Concerning fit. Wife got a Bern Watts in medium, and it fit me great with adjustment open. I tested a Bern Macon in Medium and it fit right. So after ordering this Allston in Medium, it was a little too tight. Returned for a Large, and with 30% on the adjuster, it fits great. This may work out as a p

Helmet does not include a non visor band. Must be an add on option. I got a chance to test fit a MIPs version of this Allston, and it runs even smaller. The weight of the helmet is also lighter than the Watts, since I realize not that it is totally different design. The Watts is a hard outer shell with separate padding, like a motorcycle helmet. The Allston is like a traditional bike helmet. Single piece molded. Both are very hard surface, with no flex. They both feel well made.
