LXT Heated base layer NZ

Looking at potentially getting a heated baser, and wanted to know peoples thoughts.

How comfortable are they, I image the battery would get annoying, especially a 5amp?

How warm are they, and is it even ish heat?

Is there an LXT and CXT versions, or can it take both? Can’t seem to get a clear answer.

And for the kiwis, where are you buying them? Can’t seem to find any for sale or in stock.

Cheers
