If you have a big head forget the Gallet 250. Bought one recently my thoughts v Alpha ( my current helmet)
1. I wear a large Alpha ( head measures top end of medium long bottom end of large ) could not getter Gallet to fit so had to sell it on
2. The visor system is really difficult to work while wearing gloves ( do a lot of line work with no doors on in winter )
3. The chin strap system doesnt seem very robust
4. Shell is smaller than the Alpha, although dont have a problem of sticking head outside a 500 with no door ( i m 6 ft 1 )
5 Gallet offer a load of different options
6 Took Gallet 4 months to make one for me, not a bad price twin visor normal headset was £ 1700 here in UK this year
