I wear, and ordered an xl, but this thing fits like an xxl. Doesn't seem too warm, but that may be because it's so big. Instead of hoodie I'd wear out and about, it's been relegated to a lounge around the house hoodie.
The hoodies are awesome! They are very similar to Under Armour hoodies but they are actually softer. The arm pocket is bigger than I expected and the kangaroo pocket has zippers on both sides for quick access to a concealed firearm. The only problem is that I can't decide which patch I want to order for the right arm!
