Biathlon

Casco Spirit Vautron.  This is the latest version of the flip-up visor popular with World Cup Biathletes.  Won't fog, easy flip up/down for quicker range times, and Vautron lense is light, durable, and photochromatic.  100% UV Protection.  Available in Neon Yellow (NEW FOR 2016-17!), Black, or White Frame.  Medium fits most faces.  Large for greater 'windshield area'.  The Medium and Large frames are identical, only the lense is bigger on the large.  Large tends to work better for Biathlon as it allows for greater clearance of the lense above the rear sight.  Please specify Size and Color preference.  Overall weight is only 50g/1.8 Oz!.
