The old and true time tested waxed cotton works the best.
Besides I can pass on to my son and grandson some day. Have any of you seen the latest Filson Catalogue. They have gone Urban Outfitter with all the non hunting and logging clothing that made them famous for the last 100 years. I understand that they have been bought out by Shinola, they make watches. I am really dissapointed that they have abandoned their tranditional market. Also they have switched to imported material, still made in the USA. I am glad I bought my Filson hunting gear 15 years ago, I don't think I could afford to buy the same stuff today.
