I've just been reading about this superduper thermal!

So does the stretchy support keep your muscles warm thing mean that you don't need a bra?

If it doesn't you can't wear it next to your skin as it suggests!

Will it be 'man enough' to keep my boobs under contol?

I wear a tight top that is designed to go under padding used in rugby. It is comfortable and does help to moderate your temperature. My boobs are tiny so only need minimum control so I don't know how effective it would be for the more well endowed.
