Sometimes less is more. The LS2 HH566A Half Helmet offers motorcycle riders less, and more. The low profile, tri-composite fiberglass half shell, with a built-in, Full Eclipse drop down sun visor offers more than you'd normally find in a value priced half shell motorcycle helmet. The sun visor drops and retracts with the simple flick of a lever. The quick release chinstrap makes it easy to get on and off, while the wide V strap helps keep it where it belongs. The liner is made of a wicking fabric to keep you cool on hot days, and resists odor and bacteria. The LS2 HH566A motorcycle helmet offers more of less, more or less. Please note: The sun visor on the "A" model is not replaceable. It is protected by the helmet shell when retracted, but it will not accept replacement shield. If you are looking for a replaceable sun shield, consider the LS2 HH566 (non A model). DOT approved.
