I for one would rather have something that looks a little odd (to our modern sensibilities) and functions well, than deal with the annoyance of clothing that doesn't function properly. Having to constantly adjust something, or having clothing or gear rub or pull in a weird way while trying to walk, sit, kneel, step over logs, or whatever movement is required, is a much larger bother than looking a little funny. Most of us aren't putting this clothing on and standing still in a pose like a model.
Let's face it, to most folks, we look funny dressing in this stuff anyway.
Part of the reason I have come to realize I like my knee breaches better for hunting than pants, in some ways, is not having them pull against my knee when I step over something or climb a hill, not having the material at the bottom flapping, catching brush, or rubbing against the material on the other leg making noise.
