Quick answer
For a versatile two-piece swim set, pair the Swim Reversible Sport Top with the Swim 4.5 Shorts. The reversible top offers two looks in one, while the shorts feature a water-activated jellyfish print for a playful surprise.
Why combine these two pieces?
The Swim Reversible Sport Top and Swim 4.5 Shorts are designed to work together as a mix-and-match set. The top’s sporty silhouette and reversible color options complement the shorts’ innovative water-activated print, giving you a coordinated look that stands out at the pool or beach.
Key differences to consider
The top is reversible, offering a black side for a classic look and a rainbow side for a bolder statement. The shorts use color-changing technology that reveals a gray jellyfish pattern when wet, returning to black when dry. This means the top’s style is fixed once you choose a side, while the shorts’ pattern changes with water exposure.
Trade-offs at a glance
- Style versatility: The top is reversible (black vs. rainbow), so you can switch your look without changing clothes. The shorts’ print only appears when wet, limiting its visual impact when dry.
- Fabric and care: Both pieces use recycled materials. The top’s double-lined fabric offers support and coverage; the shorts’ color-changing fabric requires gentle care to maintain the effect. Hand wash or use a gentle cycle to preserve the water-activated print.
- Fit and activity: The top has wide straps and a sporty style, ideal for active swimming. The 4.5-inch inseam shorts offer moderate coverage, balancing mobility and modesty.
Product facts at a glance
- Swim Reversible Sport Top: The Swim Reversible Sport Top is based on the best-selling Compression Top with double-lined fabric made from recycled water bottles. You get two color options in one top, and the recycled fabric makes it an eco-friendly choice for daily swimwear.

Swim Reversible Sport Top - Swim 4.5" Shorts: The Swim 4.5 Shorts feature water-activated fabric: black when dry, revealing gray jellyfish print when wet. The print adds a fun, interactive element to your swim look, but the effect is temporary and only visible when the shorts are wet.
