It's been that way since at lease 2009 so strap in for a hot winter 😎

I use plastic fermenters which are have much worse heat conduction than glass but I'll give my two cents. I use a rectangle (about 6"x4") of pink foam insulation with a little slot chiseled out to about half the length that fits the temp probe. I just tape this tightly to the side of the fermenter and slot the temp probe into it (I use the same ITC-308 temp controller). However, what I did to test the efficacy was measure the temperature each time I took a sample for gravity readings. Since I found that the temp was within a couple tenths of a degree of the reading, I found that this was fine. Whichever way you choose to measure it, I recommend testing the internal temp that way until you dial it in.
Edit: The ITC-308 works great btw, I use it on my fermentation chamber (converted chest freezer) and keezer and have never had a problem whenever I've measured the direct temp vs the reading of the probe.
Edit 2: Also forgot to say but I use this $22 heating belt taped to my fermenter (or two fermenters which I've done twice and had equal success with). I ferment in a chest freezer so it has cooling capability but as long as your ambient temp is less than your fermentation temp you're fine using a heat source to regulate. The other thing I did when I wanted to keep the temp higher (85-95 F) for Kveik yeast and kettle sours is I wrapped the fermenter and heating belt setup with this reflectix insulation with a 1" air gap and cut to the proper size which worked perfectly (did the same thing for my full volume biab mash tun and kettle).
I made an insulation sleeve for my back bladder out of that silvery bubble wrap stuff. I got mine free with a grocery delivery, but you can get it at certain stores and here on Amazon For smaller bottles, just cut it down to size and use heavy duty packing tape to stick it together. Don't know if your bottles will still fit in your vest with that around it though.
What also helps is freezing the entire bottle the night before. I have some insulated Nathan handhelds and if I freeze them beforehand they stay pretty cool for a couple hours.
I bought reflective insulation (like this) at homedepot and taped two 25 foot long pieces together. Between runs I just wrap the whole car like so. It's extremely effective as it recycles heat from the brakes and engine into warming up the tires. Too late now, but may have been able to buy some tonight.
