I'm female so ordered in purple. I'm a 22 1/4 helmet size but ordered in large. Pretty decent fit, would say runs a tad small as was quite snug over forehead. Before breaking in, the snugness over my forehead actually pressed my brow down and I hated it, but as usual, the lining relaxed with wear. This helmet probably favors the 'earth' shaped head rather than a longer face. The quality of the shell and removable lining and neck seems pretty decent. I'm impressed with its light weight too. I'd give it 5 stars IF it was vented. In TX's summer heat, any non vented helmet can feel oppressive. But, perhaps from my female vanity, the overall look of the helmet won out over more practical features. DK has this priced right, so I am happy with my purchase. The racing stripe adds visibilty...you can see this one coming!
