Review: My go-to swimsuit - Update: Still going strong with these briefs, but I do want to state that I ended up with one size larger than what I purchased (36 from 34). To tell the truth I did not heed my own advice: I did not properly measure my waist size before buying the smaller size. The difference with sizing up is having more coverage to your hips and groin. Compared to other briefs, I find this brand and model to be the most comfortable. It's snug and soft while the lining is the least abrasive. I prefer open water swimming and would bring these every time no matter the location. You still need to apply Vaseline or something similar for longer ocean swims because of the properties of salt water. Take the size chart seriously. Measure your waist and buy accordingly. It will feel tight but as the directions state, go into the water a couple times and it will stretch out to the appropriate fit. Side note: I bought these at my local sports store several years ago. Same 78% Eco Recycled Nylon and 22% Xtra Life Spandex marketing, but it was made in Vietnam instead of Sri Lanka. No discernable differences.
Review: Keep in mind this is a race suit, despite the title - Speedo has always made a good product. The sizing chart, however, is for race suits, which are much tighter than a workout suit. I normally wear a 32 pant which means a 30 suit size. But this was far too tight on me for workouts. Again, would be great for a race suit you wear for just a few minutes, but not hours for a workout.

### ⭐⭐⭐⭐⭐ My go-to swimsuit

Speedo has always made a good product. The sizing chart, however, is for race suits, which are much tighter than a workout suit. I normally wear a 32 pant which means a 30 suit size. But this was far too tight on me for workouts. Again, would be great for a race suit you wear for just a few minutes, but not hours for a workout.

### ⭐⭐⭐⭐ A nice suit for lap swimming, but advertised size is too small and too tight in legs
*by K***R on November 26, 2025*

I have a stocky build. I've been wearing Speedos through the late 60's early 70's for racing and then later in the 70's playing water polo in university. Along the way Speedos instead of beach trunks were normal pool wear while lifeguarding. I still swim to keep my cardio up for other athletic activies and maintain mobility, and I'm still picky about swim suits intended to be primarily worn in the water swimming laps. I can't quite find a suit withthe fit of those suits back in the day any longer, but the cut of this suit will do. It is a bit more skin tight/compression than I prefer, but it will work for me at least. While it doesn't say it in the description (it should) this Speedo has a 3" wide side panel. I am normally a 36"/37" belt size in casual pants. I had to upsize to size 40 for this suit to fit comfortably, and it is still a bit too tight in the legs. I don't think you would need to have a stocky build to need to upsize above your normal pants size. If you have above average quads and glutes, whatever your build or belt size, you may also need to go up a size to avoid finding the legs are too tight. If how your pool suit looks when out of the water is important to you, this emerald blue is nice. I have no idea whether or not it is flattering from a fashion standpoint - I assume the primary purpose of buying a suit like this is to be in the pool swimming, not lounging on the deck. So far, next time I might look for something from Tyr or Arena, but I wouldn't mind buying this model of Speedo again. The reason I docked it one star is I don't think the sizing is true for North American men and it is just a little bit too tight through the legs and the body of the suit.
