I was lucky enough to get a Cotton Carrier system to try out.. At first glance its a great system and very well made, plus its Canadian so even better lol This past weekend I was able to test it out at a track day and really test it out in a real world situation..After getting used to how to put in your camera( the twist and lift technic ) it works really well.. I love that can I hook my cameras up and not worry about them swinging around or knocking into things..Its a pretty fast system too, not as fast as the Black Rapid strap dual R Strap but pretty close. It would be hard to choose between both systems..I do like the Cotton Carrier a little more because of how stable it keeps your cameras..and having it on your chest is great. Im going to put both carriers through more test..But Im glad I have both lol.
