Along with our Graded Sizing, the Coaster features a Thin Back Design offering more coverage and ensuring compatibility with any seat back style. The Coaster is perfect for use with boats that feature a higher seat back, but are right at home in a touring boat with sprayskirt. The Coaster is designed to have a slightly larger footprint, which helps to distribute flotation over a wider area. The result is a thinner profile that provides more mobility and comfort, while reducing interference with today's taller seat backs. For sit-on-tops, the vest can be worn lower on the torso for maximum back coverage against tall seats. For touring boats, simply adjust the shoulder straps so that the vest rides higher on your torso, and eliminates interference with your sprayskirt. Along with providing a great fit, the Coaster also features multiple pockets that will hold a beverage, your sunglasses, and other small items.
