I couldn't wait for this to go no sale so I just bought it at regular. Everything I wanted is in this helmet. Lightweight, warm, and looks great! This is one piece of equipment that I own and would not cheap out on.
As for sizing, I tend to wear 7 1/8 New Era Caps, so the Medium fits well. But I think for those who still want to wear a beanie underneath you might want to go a size up or just take out the liner.
