Finally got my order in, a eucalyptus Sheath and a moonstone Paragon, both for the base 17. Fit is great; snug all around. The Sheath and Paragon are essentially the same thickness, I was hoping the Sheath would be slimmer, but I’m coming from an old 12 Sheath without MagSafe, so it does make sense that it is thicker now. Slight rattle with the Sheath buttons, no rattle on the Paragon.
