Great to see they can set the pressure in the Uli so it flooooows over the rapids.
On the subject of headgear, I had an epic weekend of SUP in the surf. It was a tad chilly on Saturday and Sunday. On a standard surboard you duck dive under waves. On a SUP on a small beach break I tend to lay across the board and take the occasional bit of white water to the side of the head. It gets a bit cold getting bashed in the ear with cold Bass Strait waves. After a 3 hour session I had a feed and put on a rubber hat and was snug as the proverbial bug.
This morning was perfect sunshine and 3 foot glass. No need of a hat today.
