If you sweat in Gortex, you have too many clothes on! If you want to stay dry, then Gortex is the way to go!. Lot's of different coat maker's use the gortex waterproof membrane and coat quality differ's, but the gortex is still waterproof. If you don't mind Army Camo pattern, find an ex army shop and ask for a Dutch Camo Gortex Coat and Trouser's. I bought them, coat was £48 , Trouser's were £38. I stay completely dry however much it rain's while following hound's.
