Summary

Carhartt B01 Double Knee is a loose firm-duck work pant that generally matches labeled waist for the intended roomy seat/thigh. Firm duck does not stretch, so between sizes Carhartt’s own chart says buy larger. Some factory lots vary — try on when possible and prioritize waist comfort over chasing a slim look.
