The AERO Series is STORMRs deep breathing mid-weight, ultra-flexible rain gear system. Both the AERO Jacket and Bib deliver superior comfort and all weather performance without the bulk. STORMRs exclusive VAPR Tech material not only breathes deeply, it also allows this system to out-maneuver its competition. Youll realize the significantly extended range of motion the moment you put the AERO Series on. This mid-weight system performs more like a heavy-weight when it comes to severe weather performance. The AERO boasts a 3-layer, DWR treated 20,000mm waterproof and 20,000g/m2 breathable construction. The feature-rich AERO system delivers, YKK AquaGuard zippers, internal neoprene wrist seals, multiple high volume pockets, articulated adjustable hood, knees and seat, internal waist adjustments, as well as the dependability and durability you demand from all STORMR products. VAPR Tech (Variable-stretch Advanced Performance Raingear) is the lighter-weight equivalent to STORMRs Neoprene Core Technology line of outerwear. VAPR Tech offers striking styling, advanced all-weather protection, superior comfort and high-stretch neoprene panels for unmatched mobility in a light-weight shell.
