The S-1 Pro showcases the pinnacle of SEVERNE’s construction technology: the complete sail including the batten pockets are welded CarbonFusion.  This creates a smooth, stitchless sail from the back of the mast sleeve to the leech.  Eliminating the thousands of micro-holes created by the stitching has multiple benefits;

/ Instant response.  Less stretch and movement under load
/ Stronger
/ Smoother

The S-1 Pro is the ultimate manoeuvre-oriented wave sail.
