Review: Good suit - This is my first pair of swim briefs I've tried, and so far it's performing great. Material is comfortable and stretchy, and dries quickly. My waist is 32 inches and I followed the Speedo size guide on their site, and ordered the suit in 30. The fit is snug but the suit comes on and off easily. The look is skimpy, with the side seam measuring 1.75", and I think on a taller guy it may look too small. I appreciate the construction, because the front seam creates a little gusset room up front, so it cups around you instead of making a vacuum-sealed look in the front. Freedom of movement is great in the water, and everything stays secure. Overall, very pleased with the purchase after a half-dozen swims. Review: Solid suit - Great fit, quality material and workmanship. Should stand up to chlorine when properly rinsed after use. ## Features - LONG-LASTING: Lycra Xtra Life fabric lasts 5-10x longer than ordinary spandex by retaining original shape and resisting color fade - QUICK-DRYING: Low-moisture absorption for fast comfort right out of the water - NO PINCHING: A front gusset creates comfortable, breathable room around the crotch area - A BETTER FIT: Specialty 9 Thread Flatlock Technology molds to your body's natural shape and keeps everything in place through vigorous exercises - UV & UPF 50+ PROTECTION: UV Block the Burn technology protects against harmful UV rays and has been tested to meet 50+ UPF protection - Xtra life lycra fabric lasts 5 to 10 times longer to give you more value for your money ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08Q4WRKZF | | Best Sellers Rank | #20,002 in Clothing, Shoes & Jewelry ( See Top 100 in Clothing, Shoes & Jewelry ) #1 in Men's Athletic Swimwear Briefs | | Customer Reviews | 4.4 4.4 out of 5 stars (4,989) | | Date First Available | May 6, 2015 | | Department | mens | | Item Weight | 2.4 ounces | | Item model number | MPWRFLXSOLARBRIEF | | Manufacturer | Speedo | ## Images ![Men's Swimsuit Brief PowerFlex Eco Solar - Image 1](https://m.media-amazon.com/images/I/51E0DzSstSL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Questions & Answers **Q: Are these really stretchy?** A: Probably somewhere between stretchy and really stretchy. I could be several inches bigger in the waist and still wear the suit I own but it would be tight. So yes, the materiel is stretchy. I rinse it after each dip and it seems to fit the same each day. A well constructed suit. **Q: Size M in brief underwear. 30-31 in jeans. Muscular legs and butt. 5'5". What size do you recommend?** A: I am 5’7” with muscular legs and normal butt. I bought 3 Speedo Powerflex Eco Solar swimsuit briefs or bikinis with 1” wide sides and I bought and wear size 34 because I am big-boned and a bit muscular. I bought two red and one white swim briefs and their material seems to be more resistant to chlorine and a bit thicker. This might cause some drag. Before purchasing these swim briefs, I would go through swimsuits like water. They would wear out because I have been swimming 6 days a week since August 2020. I consider myself a swimmer wannabe. I usually swim daily between 1k to 1 mile if I have time enough. with these swimsuits I cannot be any happier. I hope this helps. **Q: My husband is a 33 in pant size what size shoulf I order him for best fit?** A: my order was for a 36 and the person it was was ordered for wears a 36 waist and it fits fine. **Q: What did I buy in swimming briefs ?** A: I purchased Speedo Solar 1 swim briefs, size 32 in red color. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good suit *by A***R on January 18, 2026* This is my first pair of swim briefs I've tried, and so far it's performing great.
