This waterproof/breathable, cross-seasonal trench coat is fully seam-sealed for maximum weather protection. It's also windproof, and the lightweight ripstop polyester shell has a durable, water-repellent finish that causes moisture to bead and roll off rather than soak into the fabric. A button-in insulated liner provides essential warmth when the temperature drops.Perfect For All Occasions And Weather"Great for rain, and toasty warm for cold weather. When the insulated lining is detached, it becomes a light jacket. And it's dressy enough to wear as a wrap for going out to dinner."–longtallsal
