Summarized by Shop
The JS Thruster Fin is built with the updated new Epoxy Carbon Foam core technology, its wider base provides incredible amounts of instant acceleration, grip, and projection down the line. The constant flex and fast response of the Epoxy-Carbon maintain release out of the lip and through turns. One of the lightest fin sets on the market.

Small (70 kg / 155 lbs), Medium (65–80 kg / 145–175 lbs)
I’ve tried 3 other sets of fins in my xero gravity and these feel the best. They are loose and responsive. They make the Hyfi 3 really wake up.
