My cordura pants started to leak at the crotch at the sealing tape,not very pleasant,and my gloves were starting to leak.It was recommended that I use a product called Aqua Proof X08 by COI leisure ( a waterproofer and fabric protector for all canvas products stated on can ) and it worked really well no more leaks, would definitely use it again.Don't know if it is available in the US.
