Immune is overstating it, strongly resistant is more accurate. I hate labeled clothing, or team clothing. It irritates me when my car has a dealer label, and do not blow smoke about how cool I will look, with whatever or wearing whatever. If my vehicle moves from A to B, is reliable, safe, and doesn’t cost an unreasonable amount to operate, I am good. Does anyone else parse ads, to see their actual claims in neutral language? And filter out the puffery filler words?
Make it noise-cancelling, however, and I am very interested. NRR 33+ brings a smile to my face.
