What it actually is
The Sony Reon Pocket Pro Plus sits in a small pocket stitched into a compatible shirt, right against the back of your neck. It uses a Peltier cooling element to pull heat away from your skin. No fan noise, no bulk, just a quiet slab of tech doing its thing. You control it through an app, or just leave it on auto and let the sensors sort it out.
Honestly, the concept sounds like something from a Japanese gadget catalogue from 2035. Which it basically is. Sony has been refining this since 2019 and the Pro Plus is the most capable version yet.
Who this is actually for
If you commute on packed trains, work in a poorly ventilated office, or simply run hot and have always wanted a personal climate bubble, this makes a lot of sense. A mate of mine used the previous Reon on a long-haul flight and said it was the only reason he slept. I believe him.
For casual home use? Probably overkill. Just open a window.
The 15-hour battery claim is decent, though real-world use on maximum cooling will eat into that. The device also only works properly with Sony's own shirts, which is a bit of a faff and an extra cost to factor in.
My honest reservation
At roughly £138 before you even buy the shirts, this is a commitment. It works, the tech is solid, and the silence compared to a neck fan is a genuine improvement. But it is niche. If heat genuinely ruins your day on a regular basis, this could change things. If you occasionally get a bit warm, it probably won't.
