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.

The AMANZI Proback One Piece features a medium leg height, which provides a balanced level of coverage suitable for all figures. It sits between a high leg and a more conservative cut, making it a versatile choice for both pool training and active swimming.
The Proback features fixed thin shoulder straps with binding on the chest, straps, and lower back, providing a structured and secure fit. The Tie Back has fully adjustable tie straps which allow a more customisable fit. The Proback has a medium leg height throughout the range, while the Tie Back features a medium leg height in girls' sizes (26 and 28) and a higher leg cut in women's sizes (30 and above).
Yes. The AMANZI Proback One Piece is engineered for both competitive and active swimmers. The thin shoulder straps maximise freedom of movement, the open back follows the body's natural contours for comfort during training, and the chlorine-resistant fabric is designed for regular pool use. It is a training suit rather than a competition suit — for racing, see the AMANZI Acceler8 RIZE range.
The binding on the chest, straps, and lower back reinforces the edges of the suit, providing a cleaner finish, added durability at stress points, and a more supportive feel. It also helps the suit keep its shape over time with regular use.
Rinse in cold fresh water after every session to remove chlorine and salt. Allow to dry naturally away from direct sunlight — do not tumble dry or wring. The AMANZI Armor chlorine-resistant fabric is built for regular pool use and will maintain its colour and shape with proper care.
