Onyx Period Swim 3 Piece Set
Medium/Heavy Absorbency
Bring ultimate versatility and sleek, timeless style to the water with our Onyx 2 Piece Swim Set! Designed for active teens and tweens who want effortless confidence, this all-black essential delivers high-performance protection paired with mix-and-match freedom. Featuring a short-sleeve crop rashie and your choice of bottom styles, it combines low-key cool with high-tech security.
💖 Why the Onyx Set Stands Out
-
Versatile 3 Piece Design: Includes a protective short-sleeve crop top paired with flexible styling options - choose between our classic high-waisted period briefs or original period briefs with removable side ties plus BONUS free pair of regular non period swim briefs.
-
Built-In Swim Protection: Engineered specifically for the water, offering reliable, worry-free leak protection so you can swim and play without bulky disposables.
-
Secure, Active Fit: Crafted to stay put during swimming, beach volleyball, or surfing, giving teens complete peace of mind with sun protection for the shoulders.
-
Quick-Dry Performance: Made with lightweight, fast-drying swimwear fabric that feels sleek and comfortable both in and out of the water.
🏊♀️ Perfect For:
• Beach & pool days
• Med to Heavy flow protection
• Surfing or Beach Volley Ball
🌸 What's in the Set:
• Your choice of either our original swim briefs with removable side ties OR our high-waisted swim brief with StopLeak technology
• Black crop short sleeve, high round neck and covered back rashie top offering sun protection.
Please note: Knicked only manufactures the period swim bottoms, we purchase the additional pieces separately, therefore sizing may be variable. Before submitting an exchange form please ensure the actual period swim briefs have been tried on for sizing.
🌿 Designed for Summer Fun
Created by a mum, designed for real periods.
Because Knicked Swimwear allows girls to NEVER miss out on the fun when it comes to the water.
Knicked period undies have always been and will continue to be FREE FROM NASTIES such as PUL'S (plastics) or PFAS (chemicals).
Our teen model is wearing our period swim briefs in size 12/14 and wears a ladies 8 in clothing.
