16.25 ounce heavy weight denim constructed into a Railcar Spikes X016 straight slim fit jean. Made of an American red line selvedge, it should give you years of wear. The denim fabric has a darker classic blue shade of indigo with just a little bit of cotton weft filler showing on the top surface. The feel of the fabric is very stiff and crispy but yet soft to the touch both inside and out. Constructed with hidden back pocket rivets that should break though the pockets after lots of wear, triple stitched seat seams and belt looping for added strength and back and coin interior lined pocketing. 100% cut and sewn at the Railcar Workshop in Monrovia, California on manual and vintage equipment to insure the highest quality. No outsourced subcontractor was used for making the garment.
