Has anyone seen these. I have quite a few that developed in the last week some time. I usually store my board inside..... but it was outside for two weeks. Always rinsed and dried and in the shade..... but used for about an hour a day in the sun.
Very disappointing for such an expensive board. I am in Mexico with it, so can not take it in to the place I purchased it.
Still love it. Bought a Nalu model so I can deflate this one and put it away until I figure out the problem.
I've never seen a blister on a Naish inflatable and I see the rental ones laying in the sun all day.. every day..
Is the blister under the graphic [sticker].. 
Take many close photos of the blisters with something for scale and send to your shop. You are paying extra with expensive brands for the sponsorized riders and events, the shop margin... and the responsiveness to quality issues.
Small (2mm) can happen and should not be a problem, big (> 5cm) are definitely a factory defect, except opposite to the valve where a blister can develop on all brands.
