Fly Racing Street Armored Tech Hoodie - Men's Motorcycle Jacket with CE Armor, Large Size - Perfect for Urban Riding & Street Bike Protection

I am 5'-10" and 150lbs with a 31" waist. I originally bought the Medium, but it was a little too snug for my liking, almost tight really with just a shirt underneath. The large fits much better with just a little room underneath for a hoodie if I need it, but still fits well with just a T-shirt underneath (doesn't look baggy at all). The armor takes up some of the space inside, so I assume that's why the large fits so well for me, I typically wear mediums in every other jacket I've ever owned. Also, this isn't like a sweatshirt really at all, it's more like a soft shell jacket. Also, the hood is removable and I don't really see a need for it unless you are going to be socializing with your helmet off. It does keep the wind out really well, and is actually pretty warm. It has been great on my morning commutes when the temps have been around 40-50 degrees . Also, it's a very stylish jacket as well, I have had a few compliments on it already.
