    Awesome shop! Very friendly, quick response time and very helpful in making all of my selections. Goes above and beyond offering tips on the item purchased. If they don't have it he will find it. Always a great attitude that makes me more stoked to get in the water. I highly recommend this shop!

    I’ve placed 5 or 6 orders with Wind-NC and had a great experience every time. Super helpful, responsive and knowledgeable. He takes the time to help his customers. I’ve ordered from most of the main windsurfing shops in the US at various times over the years and Wind-NC has been a step above.
