ISUP The Blue Series Tourer SUP. THE YOUTH TOURER 10´6" x 25" x 4. 75" is a great Touring model for kids and young lightweight teenager. The shapes are designed to float and glide easily on flat water. Given the larger length they offer the sensation of speed and a big touring radius. The curve and pulled in tail keep these boards reactive so that they are capable to surf boat wakes and turn fast for even the lightweight paddlers.
