Large raincover for a 3 wheeler

[clarkycat]

Any suggestions for a large universal raincover? I have a (now discontinued) 3 wheeler Maclaren MX3 & the usual universal raincovers are too small (I've tried John Lewis & Mothercare). Any ideas much appreciated.

really the urban detour one from mothercare is generous (not their generic one) with the plastic bars in it.

Apollo plastics on ebay?

I had same problem with Jane 3 wheeler as it's wider then average 3 wheeler so ended up having to shell out for their own raincover which is about £15 more than a "universal" one (having bought one and been assured by Mothercare that it would fit, it promptly ripped after about the 3rd use as too small).
Could try Jane to see if it would fit? The good thing about it is that it has a little window flap on the front so you can open it up but keep the rest covered if weather not too wet but you want to keep protection from the wind etc.
