Perfect
Great quality, much more comfortable than the other major brand. Nice fit and not tight in that area, great value for money too!

Great quality but fit is small so but a size or two up.
Great swim breifs, decent quality material and lovely bright color. I bought 2 sizes up for a good fit (EG: my trousers are usually 32" but I needed a 36" in these swim breifs.

Nice but...
These are nice but not as good as the previous ones we've purchased. The lining at the front is not full frontal so this is a little concerning as they are kind of see-through when wet. If you're kinda big it may not hide everything.

Fine pair of trunks
Good quality, bought for my husband as husband old pair was getting thin, and a bit risqué in public!! Fit him well and he says they are comfortable. He refuses to wear swim shorts and prefers budgie smugglers. Got him a pair of black and a pair of blue.

Posing Pants.
Made me look even more stunning, if that is possible.

Sizing inaccurate - too small for stated size
Material feel is much the same as any "speedo" style swim briefs. However the sizing is off. I'm a slim 36" waist, checking the size chart and Amazon's recommendation, I ordered size 36. Struggled to get them up over my bum! Sent back for a refund.

Great all round trunks
Why did you choose this product over others?: Arena always have great quality briefs for a reasonable price, i swim multiple times a week and would always suggest these on price, quality and durability.

Confortable pour la natation
Un maillot très confortable. J'ai pris la même grandeur et l'ajustement est parfait. J'utilise pour les séances de natation et il est toujours nickel.
