Charles River ApparelMen's Raincoat

Is the inside lined with a light fabric?...or is it just nylon material throughout?

Is this long enough to cover the knee when seated? I am about 6 foot.

is this jacket warm? my son is in a wheelchair and i wanted to use this as a jacket as well as a windbreaker

I'm 6ft 4in (1.93m) tall. Would this pocho be adequate (it doesn't need to fit over a pack)?
