fit great for traning/racing
Great training/racing brief, is tighter at the top which helps keep them on without needing to worry the whole time about the cord, but can be uncomfortable if you need to wear for a long time. Being a swim brief , the sizing fit is tight but thats what you want for training. Good value for money compared to the other brands, and the Arena quality is great.

Snug fitting brief.
Purchased as replacemnt for a pair that I bought a few years ago. These seem slightly smaller than the originals mainly I think because there is less 'stretch' in the material.

Tight fitting and bright colour
This is a tight fitting brief, I would not size down, I'm a 33in waist and a size 34 fits me snugly. The fabric is dense and not see-through even while wet as there is a liner in the front. This brief is cheaper than other brands while maintain its high quality. Only grip i have is the tag that i need to remove, its hardly a issue with a pair of scissors but something to make sure you do as the tag is visible though the fabric while wet.

A little on the small size, feels very tight in the front
I choose from the size guide provided, however I feel they are at lest two sizes smaller, I’ll keep them for now incase I change shape in the future, great colour and fabric choice, just need to rethink the sizes ..

Fantastic Arena swimbriefs. Nice fit.
I love wearing swimbriefs and I love Arena swimbriefs. These look great and feel great. Nice fit. Going on holiday in June and I'm definitely taking them with me. I already wear them in the pool at my local leisure centre.

Perfecto para el nadador diario. Tarda bastante en degradar el tejido por el efecto del cloro y agua.
