Thanks, back from Cape Town, they shut the beaches unfortunately, but had quite a few good wing days and some good windsurfing in December, now back in lockdown and snow..:-)
so according to the ION board bag finder info I have:
Bag should be the SUP/Wingfoil Core Stubby in size
8´10 x 31,5
270 x 80
Sounds a bit long obviously, but that is the best we can do for now.
