I've been looking for a lightweight but warm hoodie. I've finally found it. And it's flattering too. It's got a comfy, loose-ish fit. I go for M or L...if you are the same, get L unless you want it tighter.
I love this hoody. It's lightweight but perfect for wear all year round. The fabric is great for both casual and running/hiking/etc. I usually wear a medium but sized up because I like extra room.
