Carhartt® has been making tough-as-nails workwear since the railroad days (seriously, the brand launched its signature bib overalls in 1889). Its Work in Progress label reimagines old-school pieces with a modern vibe, like this cap. Made from 100 percent cotton, it features quilted side panels and cinch cord. - Cotton. - Spot clean. - Import. - Madewell.com only.
