The 5.11 Tactical™ 3-in-1 Parka (A.k.a 3-in-1 Outershell Jacket) is uniquely engineered with dual layer resistance to moisture penetration while allowing moisture vapor inside the jacket to pass through the 100% nylon face for maximum breathability. In short, this jacket works twice as hard as any other jacket to keep you dry. Combine its waterproof/breathable abilities with a fully taped seam construction and you have a tactical performance jacket that like you - always gets the job done.
