I am 6'1", 230 lbs with a 36" waist, wear a suit size 42L, and usually get a size Large. I ordered the XL for extra space, but I think I could've gotten by with the L as it feels these are already cut to be roomy. I look a little undersized wearing the XL, but it may shrink after a few wears. I'll update this if it does.The material is a very dense weave and feels smooth and cool to the touch. The stitching is well done and the buttons are solid sewn on and the button holes are tight. There's elastic on the waist for comfort and there are two button locations to get the right sizing. The fly is held closed by magnets, but I find they are rather weak and the fly doesn't stay securely closed.My only issue is that these are not very warm. The first night I wore them my arm was sticking out from under the covers, and it got really cold to the point I was shivering. Room temperature was around 66 degrees. But it's fine as long as you stay under covers. And these will be great in warm summer nights as this fabric is very cooling and breathable.There are relatively deep pockets in the pants so my smartphone stays in; shallower pockets in my other PJs tend to let it slip out too easily. There's also a pocket on the shirt which is also decently sized.I would give this a full 5 stars except for the price; easily 3 to 4 times more expensive than my other PJs. I can't really say this is that many times better. And the weak magnets on the fly is a negative.
