This sweatshirt is built for long-armed freaks like me! I'm 6' 1" with broad shoulders and long arms and a 40-41" chest, and the Medium fits great. The shoulder seams hang off my shoulders, leaving me plenty of room there, but there's no excess baggy material under the armpits. It's roomy through the chest, stomach, and arms without looking slouchy/sloppy, and it fits trim at the waist, with elastic keeping it cinched to your jeans. Plenty long in the body so it won't ride up. The neck is not too loose and not too tight. The material is thick and seems durable enough for years of constant wear. And, as I said, best of all, the arms are plenty long. Nicely done, Parachute!
