Fabric Story

The ancient meets the industrial to create a radically open yet opaque material. The fundamental differences between knitting and weaving collapse in this Japanese fabric that combines the rugged simplicity of a polyester mesh with the deep character and performance of linen. Open to the air so the skin can breathe, opaque to the eye so the mind can relax and injected with linen's dry touch and beautiful break in to create a remarkable summer fabric.

A super light polyester warp mesh is knitted around a linen weft insertion to combine the durability and stability of polyester with the cool wear and character of a bast fiber. The linen is 59% of the fabric weight and its slubby texture and elegant aging shine through. The polyester warp means it doesn't crease sharply like most linen but instead takes on a gentle waviness that makes it far easier to travel with.


Put this stuff on and it feels like almost nothing, the air just flows over you. Look at it and it’s as opaque as far heavier fabrics, other than in extremely backlit or near face situations you can’t see anything through it. In summertime this is pretty damn close to magic.

Fabric Story

Alpha-D 90 is a midweight (90gsm) insulation with exceptional breathability, allowing for world class warmth without overheating. Alpha was originally designed by Polartec for US Special Forces to use in cold wet conditions, but we find that when used on its own it makes some of the most versatile active use insulation possible.

When worn as a top layer it provides almost completely unrestricted airflow. When in motion or in breezy conditions it barely insulates at all, but when worn under a shell or in calm, still, environments it packs a huge amount of exceptionally soft and cozy warmth. Combined with its light weight and easy packability it makes for an amazing layer for outdoor activities in above freezing conditions. It’s super nice and cozy indoors too, and below freezing it makes an excellent layering piece.
