i looked at the drennan supergrade stuff a couple of years ago , id read the write ups regarding the high level of waterproofness and breathability
went to a tackle shop and was put off by the material being very stiff and noisey
by accident i found a pair of greys gtx over trousers , they may not have the same levels of hydrostatic head as the drennan , im not sure , but they are quite to move around in
ive combined that with a new army goretex jacket , and havent got wet yet , although ive got say they havent been severly tested so far , hopefully thsi winter .........
