Cooling vests

Does anyone USE a cooling vest?

Heat really affects me badly, I have tried some of the tips I have heard about but I want to find out about the cooling vests I see advertised. They are a little pricey to get on the off chance it might work…

Any feed back about them would be great…

My friend uses one, Her vest is a Kool max vest from Jackson technical solutions - they have a shop on amazon. It’s a cheaper one, get a bit of condensation but she likes it, does the job
