NeroFit Jammers are sized for both youth and adult swimmers.
Youth sizes roughly translate to your swimmer's age. For example, an average 10 year old will fit in the size 10 Jammer. View the size chart to confirm height and weight ranges before purchasing. Adult sizes start at 22 and are based solely on height and weight. Click here for a downloadable PDF explaining fit and care.
IMPORTANT
The NeroFIT line of products, including this model, has been discontinued and it is sold as a final sale — no returns or exchanges are accepted for this item.
The NeroFIT has been replaced by a newer version featuring an upgraded textile, currently available only through the Blueseventy USA site. Unfortunately, this updated model is not yet available in Canada.
That said, the NeroFIT remains an exceptional performance suit — fast, technical, and race-proven. It’s a favorite among competitive swimmers and still delivers outstanding results.
