Rash Guard Fabric Guide

Everything that goes into choosing rash guard fabric: fiber blend, stretch, weight, knit and how it affects printing, comfort and durability.

Folded white performance fabric

Short answer: Most rash guards use a polyester/spandex knit (about 80–90% polyester, 10–20% spandex) at roughly 180–220 GSM, because it's durable, quick-drying and takes sublimation. Nylon/spandex is softer and cooler but can't be sublimated in the standard way. Choose by decoration method first, then by feel and price.

The four decisions

1. Fiber blend

Polyester/spandexSmooth, slightly firmFull sublimationLower
Nylon/spandexVery soft, coolDyed colors + print/transferHigher
Recycled polyester/spandexSimilar to standardSublimationSlightly higher

See polyester/elastane and nylon/elastane.

2. Spandex percentage

More spandex means more stretch and compression. Around 12–15% suits most rash guards; compression garments may go to 18–20%.

3. Weight (GSM)

  • 160–180 GSM: light and cool; less opaque and less durable
  • 180–220 GSM: the sweet spot for most rash guards
  • 220+ GSM: durable and opaque; warmer

4. Knit structure

Interlock knits are stable and smooth on both faces; single jerseys are lighter; warp knits are very stable and run-resistant. Ask your manufacturer which knit their fabric uses.

Testing a fabric

Stretch it hard: does it recover? Is it see-through stretched? Wash it five times: has it pilled or shrunk? Sublimate a test print: are colors bright and sharp?

Claims to be careful with

Words like "antibacterial", "moisture-wicking" or "UV protection" are performance claims. Only use them if the mill can provide test evidence for your exact fabric.
