I agree on the using them hard, or at least as intended and not having to worry they won't hold up- at least the 264,265 and 266 and small field bag...Mine see rain, dirt, mud, snow some blood and get tossed in the back of the truck or quad, accompany me to the sporting clays range, upland fields, waterfowl blinds and in my opinion look better for it. If they did not hold up i'd have to move on, but with all that hard use I've never had any issue. Every now and then I clean them up and they look great, and twice a year I treat the leather.I can appreciate that sentiment. But I kinda like the idea of using them hard and letting the scuffs and stains come as they may.
Okay, not so much with my tan or smaller bags like my Sportsman but certainly with the 242 and DEFINITELY with the heavy tin moss duffle. I have checked them both for years and they keep looking better (to my eye). The 34oz heavy tin material is extremely resistant to stains and scuffs - it is as incrementally tougher from the twill as the twill is from the regular tin cloth.
