I have a Polaroid Sunglasses Model name - Incognito in Blue tinted glass.
It was very comfortable in the recent Hot Summer riding but didn't test it at night as it is coloured glasses and I didn't want to stop in between to take it off if it doesn't work.
FastTrack Marketing has clearly captured the market and RayBan is very passe especially after Bosch & Lombe sold it off to an Italian firm.
If you can get an Original Polaroid Brand sunglasses do try that before buying a FastTrack - I bought mine at Mumbai's oldest department store - Akbarally's - Fort.
I think Sat or Sun I will try night riding with my Polaroid at Ghodbunder road or till Bhiwandi Bypass.
