Billabong has completely revamped the Foil line of wetsuits this year, and they did a really nice job for the price point! This top features 100% superstretch neoprene for excellent flexibility in the water. They beefed up the stretch by adding top of the line "Airlite" superflex to critical pivot points, and eliminating some unnecessary seam panels. Also features: Durable flatlock stitched seams, anti-chafe seams and collar, a short back zipper to ease entry/exit, and a boardshort fastner to minimize "ride ups."
