So the gf got me some extreme flex jeans from American Eagle for Christmas. Whatever fabric they combine in these things makes you feel like you can run a marathon in them. Not only the waistband has great flexibility but everywhere else does. Come in all different cuts and colors. Makes ccw easily more comfortable because imo nothing is more annoying that that waistband digging the gun in my side. Just last week the were on sale for 19.99 ea. Not sure if still on sale still. .....End of PSA
