Here’s a last-chance alert for all the textile nerds out there (myself included). Loop & Weft designed a 100% cotton thermal fabric so difficult to manufacture that the factory gave ’em the ‘ol “No Mas” on any possibility of ordering another batch. While the self-imposed tagline of “Best Knitwear” will likely be debated by some, their drive to provide just that is something that can’t be debated, something their factory could surely vouch for.

The vintage-inspired military thermal was built with that aforementioned knit fabric and has a slim fit, utilizes cotton thread sewing construction with 4 needle flat seams, tagua nut buttons, and was washed down to remove shrink. Cutting no corners, the unsanforized Kibata cotton fabric used on the button tape is the same material used for pocket bags in premium Japanese jeans. But the real kicker here is that fabric, which looks like no other thermal this author has come across—and unless things change this is your only shot at it.

Available for $125 at Okayama Denim.
