Mission Workshop Sans Microlight Rain Jacket M Toray 3L Waterproof 5.6oz 🌧 Mission Workshop — The Sans 🌧 Microlight Rain Shell | Black | Men's Medium Advanced Projects | 5.6 oz | Toray Japan 3-Layer | Fully Seam Taped The Sans — Mission Workshop's Advanced Projects rain shell and one of the lightest waterproof jackets in the world at 5.6 ounces. Unlike most ultralight shells, this is a true 3-layer garment built to last for years, with stretch, an adjustable anatomic hood, and a full-size zippered chest pocket. It functions as a rain jacket without looking like one. Retail price: $475. 🧵 The Fabric: Toray Entrant 3L The shell is a 50 g/m² 3-layer fabric made exclusively for Mission Workshop by Toray in Japan, built on Toray's Entrant microporous membrane. The numbers are top-tier: a 30,000mm water column rating and 30,000+ MVTR — highly waterproof and highly breathable at the same time. The fabric began as an experiment at Toray's mill; Mission Workshop worked with them through lab and field testing to bring it to production. Toray is one of the biggest names in advanced materials anywhere — a Japanese giant founded in 1926, the world's largest producer of carbon fiber (the Boeing 787 flies on it), and Japan's largest maker of synthetic fiber. If you own Uniqlo HEATTECH or AIRism, you're wearing Toray. Patagonia's Torrentshell 3L rainwear runs on a custom Toray membrane, and Toray's Dermizax shells appear in ski and moto gear from Descente and Da
