The Longer, Sleeker Wings! The Wing EXT series is specifically designed for taller jumpers (generally 5'10" and up). If you fly small (under 120 square foot) high performance mains but like the security of a larger reserve (i.e.: 79 Velocity and a PD 126) the EXT might be for you.
Please note that this container is NOT for people jumping 150 canopies and over. And also note that this container does not have any extra options, it doesn't cost anything more. It's just a different shape.
