Rackets, I had the Nolan b4 I wrecked my Valkyrie. It took a good hit on block top and held up fairly well. Would I buy another one (NO). After 2yrs the lining was starting to fall apart. I liked the concept of the shield but in the up position it blocked the air intakes. It's NOT SNELL approved. I opted for the HJC AC3. Shield flips up, doesn't block the air intakes, has speaker pockets, has a removable liner for washing, is SNELL approved.
