Sauna Suit for Men Hot Sweat Suit Sauna Shirt Sweat Body Shaper Workout Neoprene Suit Zipper Short Sleeve

Bought one of these before that didn't go to my waist line. I'm 6'4 230. What size would you recommend that would go to my waist line?

Is the sweat material also on the sleeves? Or just on the upper body and midsection?

Are the sleeves material also neiorene?
