Just put in a couple of long rides with the GT-Air on my bounce and it has performed well with some minor gripes.
1st day was a hot one and I felt that the front air vent wasn't flowing much air but that is in comparison with the Hornet, but overall the top vents did their job well once I remembered which position was open and the flip down visor was brilliant.
The 2nd Day was damp and drizzly and the visor seal worked very well with no water finding its way onto the inside of the visor, which happens a lot with a Hornet. As the day was overcast I left the flipdown visor up out of the way but when I came to a brighter patch I found that it had been covered in mist/damp and it didn't clear with the main visor cracked open, so suspect some damp had got in via the front top vent :/ .
Overall though very comfortable lid and its booked its spot as a longdistance foul weather choice. I may still use the Hornet for shorter/hot day rides as I like the airy feeling it give me, though if I take the bottom chin curtain out of the GT-Air it may feel more airy too.
