The Sidestroke stands out against traditional sport-store swimwear by utilizing high-percentage compression fabric that retains its shape much longer than standard Lycra.

Summersalt utilizes 78% recycled polyamide in the construction of The Sidestroke, turning post-consumer waste like fishing nets and fabric scraps into high-quality textiles. The brand maintains a B Corp certification, ensuring rigorous standards for social and environmental performance, transparency, and accountability across their entire global supply chain.
If you are between sizes or have a long torso, we recommend sizing up to ensure the one-shoulder strap doesn't pull uncomfortably during extended wear.
The Sidestroke is worth the investment because its durable, recycled compression fabric outlasts cheaper alternatives by several seasons. It maintains its shape and color even after frequent exposure to chlorine.
Yes, The Sidestroke provides excellent bust support through high-tension compression rather than uncomfortable underwires. Many reviewers with larger chests praise its ability to keep everything secure during movement.
Compared to mass-market fashion swimwear, Summersalt offers significantly higher material density and better UV protection. While fast-fashion suits often become translucent when wet, this suit remains fully opaque.
