Hi,
I've been looking into making myself a pair of rain pants, but I'm not sure which fabric I should get. The two big outdoor fabric suppliers here seem to be
http://www.profabrics.co.uk
and
http://www.pennineoutdoor.co.uk/
For WPB fabrics in black, profabrics offers Skylon, which they say is similar to Pertex (not sure which kind). Pennine's WPB selection is even more vague–names like P42, P32, etc. I'm reluctant to order any of these without some advice first. I've heard Pertex soaks through pretty quickly as well.
Should I just go with something not breathable to be safe?
Are there any other fabric suppliers in the UK I should look at? (Or in Europe I suppose)
Thanks for your help.
