Amazon EssentialsCargo Sweatpants for Men - Fleece Jogger

Is this suitable for summer or hot weather ?

Do they shrink when washed, I ordered my normal size and they're ginormous.

Please list which size is what waist and length. The size guide is useless when it doesn't show what sizes match 32w32l?

What size should i buy if i wear waist size 40 and inseam 32?
