct in-water flotation angle (between horizontal and vertical, feet down)

  • Prevention from sinking – The device prevents the child from sinking further than just underneath the water surface

Products are tested using both test manikins and human test subjects across different weight ranges to ensure safety for all intended users.

6. Anti-Slip Design with Crotch Straps

One of the most important safety features for children‘s life jackets is preventing the vest from riding up or slipping off in the water. Our products include:

  • Adjustable crotch straps – Secure the vest in place and prevent it from sliding up over the child‘s head

  • Dual fixation system – Shoulder straps + waist adjustment + crotch strap for triple security

  • Non-slip shoulder design – Prevents the vest from shifting during active movement

  • Secure fastening systems – Buckles and zippers require at least two simultaneous or sequential actions for release, preventing accidental opening

Independent safety experts recommend that a reliable children‘s flotation device must include shoulder straps + crotch straps for double fixation to prevent upward slipping. Our products exceed this recommendation.

7. Material Durability & Water Resistance

Children are active, and their safety gear needs to keep up. We test our materials for:

  • Resistance to chlorinated salt water – Ensuring the product maintains its integrity after repeated pool and ocean use

  • Resistance of foam to compression – Buoyant materials lose no more than 10% of their buoyancy after conditioning and compression testing

  • Seam strength – Load-bearing components are sewn with synthetic threads that maintain strength even after water exposure

  • Markings and warnings – All safety labels remain legible after exposure to saliva, perspiration, and rubbing

8. Third-Party Testing & Documentation

We don‘t just say our products are safe – we prove it. All our children‘s products undergo testing by independent, accredited third-party laboratories including SGS and Bureau Veritas.

Our test reports cover:

  • EN 13138-1:2021+AC:2022 – Full compliance testing including buoyancy, in-water performance, and construction

  • Chemical testing – REACH SVHC, RoHS, PAHs, Azo dyes, Phthalates (17P), Formaldehyde, Heavy Metals (19 elements), Halogens

  • Physical testing – Seam strength, small parts security, color fastness, material durability

  • OEKO-TEX® Standard 100 – Textile safety certification
