Typically this packable vest category has been dominated by lightweight ripstop fabric pieces that provide good wind and spray resistance but a whole lot of flapping and noise. Our goal was to give you everthing you need without sounding like a flag in a breeze. We engineered a strecth fabric that conforms to your body providing a soundless ride while providing wind resistance. To resist spray we treat the front panel fabric with a durable water repellant coating while leaving the back panel fabric untreated to increase breathability. The vest balls up inot a fist size ball.
