Anyone use a Smartshirt?

I have just started looking into Smart Shirt, undershirts etc to watch sleep, heart rate, V02 Im not sure what the benefits would be over a smart watch or a WHOOP but it’s interesting. Im not a big watch person, so maybe a undershirt would be beneficial. (I already know my sleep is compromised, thanks to 3yr old twins)

Anyone ever used one, perhaps @Nate_Pearson and the TR crew has?

No, but I’m waiting for them to come out with smart underwear, which may help with, umm… other things.

I’ve never used one.
