3 Key Features

EnduraSoft Fabric

Speedo’s EnduraSoft fabric is engineered specifically to withstand repeated exposure to chlorinated pool water. It retains its shape, colour and softness far longer than standard swimwear materials. This means the jammer keeps looking and feeling great across an entire season of lessons and squad sessions.

Four-Way Stretch

The four-way stretch construction moves with young swimmers in every direction, so nothing restricts natural movement in the water. Whether your child is pushing off the wall or kicking through a length, the fabric adapts to their body. Comfort is consistent from the first length to the last.

Pilling Resistance

Pilling resistance is built into the fabric, keeping the surface smooth and tidy even after heavy use. Rough pool steps, floats and kickboards can all cause ordinary swimwear to deteriorate quickly. This jammer holds its finish so it continues to look presentable throughout the swimming season.

Why Buy from Allens Swimwear?

A Family Business Built on Swimming Since 1976

Allens Swimwear is a family-run business founded in 1976 by Dennis Allen and his daughter Linda Beal. It started from a genuine need. “With 2 swimmers in the family it was often difficult to find the right kit, so dad and I took the plunge and started selling to local swimmers at our local pool in Kingsbury out of a suitcase and we’ve never looked back.” Today, Linda, her husband Richard, and three of their children Danny, Will and Jenna still run the business together. The suitcase may be long gone, but the founding principle of helping swimmers get the right kit remains exactly the same.

Fit Notes — Speedo Global Fit Infants & Little Kids

For girls, always use the chest measurement as the primary guide when selecting a size. Use height as a supporting reference, particularly for the youngest sizes.
For boys, use the waist and hip measurements as the primary guide. Both should fall within the same size — if they suggest different sizes, use the hip measurement to decide.
Age is shown as a guide only — babies and young children grow at different rates, so always measure and compare to the size table rather than selecting by age alone.
For girls, if chest and hip measurements suggest different sizes, choose the size that fits the chest. The chest is the hardest area to adjust in a one-piece swimsuit.
Speedo infant swimsuits are designed to fit closely and securely — they feel firmer than a regular fitted top to ensure the suit stays in place in the water.
Speedo swimwear is made from chlorine-resistant fabrics that ease slightly with wear — do not size up based on initial tightness.
Rinse in cold fresh water immediately after every use. Do not tumble dry, iron, or dry-clean.

Frequently Asked Questions — Speedo Infant & Little Kids' Swimwear

Measure your child's chest, height, waist, and hips against their skin with a soft tape measure. For girls, use the chest as the primary guide with height as a supporting reference. For boys, use the waist and hip measurements as the primary guide. Age is shown as a guide only — always use body measurements to confirm the right size.

We recommend sizing to your child's current measurements rather than sizing up for growth. Swimwear that is too large will not stay in place in the water and may be unsafe for young swimmers. Speedo's chlorine-resistant fabrics ease slightly with wear, so a correctly fitted suit will remain comfortable over time.

For girls, use the chest measurement to decide — if the chest falls between two sizes, choose the larger size. For boys, use the hip measurement to decide. For very young children, height can also help confirm the right size. Speak to a member of staff at Allens if you are unsure.

Yes. Speedo infant and toddler swimwear is designed for regular pool use and made from chlorine-resistant fabric suited to frequent swimming lessons. A well-fitted suit that stays securely in place is particularly important for young children in the water.

Speedo infant swimwear sizes do not directly correspond to standard babywear or clothing sizes. Always use body measurements to select the correct size. The age equivalents shown in the table are a secondary guide only — babies develop at different rates and the same age can correspond to significantly different body measurements.

Most public pools require babies and toddlers who are not yet toilet trained to wear a swim nappy under their swimsuit. Speedo offer a range of reusable swim nappies designed to be worn under their infant swimwear. If you need guidance on sizing swim nappies alongside a swimsuit, speak to a member of staff at Allens.

Rinse in cold fresh water immediately after every use to remove chlorine, salt, and sunscreen. Hand wash gently with a mild detergent if needed. Do not machine wash, tumble dry, iron, or dry-clean. Store flat and dry, away from direct sunlight.
