B-manwrote a review of Kask Rex Helmet on November 28, 2017
Familiarity: I've used it several times
Fit: True to size
I've tried several other helmets and this one by far had the most comfortable fit! There are no noticeable pressure points, and it feels very secure around the head. It doesn't look to bulky or mushroom-y either. Ventilation seems decent, and the gopro built in worked great on a night ride! I like how the visor is sturdy and can easily be tilted up to set how you want it.
One note- the gopro cover slides in and is a bit tight; to remove push down on the front tab, then slide the covering out by pushing it towards the front of the helmet.
