Sunglasses are a good idea. If you're concerned about them falling off, wear a lanyard. There is a camera mounted on the wing of the glider, so you won't need yours in the air, but a friend might want one to take pictures of you launching or landing. We provide the instruction, guides, life jackets, paddles, and kayaks. Wear a pair shoes you don't mind getting a little wet.
Sandals are fine.
Be sure to wear clothes that you don't mind getting a little wet. You won't be going swimming, but there will be splash off the paddle. Don't forget a light rain coat with hood if it is raining Wear warmer layers for colder days. We would really like to hear from you.
