Buying Guide
- Intended activity: For triathlons, prioritize high-impact support for running and cycling, moisture-wicking fabrics for all-day comfort, and quick-dry properties for the swim portion.

- Fabric and moisture management: Fabrics described as “Naked Feeling,” four-way stretch, or moisture-wicking Lycra help keep skin dry and comfortable across transitions.
- Protection and coverage: UPF protection is valuable for outdoor events; full coverage reduces bounce during long courses.
- Care and durability: Consider bras with color and shape retention after washing; check for reinforced seams to minimize wear over time.
- Versatility: Some options provide removable padding or multiple strap configurations to adapt from swim to run to bike without changing bras.
