Best athletic cups for guys?

I'm trying to convince my boyfriend to wear an athletic cup as he joins me at my krav maga classes. Do you have any recommendations for which ones work best? The main criteria I think are comfort and protection from various angles. He is being a bit reluctant because he says he thinks they sound uncomfortable, so I'm trying to find him something better than a no-name store brand that might not work well anyways. He says he'll wear it if I can find him a good one, and I'd rather keep him safe than let him get hurt without proper gear.
