Built for the wind you didn't see coming. A 3-layer shell cut from one flight pattern, tested on nothing calmer than a coastline.
A tight ripstop weave stops wind at the surface, so the insulation underneath never has to fight it.
Water gets in through stitching before it gets in through fabric. Every seam is taped, not just the main ones.
A durable water-repellent finish keeps the outer layer beading and light, even after repeated washes.
320 grams, packed smaller than a water bottle — built to be forgotten in a bag until the weather turns.
Measured under sustained pressure, not a marketing minimum. Most storms ask for a tenth of this.
