RTM Technology
The NSP J3 RTM Fins are an after-market accessory for riders wanting to tune their fin cluster. RTM, or “Resin Transfer Moulding” produces lightweight performance fins, offering great flex, speed, manoeuvrability and responsiveness.

Best used in a variety of all-round surf conditions, the J3 RTM Performance fins (112.5mm) are supplied as side biters with the DC Surf Super X, designed by Dale Chapman.

Suitable for:
Riders wanting to upgrade their NSP Allrounder in Cocomat or Elements construction to a fin with a little more bite.

Best used in a variety of all-round surf conditions, riders whose style is back-foot heavy will benefit from the added bite and their board will slide less and slash more with RTM fins.

A pair of J3 RTM works well in combination with the Wave 6 Centre Fin, in simple thruster setup on surfboards or in combination with a J5 (115mm) or J7 (120 mm) centre fin.

Available in two other sizes; J5 (115mm) and J7 (120 mm)
