As some of you know, I make a habit of soliciting reviews from the internet before buying new sparring gear. My birthday is coming up, and I'm planning on asking my parents for new head and footgear to replace my battered old century stuff. At the moment, I'm looking at this headgear and these shinguards. Both are designed not to get pulled off when doing MMA. I'm not sure if it makes a big difference, or if it's just a gimmick. Has anyone worked with either of these products before? If so, do you have any good advice regarding them? I'm also a bit worried about the sizing on the shinguards. I way about 145, and am quite skinny, which puts me on the border between "regular" and "large." This is another place where I'd love some feedback regarding how the shinguards fit.
