Dynamo Junior is a girls’ one-piece with comfortable wide straps and a moderately open back. Its construction suits swimming lessons and training where a stable fit matters more than narrow, highly open straps. The leg cut offers medium coverage.
The older model uses classic MaxFit made from 80% polyamide and 20% elastane, allowing the suit to stretch with movement. This is not the newer Eco version. Choose junior sizing from arena’s body measurements for an accurate pool fit.
