HanesBig Men’s Tagless ComfortSoft Crew Undershirt Tall, Various Pack Size Options (3 Pack or 5 Pack)

Ok, so are these v-necks short length or long length??

I'm a size 45 chest. What size should I get -- L or XL?

Material what is the material these t shirts are made of?

When you say "advanced odor protection technology," does that mean you've poisoned the material with something that won't wash out!?
