Guide Gear® Men's Shorty Wetsuit will keep you warmer and more comfortable than you ever dreamed, plus it will last season after season. That's because it's made of two kinds of neoprene. One's a four-way, high-stretch fabric that combines large bubbles for warmth and small cells for density, while the other is made just for flexibility. The result? This Guide Gear Wetsuit. It's warm, beyond comfortable, moves with you and holds up a lot longer than others out there.
