The Tardiz has some really innovative features that make life much easier in a race. The magnetic buckle is brilliant - easier than fumbling with an old-style clip. The Aqua Vent is good too. It’s a window in the top that allows you to squirt water over your head.
The RollSys retention system works well, especially as the dial is embedded into the top of the helmet so you can make adjustments as you ride. However it still sat relatively high and wide on our testers’ heads.
