I dont know about Nitrile gloves because I currently carry latex, but I know that you can fit a pair of latex gloves into a 35mm film canister. It's a tight sqeeze, but it works. I dont know how much actual room it saves you, but it works for me;) Reason I tried it was that I was putting the gloves in by just stuffing them in at the end. Problem was that they were getting caught in the zipper of my first aid kit.
