No experience with JR Roscoe Co. but I have tried and own at least 3 or 4 others. Could NEVER warm up to them, uncomfortable (always pulling) and you can't remove your jacket if you get hot or need to have free movement. I actually sold a few recently and the only ones I have kept are Military types for Military pistols and revolvers. Quite honestly, I will more than likely sell those one day as well since when I do try to wear them it never lasts long as they are still uncomfortable.
