If I am 5'10" with a 31" waist, would an XL fit me?
DAVID H
No, buy a medium I am a waste size 32

According to your waist size only you would be considered a Medium. I would recommend you contact the manufacturer and give them your exact waist and leg measurements, so that they can recommend the precise size for you.

That would be on the small side even for a medium size. My waist is a little smaller and the medium is cinched down almost all the way.

I am 6' currently a 32" waist and was probably like 34-36" when I purchased it. I think you'll be good
