Eh, I'm not putting any money on that. Part 1 of Stross' "Accelerando" already ran the concept of smartclothes into the ground before smartphones were even a thing, and nobody wants a vest that's also a storage and compute cluster that sends passive-aggressive emails to your smartglasses when its simulated personality gets lonely.
Running an electric cooler creates heat, the weight of the batteries to run an electric cooler means the wearer would need to do "more work" which creates even more heat, batteries generate heat when used, solar panels soak up heat from sunlight, etc. So after a short amount of use the wearer would be generating more heat than the device could cool off. Perfect, "3~5 years away", vaporware.
My mones is on wearables by way of Lorawan or IOT. The jacket that tells you when it stops being wet or whatever.

Solar powered cooling vest.
Too useful
Very useful, but impossible.
