A gift for my boyfriend...He's 5'11, 150lbs, 32in waist, typically wears M/L. I bought and XL because the description says model is wearing M with a 30in waist, and outer layer is 100% cotton. Boyfriend loves the fit. It's a really nice, light coat, perfect for spring and enough room to wear layers underneath if you wanted. Happy with the purchase. Processed and shipped within 4 or 5 days.
