I just purchased a Body Glove drysuit, and it fits like the other familiar suits. I am about 5'10, 175 lbs and the large fits fin. I went with the MED undergarment as the large was way too long for me. I trimmed the seal s tonight, but won't get to dive with it for another week. I'll test it out in the pool in the next couple of days. The suit looks nice and fits great. I can't wait to give it the real test.
