I bought a NMG Premium Solid Shell Green suit ($69) about 2 months ago. When I ordered, I contemplated size as well. I am 6 feet tall and weigh about 240. I normally wear a XL t-shirt and waist is 38-40. I chose the XL and it fits fine. The jacket is large enough to fit additional clothes under it if I am hunting in colder weather and the pants are just fine in the waist and seat with plenty of room in the legs. I love the side zippers on the legs (easy on with boots) and the jacket has 2 pockets for additional storage. I ordered after the season so I'll put it through it's paces next spring but the quality isn't lacking from what I can tell. Stitching, material and zippers seem to be excellent quality. I did splurge and bought the 3D Full Cover Leafy Green Hat for my head as well. Complete concealment hopefully.
