The Flat Head Pioneer 3XXX jeans are a 14.5oz denim woven on old shuttle looms. This denim is full of character and famous for its fast, high contrast, vertical fading. Even the pockets are designed to age uniquely, as they are specially double stitched - first with a poly-cotton thread for strength, then with a cotton thread that will shrink, leading to puckering that helps with the fading. This denim is unsanforized and will shrink up to 1.5" in the waist and 3" in the inseam after the first soak. After some wear the waist will stretch back out approximately 1".
The 3005 denim is a straight fit, with a medium/high rise and a slight taper below the knee. This fit gives you ample room for mobility and to fit those engineer boots underneath.
