Description
xThe thin tie back straps can be adjusted to suit your exact proportions, ensuring the suit stays secure throughout every session. The wide open back is shaped to follow the natural contours of the body, delivering an ergonomic fit that moves with you. Whether you are training for competition or clocking up regular laps, the fit adapts to your needs.
Made from Amanzi Armor chlorine resistant fabric, this suit is built to withstand the demands of regular pool training without fading or losing its shape. Bar tack reinforcement at all stress points adds durability where it matters most. A full front and back lining completes the construction, providing confidence and longevity session after session.
Girls’ sizes 26 and 28 are cut with a medium leg height, offering a more conservative and comfortable fit for younger swimmers. The suit is finished with signature silver foil Amanzi logos on the chest and lower back, giving it a distinctive poolside look. Maximum 50+ UV protection is built into the fabric, adding an extra layer of care during outdoor pool sessions.

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.
