it is good, hovever with the Koga Miyata i have to remove the front pannier rack to use it. Its also basically a single skin so you do get condensation - especially with a snoring farting jack russell hot water bottle. theres also no room for kit, so i pitch a basher from the saddle of the bike to the trailer on its end with the hitch pointing up in the air to make a bivvy to put the saddle bags under
I must be mad
