Description There’s nothing too flashy about the Flash tube, and there’s no need for it either. Straightforward and basic by design, the Flash does everything a good tube should, but just a little better. With its incredibly stretchy, soft, and moisture-wicking blend of polyester and elastane, one size fits all and that one size pretty much does it all, too. Perfect for protecting your neck from either the heat of the sun or the cold of the wind, the Flash is made to improve comfort on just about any ride.
