Quick actual weight comparison of the 2014 Neil Pryde Combat 5.3m vs 2015 North Sails Hero ME 5.3m.

Combat -> Claimed = 3.9kg - Actual = 3.884kg
Hero ME -> Claimed = 3.6kg - Actual = 3.573kg

Surprisingly close to the claimed specs and both very similar, hence not too much to report!

A 2015 5.3m2 wave sail coming in dry above 3.5kg is absolutely nothing to report.

I'd be hiding the fact if I wrote the sales brochure.
