I have a white HMG Windrider 3400 size M that I would like to trade for a size S in similar condition . Never been used outside (I've only test packed it and walked around the house with it) because I have a SWD pack and kept this one around for my wife. I bough it for $348.34 shipped, willing to sell for $320 shipped, but prefer to trade for a smaller size of the same model http://imgur.com/a/KY2lr
