Sizes
The sizes are off; I'm usually a large in briefs but the large was way too small for me. So I contacted LAMBS and they were very swift with sending me XXL briefs (i went up a size since I thought it would be small as well) and the XXL doesn't fit me either. The XL probably would have been a better choice but regardless, great company, great product, great purpose. They have the research and studies to back up what their products claim to do (protect people from EMF).
