• Its not especially loose fitting. I wear a medium and I just now tried it on with just a short sleeve T shirt. It fit fine and looked fine. There was some extra room, but not a lot. I'd say you could wear something a little heavier than a T shirt under it, but I wouldn't think you could wear anything too bulky under it. All depends on what you plan to wear under it and if you size up, presumably the sleeves and length will still be right for you. Hope this answered your question. This jacket is a nice shell, average roominess, but especially roomy though.

  • Not a snug fit. I would buy your regular size.

  • Yes. Buy up one size. The arms are generous but it is slim waist. I got a Medium and the waist is most likely 32-33" at the bottom. Great jacket, though. It breathes well, packs up small and has some style to it.

  • Yes, I would suggest going with the larger size.

  • I would buy a size up to wear over a fleece
