I've just installed a 2.2" Hardskin Tubeless version. It weighed 806 grams and measured 52.3mm (casing & tread) on a Notubes ZTR355 rim. It aired up with a track pump and no sealant without issue. I also have a 2.2" Tubeless Light version that weighed 700 grams. I'm in Australia so can't help you on USA availability.
I've done one ride, 90km, on it as a rear tyre. I expected it to grip well but was somewhat surprised by its speed. Very fast in a straight line for having such nob height (I'm used to dry tyres like Racing Ralphs). Singletrack terrain was loose, damp soil with wet roots. It bit really well into the corners and held onto wet roots very well. I wouldn't choose it for sticky mud though as I don't think it would clear very well. I'd describe it as a Nobby Nic with a little extra cornering grip.
