I bought this as a I needed a new packable summer jacket and it has massively exceeded my expectations and will probably become my goto spring and autumn jacket.
Although it's lightweight and packs down into its own pocket, it is surprisingly comfortable to wear next to the skin. It has a fully adjustable cuffs and hoods and has managed to keep me dry in two torrential downpours I've tested it in this summer.
The only downside I've found so far is that its a bit "rustly" when used with a day sack.
I'm 6' 1" with a 42" chest and the large fitted perfectly.
