661 Sub Gear Long-Sleeve Padded Baselayer
661's high-impact memory foam slowly conforms to the shape of the body, which gives the protective piece a way to eliminate the heavier, air restricting hard caps that have traditionally been used in pressure suits.
661's Power Stretch fabric is a specific polyester blend that helps wick away moisture, and cool the rider with its evaporative properties. The material performs better than traditional pressure suit materials because of its moisture management capabilities.
