Recently Carhartt WIP released 3 jackets in permanent waxed cotton. This industrial way of waxing a fabric - instead of a garment - should, according to Carhartt, ensure rewaxing is no longer necessary and hte initial coating will stay on after washing. Not sure but I think waxing a garment is better because it allows you to include the stitching in the process, a known weak spot in any water resistant product. Any experts want to share their thoughts on this?
The best of the three is the Michigan Coat, a traditional work jacket with corduroy collar and four pockets in front. Hidden features are the cotton lining and inside storm cuffs. Available in four colors Carhartt Brown, Cypress, Black and Dark Navy. The black waxed canvas surprised me a bit, because it sounds like Darth Vader raping Indiana Jones, but the outcome is good.
