These were a great solution for our competitive swimmer kid who never wants to miss out on practice. They are comfortable and you cannot even see them under the suit.

- Description
Swim, compete, and move with confidence — period or not.
The UnderSwim (OG Fit) is the official period-safe swim underwear of Swimming Australia. Worn invisibly under any swimwear with regular bottom coverage — one-pieces, bikinis, and race suits — it holds the equivalent of 2–3 tampons or 4 regular pads with zero added bulk. The water-resistant outer coating keeps water out while the absorbent inner layers lock flow in. Chlorine-resistant and free from PFAs and harmful chemicals. Comes packaged in a waterproof wet bag for easy post-swim storage. Rinse after every swim to keep the coating working its best.
Sizes: Youth 10-12/Women's XXS/0 - Women's XXL— see size chart for measurements. Please note that sizing is based on the Eltee Swim size chart but exact measurements are available. Please measure before purchase since all items are non-returnable.
Care: Machine wash cold, no fabric softener. Air dry only.

Care Instructions
Hand wash or machine wash on cold. You can use detergent but don't use fabric softener or bleach. Hang dry. We recommend avoiding putting leakproof swim in the dryer, as high temperatures can degrade the elastics and fabric over time.
