• Sourcing Note: These premium materials are sourced directly from the brand owners (e.g., Yamamoto Corporation, Jako, Yulex). MOQ and pricing for these materials are subject to confirmation from the respective brand and may require higher minimums than our standard neoprene.

Detailed Breakdown by Sport

Triathlon Wetsuits — Engineered for Speed & Efficiency

Our triathlon wetsuits are designed to give swimmers a competitive edge in open water. Key features include:

• Quick-Dry Coating — A hydrophobic inner lining that repels water, reducing weight and drag during the swim. This coating also helps the suit dry faster during transitions.

• Easy On / Easy Off Zipper System — Extended back zipper with a long, sturdy pull cord that allows swimmers to remove the suit in under 10 seconds — critical for fast T1 transitions.

• Strategic Buoyancy Placement — Thicker neoprene panels (3mm–5mm) in the chest and legs lift the swimmer's hips and legs, reducing drag and improving body position in the water. Thinner panels (1.5mm) in the shoulders and arms allow for unrestricted stroke movement.

• Hydrodynamic Design — Smooth-skin panels on the chest and back reduce water resistance, enabling a faster, smoother glide through the water.

• Maximum Range of Motion — High-stretch CR, Yamamoto, or Jako neoprene in the shoulder area ensures full arm rotation for freestyle stroke efficiency.

Spearfishing Wetsuits — Built for Stealth & Durability

Our spearfishing wetsuits are purpose-built for the demanding conditions of underwater hunting. Key features include:

• Full Camouflage Sublimation Printing — High-definition, all-over custom camo patterns (reef, blue water, green timber, digital, or your own design) that provide essential stealth. The prints are fade-resistant and permanently infused into the fabric.

• Reinforced Knee Pads — Extra layers of abrasion-resistant neoprene or rubberized patches protect the knees from sharp reefs, rocks, and boat decks during entry, exit, and kneeling.

• Chest Protection — Some models feature a high-density chest pad for comfort and protection when loading spearguns or laying on rocks.

• Hooded Options — Integrated hoods reduce heat loss (up to 30% of body heat escapes through the head) and provide concealment. Hoods with smooth-skin seals minimize water flush.

• Smooth-Skin Seals — Neoprene smooth-skin at the neck, wrists, and ankles creates a water-tight seal, preventing flushing and keeping the diver warm during extended submersion.

• Durable Construction — Blind-stitched seams with pre-bonded glue ensure water-tightness and long-lasting durability in saltwater environments.

Yes. At Libra Neoprene, we fully understand that chemical compliance is a critical requirement for European and North American buyers. We are committed to ensuring all our products meet or exceed REACH (EU) and California Prop 65 standards through our established material sourcing and in-house quality control systems.

Our Chemical Compliance Commitment

1. Material-Level Compliance
All raw materials used in our products — including neoprene (SBR, SCR, CR, limestone-based, recycled), fabrics (nylon, polyester, spandex), printing inks, dyes, zippers, buckles, and threads — are sourced from suppliers who certify compliance with REACH and Prop 65. Our supply chain is built on long-term relationships with verified partners who share our commitment to safety and regulatory standards.

2. In-House Quality Control & Supplier Verification
Our raw material suppliers provide annual third-party test reports for their material categories. We verify these declarations through our own in-house testing protocols (e.g., XRF screening for heavy metals) and maintain strict incoming quality control (IQC) procedures. Non-compliant materials are rejected immediately.

3. Traceability & Documentation
We maintain full traceability from raw material sourcing to finished product. For every production batch, we retain:

• Supplier declarations and material test reports.

• In-house inspection records.

• Production process logs.

How We Handle Customer-Specific Testing Requirements

We recognize that different brands and target markets may have specific testing expectations. To ensure smooth compliance:

• Please communicate your testing requirements at the sample development stage. If you need third-party test reports (e.g., SGS, Bureau Veritas) for specific restricted substances or market regulations (REACH, Prop 65, CPSIA, etc.), we need to know this before sample making begins. This allows us to:

  • Source materials that are 100% aligned with your testing criteria.

  • Plan for any additional testing costs and timelines.

  • Provide the necessary documentation for your compliance files.

• For bulk orders: Routine third-party testing is not conducted for every shipment unless specifically requested by the customer. Our standard practice relies on supplier annual third-party reports combined with our in-house quality control processes to ensure ongoing compliance. When third-party testing is required for a shipment, we will arrange it at the agreed cost and timeline.

Why This Approach Works for Your Business

• Cost-Effective: By aligning testing with your specific requirements early in the process, we avoid unnecessary costs and delays.

• Audit-Ready Documentation: Our traceability system and supplier records provide the documentation needed for factory audits and customer compliance checks.

• Market-Ready Products: Our materials are sourced to meet REACH and Prop 65 baseline requirements, giving you confidence for European and North American markets.

Recommendation for Best Practice

To ensure a seamless compliance process:

1. Define your testing requirements (e.g., which restricted substances, which markets, which test standards) at the sample stage.

2. Share your specific compliance checklist with our team — we will cross-check against our material capabilities.

3. Confirm testing protocols (in-house vs. third-party, frequency, cost allocation) before bulk production begins.

At Libra Neoprene, we are committed to transparency and full traceability. We will provide all available supplier declarations, in-house test records, and, upon request, arrange third-party testing to meet your exact requirements. Let us know your needs early, and we will ensure your products are fully compliant from the very first sample.

 At Libra Neoprene, we operate with significant manufacturing capacity across our vertically integrated facilities. With multiple dedicated production lines and flexible workshop arrangements, we are able to scale production efficiently to meet varying order volumes and deadlines. However, lead times and capacity vary significantly by product type and manufacturing complexity.

Monthly Production Capacity by Product Category

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:

• All small components (buckles, zippers, decorative elements) are tested to ensure they cannot be detached by a child

• Components that could become detached are tested using the small parts cylinder to ensure they do not pose a choking, aspiration, or ingestion hazard

• Attached small parts must withstand a pull force of 90 ± 2 N without becoming detached from the device (per EN 13138-1 requirements)

• All edges and corners of hard and rigid materials are chamfered or rounded with a minimum radius of 1 mm to prevent injuries

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
