Chlorine-Resistant Swimwear KnitSwim
The pool quality. Built for repeated chlorinated exposure with colour and stretch retention stated.
Chlorinated water attacks the elastic component first. A swim knit that photographs perfectly on delivery will go slack, chalky and see-through after a season of twice-weekly training if the yarn system is wrong. That is why swim is the one category where the specification has to name the chemistry, not only the weight.
Chlorine-resistant qualities use a yarn and finishing route that resists the degradation that standard spandex suffers in chlorinated water — the same reason pool training suits and resort suits are not the same fabric. We state which of the two a quality is intended for, because a resort suit sold into a swim school fails in the first month.
Swim fabric is worn at 4-way stretch in wet conditions, which is the worst case for opacity. Light colours need a denser knit or a lining. We test light colours stretched in water and can supply lining recommendations rather than leaving you to find out on a wet model.
Chlorine and salt both attack colour, not only stretch. Ask for colourfastness results against chlorinated water and perspiration rather than a generic wash test — the wash test will pass on a fabric that fades in a pool.

4 qualities for swim
The pool quality. Built for repeated chlorinated exposure with colour and stretch retention stated.
Dense 85/15 for compression one-pieces and racing-training silhouettes.
For side panels and back details that need airflow without transparency.
Soft, light and smooth for resort ranges where hand-feel outranks chlorine exposure.
Before you commit
The yarn system and finish, not the weight. Standard elastane degrades in chlorinated water; a chlorine-resistant knit is built and finished to resist that degradation. If a mill cannot tell you which of the two a quality is, it is the standard one.
Polyester generally holds colour and chlorine resistance more predictably at a lower cost. Nylon gives a softer, more premium hand and better drape — most resort ranges choose nylon, most training programmes choose polyester.
Yes. We can quote a matching lining with the shell so opacity is solved at development rather than after the first fitting.
Tell us whether the suit is for pool training, competition training or resort — the fabric route changes completely, and choosing the wrong one shows up in month two.
