The PBJ Indigo Trousers are made with deep dyed Indigo warp threads and weft yarns, not garment over dyed, so the indigo threads and yarns are woven together to create a rich, bold, and even color as opposed to over dyed garments which may display characteristically variable hues of indigo over the entire garment. Medium weight 100% cotton twill, one washed, and available in waist sizes from 29"-34.5". Made in Japan. More information
