Hands got a little sweaty. I wish there was more breathability to the fabric. Inside zipper arrangement is a little confusing (to me, at least).
Does exactly what it says it does. I've never had any light leaks with it. I would, however, recommend buying a bigger size. It can be a little small at times (especially if loading a bulk film loader).
I have had or used three or four changing bags in my life, this one is the best quality of all of them. Absolutely NO light leakage. Highly recommendable.
