So my M4's and Molicares arrived. I got size medium and I think I should have opted for a smaller size. I'm about 140lbs with a 30 inch waist. I'm not super happy about how big they are on me.
They have a ton of padding which is cool, but like I said, the fit isn't that great. I tried sleeping in one last night, but the plastic backing was super hot and sticking to my skin, and the padding was too much. Wasn't comfortable at all.
Overall, I think I'm going to stick with my Goodnites until I can get some smaller sizes on order.
