Get a sweatshirt. Hoodies fucking suck and are nasty.
They're comfy and convenient, and let me have an easier time controlling my body temperature.
What kind of sweatshirt would you even go for that doesn't look dorky though?
I have black sweatshirts. They look like hoodies not sweaters. Hoodies have neck seams from the hood that make you look like a turtle and they don't distribute heat right.
