I have the lightweight turn out - torrent I think. Has lasted me 2 years so far and have no complaints - they do come up quite small though and that's on a narrow TB.
My lightweight "torrent" is only showerproof, not waterproof in heavy rain/long showers.... No worse than many other more expensive rugs though!!! I agree they do seem to come up small... and it still rubs his shoulders despite pleats (but all his rugs do - so it may just be him!) so he wears a bib! It is wearing well though....
My friend has a heavyweight "harlequin" one and its super - the water just runs off!! Small again though
hateful bloody things - i have a medium weight one, and (aside from not being remotely waterproof) it makes her sweat awfully, and stinks because of it! it also rubs her shoulders - nasty rug!
I have a mw (forgotten the name), thought it was great at first, but soon the front was folding back on itself because there's no velcro, and the lining stuck out the back of the rug. Not impressed
