Outlier warp-knits this blend in Japan at 59% linen to 41% polyester, chasing a specific trade-off: air moves through it the way it does through mesh, but the weave stays opaque enough that it never goes see-through. The polyester content also changes how it wrinkles — instead of the sharp creases pure linen holds after a flight, it settles into soft waves that relax out on their own overnight. The pants run $198.
