Well... yesterday I went for a 210 km 'toot'. Temp was about 35C = 96F, and I was wearing mesh jacket, mesh pants. By the half-way point I was pretty hot, so I parked, removed my jacket and tee, then did the ABOVE procedure.... (FIRST time I'd done it wearing mesh!)
My tee was SOAKING wet when I put it on (QUITE "bracing" I might add...), tucking it into the waist of the pants, cinching my kidney-belt over top, then adding the jacket. By the time I was properly ATGATT, the "cool" was gone, and I was warm all over, the water down into the top of my underwear. Started the GREEN HORNET, snicked it into gear, started riding. Within probably 50 feet it felt like I was sitting in front of an air-conditioner, ALMOST too cool...!
I took note of the time, as it's an hour and a half home from there. The REALLY cool lasted about 45 minutes, followed by the temps gradually increasing over the last 45 minutes, but STILL cool beneath the kidney-belt and top of my shorts right up to arrival home.
I would now add that the coolness length-of-time is directly related to the amount of air-circulation through your gear (I KNOW - PRETTY obvious...!), as my jacket (when I mentioned the 2.5 hours) was a textile jacket w/ several small zippers for air-circulation, this at the end of about 28 days on the road including Alaska.
BTW - our forecast temps over the next few days will go OVER 40C = 104F!!!
