I’ve taken my new Air Glide 410 into a fairly quiet ocean and it performed very well, probably a little less stable than I’d expected as the waves became choppy, but still a great experience. Carting the backpack from car to beach was harder than expected as it’s a pretty heavy package and I can only assume it was a 6ft+ athlete that carried it as a backpack on the promotional video I’d watched online! Also, packed volume was bigger than expected - wouldn’t fit in the car boot.. had to pull down the hatchback seats to get it in.
