I have a 100% cashmere RLPL suit that I've owned about 3 years. The cashmere is relatively heavy, and has a certain "fluffiness" I've found in other RLPL cashmere goods. I wear it once every 2-3 weeks from mid-fall through early spring. So far (knock on wood) no appreciable wear or problems with the coat or the pants. The pants do "bag" fairly quickly and need a press more often than my other suits.
