There's a bajillion of them around if you search "neck cooler" or similar. Very simple product sticking a few commodity items together. Some do only have fans though.
When I looked a while ago there wasn't really a clear winner or high quality unit. There is the "Coolify" series that are much more expensive but still somewhat middling reviews overall.
