The price spread
Sporti’s Poly Pro brief runs about $22, the lowest on this list, in 100% polyester. Dolfin’s Chloroban brief runs about $26. Arena’s Monogram brief runs about $32, built from recycled polyester. Adidas’s Solid Splice Infinitex brief runs about $42. Speedo’s Endurance brief and TYR’s Durafast Elite brief both sit at the top, around $45.
Fabric is consistent across the range
Every brief on this list uses a named chlorine-resistant line: HydroLast (Sporti), Chloroban (Dolfin), a recycled-polyester build (Arena), Infinitex (adidas), Endurance+ (Speedo), and Durafast Elite (TYR). The price gap here comes down to brand and construction, not a difference in how well the fabric holds up to chlorine.
Brief sizing runs by waist
Like jammers, brief sizing is based on waist measurement rather than chest, and the fit runs snug by design. Cross-check the brand’s own chart before ordering, since a size 30 shifts by a few centimeters between brands.

FAQ
Is a $22 brief a downgrade from a $45 one?
Not on fabric durability. Sporti’s HydroLast and TYR’s Durafast Elite are both built for repeat chlorine exposure, just at different price points.
Brief or jammer: which should I start with?
A jammer offers more coverage and is the more common starting point. A brief is the natural next step once you’re comfortable and want to cut drag further.
