The KOLL cs is the only helmet on the market offering you cycling and gliding sports certification.
Indeed, we have overcome all those tests. The KOLL cs is certified for the CPSC safety standard for bicycle helmets for people 5 years of age and older as well as the American Society of Testing Materials ASTM F2040 recreational snow sports safety standard and now, adding CE EN 1078 applies for bike helmets which confirms its great design.
The new KOLL cs has a fully removable google retainer that holds the wide strap of the ski goggles in place. All you need to do is remove the retractable lens and put on your ski goggle which will completely cover your face. The KOLL cs from Blivet Sports is one of the most complete helmet on the market.
Lightweight, robust construction, made of quality materials and unique design, the KOLL cs is specifically designed for winter use. It is a helmet without openings to keep your head warm and has a retractable (and replaceable) lens to protect the face. Very comfortable, designed with an excellent micro adjustable stabilization system, it also features a three-position neck adjustment system for greater comfort and stability.
The KOLL cs is available in two sizes. S/M covering 54 to 60cm and the new L/XL 58 to 62cm both allowing you to wear one of our thin NASAK beanie.
The KOLL cs will be offered with three lenses.
