Swimming Rash Guards

Swimming Rash Guards — Manufactured for Chlorine, Salt Water and Real Wear

A rash guard has one job that matters more than any other: to stay intact where it meets water, sun and skin. Synthetic chlorine, salt crystals and continuous moisture destroy ordinary spandex knits within a season — the fabric hardens, the elasticity dies, the print lifts and the shoulder seams begin to chafe.

We manufacture custom swimming rash guards for swim brands, surf labels and resort-wear collections, using 85% recycled polyester (rPET) + 15% spandex finished with a professional anti-chlorine and anti-salt treatment. Every style is built on full flatlock construction and integrated sublimation printing, so the garment you approve as a sample is the garment that arrives in your customer’s hands six months later.

  • 01

    UPF 50+ Protection

    Blocks the ultraviolet exposure that causes sunburn during open-water swimming, surfing and beach programs.

  • 02

    Anti-Chlorine & Anti-Salt

    The fabric will not harden, lose elasticity or fade after repeated pool and seawater use — the most common failure mode in cheap rash guards.

  • 03

    Anti-Chafe Flatlock Seams

    Full flatlock across shoulders, sides and torso dramatically reduces board rash and friction from kickboards and surfboards.

Construction Details

These are the build specifications that define our rash guard output. They can be adjusted to your price point, but we do not recommend compromising on the first four.

  • Recycled polyester-spandex main fabric with professional anti-chlorine and anti-salt-resistant finishing, retaining elasticity through long-term immersion in pools and seawater.
  • Ergonomic streamlined slim cutting that fits close to the body, reducing water resistance during swim strokes.
  • Full flatlock seamless stitching across shoulders, sides and torso — effectively eliminating skin friction rash from prolonged board and water-flow contact.
  • Elastic binding neatly finished on neckline, cuffs and bottom hem for a stable fit that will not roll up or slip underwater.
  • Optional half-zip front placket for easy dressing and temperature adjustment in open water.
  • Integrated full sublimation printing — patterns dyed into the fibre inherently, with no peeling, cracking or fading under long-term water washing.
  • Tagless heat-transfer inner neck label to remove scratch irritation in wet conditions.
  • Eco-friendly low-toxic finishing — no harmful chemical substances dissolved into water, safe for human skin and the marine environment.
  • Optimised nesting layout cutting that reduces fabric waste during production and supports carbon-neutral certification.
  • High-density weave structure that resists snagging and deformation through daily swimming use.

Performance Features

  • UPF 50+ ultraviolet protection to prevent sunburn and long-term sun damage during outdoor sea swimming and beach activity.
  • Professional anti-chlorine and anti-salt treatment — the fabric keeps its hand-feel and shape after frequent pool and seawater exposure.
  • High 4-way stretch for unrestricted arm strokes, kicking and twisting movements while swimming.
  • Smooth anti-chafe flatlock seams that greatly reduce board rash and friction irritation against surfboards and kickboards.
  • Hydrophobic quick-dry property — drains excess water rapidly and dries quickly after leaving the water.
  • Streamlined tight-fit design that lowers water drag for a smoother swimming experience.
  • Permanent sublimation graphics that stay vivid under prolonged underwater conditions.
  • Skin-friendly eco processing without irritant residues — suitable for adults and children in long-duration close-fitting water sports.
  • Lightweight and compact — folds easily into a swim bag for travel and resort retail.
  • Sustainable recycled polyester raw material, producing an ocean-safe swimwear story your marketing team can actually substantiate.

Frequently Asked Questions

How long will the print actually last?

Sublimated graphics on our rash guards are fused into the fibre, not applied to the surface, so they do not crack or peel. Under normal pool and seawater use they outlast the garment itself. We can supply colourfastness-to-chlorinated-water test reports if your buyer requires them.

Do you offer kidswear sizes?

Yes. Kids’ rash guards are one of our higher-volume lines, with age grading and safety-compliant trims. We can also produce matched adult and kids’ styles for family or school programs.

Can I add a half-zip to an existing design?

Yes. The half-zip front placket is an optional construction we add at pattern stage. It changes the pattern and slightly increases cost, so tell us at sampling rather than after bulk approval.

Is the recycled content certified?

Yes. Our recycled polyester stream is covered by the Intertek GRS 4.0 scope certificate, and the base knits are OEKO-TEX® STANDARD 100 certified (Certificate No. BJ015 242844, TESTEX AG). Certificate copies are available for your product documentation.

What do you need from me to quote?

Ideally a tech pack, a reference sample or clear reference images, plus your target quantity and fabric preference. If you only have a design idea, send that — our team will propose the construction and price it.
