Switched out the black for Goldenrod on my Midnight Blue Half-Jacket frames. Looks phenomenal. Like many of the socks, hard to get on and off, but well worth it. Inexpensive modification.
I'd have to disagree with jumpman about the earsocks going on very easily. I had an extremely hard time putting them on. I eventually used soap to make them slide on easier, which helped quite a bit. Once they are on though, very nice. It's also nice that they include two different nosepiece sizes with this like with the Flak Jackets. Only other complaint would be that there aren't many colors to choose from. They only sell white, rootbeer, and black right now, whereas if you order a custom half jacket you can also get red, goldenrod, and blue.
Pretty nice to custom your own frames. Earsocks come on and off fairly easy.
