I swim 5 miles a week and have just bought my 2nd pair in a different color b/c I love them so much and the quality is great. My TYR jammers now stay in the drawer. **Q: Does anyone have any updates on how long these last in chlorine?** A: I've been wearing for about 5-months, 2x week, 2,000yds/day, without noticeable discoloration, or deterioration of the material. Legs have loosened up a bit, but they feel like they will last quite a while. **Q: These are fina approved?** A: I dont see My Kilometer as a swimsuit manufacturer listed on FINA website for approved suits for men and female. You would have to contact seller i guess to confirm but these are great quality jammers for the price. ## Customer Reviews ### ⭐⭐⭐⭐⭐ High quality *by on Reviewed in the United States 27 November 2019* I’ve swam a ton of laps in these.
