LAPASAMen's Thermal Underwear Set Soft Fleece Lined Long Johns Light/Mid/Heavy Weight Base Layer Top & Bottom M11/M24/M57

Is it possible to order different size top and bottom? i need a 2xl too and xl bottom and can’t seem to order these separately. any thoughts? thanks.

Are these really heavyweight? Need them really soft and really warm for90 y o father.

Should I get light or mediumweight if I'm going to a football game in 38 degree Fahrenheit weather?

Any chance to buy xl top ,L bottom ??
