Hello,
The new Petzl oversuits (yellow PVC) are now on sale in France, they're supposed to be better than the Meanders, so it might be worth waiting for a bit till we get them too.
I've got a heavy duty Warmbac at the moment, it's probably about as strong as you could realistically build an oversuit. The fabric has now worn out, but the seams are still intact and the rips don't appear to have spread which is a definite sign of quality. The sizing is rubbish though! They seem to make them wider rather than longer, hence if you're tall you have to get a massive size, which is rediculously baggy. I'm 6'2" and have to wear a XXL, though it still only just reaches the top of my wellies :evil:
Like others have said the cordura ones are best for dry jagged caves, but the PVC ones are better in wet and windy conditions. Personally I'd go for a PVC job if you intend doing any of the latter.
The only ones I know of to definitely avoid are the red Beaver ones because the stitching comes apart very quickly.
The only other thing is to make sure you can move around in it when you buy it, i.e. you can crouch down, reach up, crawl etc. You will look quite stupid
, but it's well worthwhile.
Cheers,
George.
