After extensive use (50+ days this season), I can say this is one of the best jackets on the market. Waterproofing has never let me down, even on foggy, wet, ice-rind days. Light enough to tour in, deluxe enough to fill the pockets and be comfy in the resort. The added elastic in the hood allows for great head movement in the worst conditions. Stylish, bright colors are great for keeping track of each other in fog and trees. My last Trew coat lasted 7 hard seasons. Trew will continue to be my first choice for outerwear.
I am 5'8" and ~150 lbs and I wear the large size. Originally bought Medium for slimmer fit, but felt my arms were restricted when raising them over my head. I exchanged for large and love the fit. Great customer service made the exchange quick and easy.
