An ultralight Darien would make a great urban riding tool (we said to ourselves). We build it just this way, with a tough, HT200 Denier Nylon GORE-TEX® fabric. Although it offers less crash and abrasion resistance, it’s so much lighter that it’s great for camping, skiing, touring, commuting, and general wear. The DarienLight retains every feature of the standard Darien jacket. More comfortable in high and low temps (over 90, below 30) than the regular Darien.
