Ball issues for swimmers

[BikenSwim]

I have some Arena Women's Rule Breaker Free and Women's Rule Breaker Real suits. Most of the Amazon reviews are from men. These are flat front and wide enough for men, but tight and tiny like Arena Japan men's suits. I like the squeeze, but now I find they are more comfortable if I lift everything and point up like you suggest for the Funky Trunks. The suit is fully lined and flat so it holds everything up and out of the way of my muscular thighs, especially if I downsize to L. The patterned suit is size L, the pink one is size XL.

While I don't doubt the "stitched front pouch" of the trunks works as intended I think the reason it hasn't gained wider popularity is because of limited demand.
A proper fitting (meaning snug) brief should provide enough support for active swimming.
That has certainly been my experience over the years. I have found a brief with 5cm or less sides makes a nice v shape providing support for my package.
Most guys who want support just go and wear a brief.
While I don't doubt younger boys with there "speedo issues" would go for it that may be the extent of the market.
Their website certainly gives the impression that the intended market is boys who are involved in water sports.
Good luck to them and I hope the idea works anything that gets boys to try tighter swimwear is fine by me
