Frequently Asked Questions

What is Endurance+ fabric?

Endurance+ is Speedo's premium training fabric, made from a polyester and PBT polyester blend. It is 100% chlorine resistant, meaning it retains its shape, colour, and elasticity far longer than standard swimwear fabrics — ideal for swimmers who train regularly.

What is the length of this jammer?

This jammer has a 37cm side seam, giving it a classic mid-thigh length suited to both training and competitive swimming.

What size is currently available?

Only size 10 (AU boys' sizing) is currently available. Select your child's usual Australian swimwear size for the best fit.

Is this jammer suitable for competitive swimming?

Yes. The chlorine-resistant Endurance+ fabric, classic jammer cut, and secure internal drawcord make it well-suited for both squad training and competitive pool use.

How do I care for this jammer to make it last longer?

Rinse in cold fresh water after each use, hand wash with mild detergent, and avoid wringing or tumble drying. This helps preserve the Endurance+ fabric and chlorine-resistant thread for longer.
