Actually the Fender covers I have are Nylon woven fabric with a vinyl coating on the inside. The seam edges are also a nylon sewn edging. Its better than just plastic and the big bold Fender logo alone is worth at least half the cost of the cover. Short of ordering a flight case there are hard sided covers you can get from other companies for more protection. But for careful transportation and as a dust cover I dig it!

Well, it's plastic, it's black and it covers your amp to protect it from getting crude on it. Features? Did I mention it's a cover. Oh and it's got a nifty white fender logo on the front, can't go wrong for an Andy Jackson.
