AndoverVelowrote a review of MET Manta Helmet on July 26, 2019
Familiarity: I've used it several times
I picked up this helmet to try and buy a bit of speed. It hasn't worked out all that well. It fits true to size but doesn't hug the head as well as some other brands. I have also found it to be rather noisy, and if it happens to be a hot day . . . I thought I was going to get heat stroke. Obviously, I get it that aero helmets don't cool as well as traditional helmets, but this is the hottest one I've worn. I put it away until the winter.
