When I saw your topic I was all set to say that all rainwear I have ever seen or tried was noisy, but the quietest I have come across is the Browning Goretex rain stuff I now have. Then I read the message and, well, this is expensive clothing - and is not all that quiet. Maybe some of the quieter dry weather garmets would work if they were treated with some sort of temporary waterproofing. What happens if one soaks a quiet outfit in one of these spray waxes that they use in a car wash? (Ihave never found any of the permanently waterproofed cotton materials to be all that quiet either, and they usually are heavy and uncomfortable.)

Come to think of it, if it really is raining, does it matter the noise one makes when drawing a bow? Doesn't the rain itself make a lot of noise falling to cover? (Where I hunt it rarely rains during hunting season.)
