We’ve been wearing these Air Knit Tees ($38) since Flint and Tinder’s head designer gave us the first samples, and they’re the softest, best-fitting shirts we’ve ever worn. The secret sauce?

100% long-staple Supima cotton that’s grown in California and knit with a new advanced technique called “Baby Jersey” to make a luxurious and airy fabric.

It’s why these Air Knit Tees look and feel more like cashmere than your standard cotton, and why they’re slowly starting to steal airtime from the button-downs and sweaters in our closets. Long live Supima.
