- Is the Speedo PowerFlex Eco Solar brief worth it at $15.00?
- At $15.00 from Poshmark as of November 4, 2026, it is a cheap way to try a Speedo training brief. That specific suit is new with tags but has a small hole on the rear, so factor in a repair or accept the flaw.
- How does it compare with the standard Endurance+ brief?
- PowerFlex Eco is a stretchy, lightweight fabric with UPF 50+; Endurance+ is heavier and generally more chlorine-resistant. The Eco Solar is the lighter, more flexible option for training.
- What sizes does it come in?
- It is sold in men's waist sizes, and the listing shown is size 28. The fit is described as fitted with a mid rise, so pick your usual Speedo brief size.
- Can I machine wash it?
- No. Speedo specifies hand wash only for this suit. Rinse in cool water after each swim and dry flat away from direct sun.
- Does it have sun protection?
- Yes, the fabric is rated UPF 50+, which helps for outdoor pools and open-water swims.
- When is it cheapest?
