I would like to add that I have a 34 inch chest and was wondering what size should I go for? The small would make the most sense ,but I think the medium or large would be better?
You would be swimming in a large! If you like a more baggy fit and the ability to fully cover your hands in the sleeves, then a medium will do. But if you prefer a hoodie to fit more like a t-shirt then get a small.
