Great!, but a quick release helmet clasp would be nice
Really like it, this time I order a large, next time I will order a medium. A quick release clasp would be nice, the stock standard helmet clasp is a little cumbersome, The field of view is outstanding and the flip down sun visor it also awesome! But a little difficult to engage. Maybe with a little work and wd40 it will move easier. Otherwise very pleased!

Does the face shield lock in completely? Based on the pictures, it looks like there is a gap and that it does not have a complete, air-tight seal.
A shopper on Jul 10, 2017
BEST ANSWER: Yes, the face shield on the Sierra II Helmet locks into place for an air-tight seal.
