Loved it but... - Rab Microlight Summit Jacket - Men's

This jacket is well-designed with a great feature set. It's light and packable, feels incredibly warm, the pockets are in the right spots with a harness on, the hem/hood adjustments are easy and intuitive, and the Pertex Quantum Infinity fabric is a revelation to see in person. I'd read several other reviews saying that Rab tends to runs small and decided to size up to an XL instead of my customary L and my arms were unfortunately swimming in this thing even with a couple layers on underneath. For reference, I'm 6' ~200 lbs with a 44 inch chest. I was extremely reluctant to return this item and I'll definitely keep an eye out for it in a size L.
