Terry Sweats For 200lbs 6’5ft Man

Hey guys I’m planning to buy a pair of Terry Sweatpants Relaxed Fit for my husband as a surprise gift. I have no idea how men’s sizing is. Half his clothes also don’t fit right because he’s taller. So I’m wondering if I should get the XL or L? His average pants inseam is 33in (although I don’t think it’s always perfect) and his waist is 35in
