<size chart> We've always built garments utilizing waterproof/breathable fabrics, but this is our 1st WATERPROOF garment, as the interior shows-off. The fabric--exterior shell with sandwiched breathable laminate and interior mesh-- represents 3-layers of material behaving as 1 while weighing only 95 grams/square meter. That’s equivalent to one of our broadcloth summer shirt fabrics. Yet, the material gives no impression of frailty, it’s a durable semi-matte finished micro-ripstop that kicks ass. A year-round performer as adept over a t-shirt in a summer squall as getting stuck on a chairlift in the middle of a snowstorm. Additional breathability to this 10,000 sq/m rated fabric is provided via hidden laser cut eyelets at armpits—because pit-zips are clumsy, bulky, and generally unnecessary. As purpose driven a jacket as we’ve ever produced. fit: relaxed; layerable content: 3-ply 100% nylon micro-ripstop w/ waterproof breathable laminate + bonded mesh backside, ultra-lightweight 95 gsm, rated 10,000 mm water resistance, 10,000 sq/m/24hr breathability seam-sealed clean finish interior, 100% waterproof garment at extremely light weight dual closure 2-way molded center front zipper and black oxidized snap placket darted and shaped drop tail, +4 1/4" at center back relative to higher stance at center front concealed sideseam zipper hand pockets and high chest pocket care: machine wash cold, no bleach, air dry only, do not iron imported
