Well, after a week of ATGATT, I'm Hatin' it pretty bad. It's exactly like putting a condom on the motorcycle experience. Yes, it protects - but also desensitizes. The full face helmet is claustrophobic, the thick armoured jacket and pants restrictive. No wind in your face, can't hear other vehicles as well or other audio cues. The thick suit lessens sensory input from machine and road. Frankly, as insulated from everything as I am with this setup, I feel strangely vulnerable and Less Safe.
I can here the scoffing, and the "I can't believe how stupid that guy is" and all that, but I am only reporting my own experience. I'll wear this stuf as long as it's winter, but man will I be glad when spring comes and it's back to my half lid, jeans and leather jacket.
