waxed cotton is great for its intended purpose but absolute crap at everything else. worn them for years shooting where being thornproof is essential but if you dont need to push through brambles while beating on a shoot they are just a heavy sweaty but also cold and clammy expensive coat that stinks.
they have their place but 99% of people who wear them will never be in a situation that requires their main feature of being thornproof and waterproof.
