Patagonia Women's Nanogrip Bikini Bottom

The Patagonia Women's Nanogrip Bikini Bottom is designed for women who want their swimwear to stay put through every wave, paddle session, or lineup wait without constant adjusting. Built with a recycled nylon and spandex blend, the fabric offers four-way stretch and a smooth, chlorine- and saltwater-resistant finish that holds its shape dive after dive. The signature Nanogrip elastic along the waistband and leg openings is the standout feature, using a silicone-free grip technology that keeps the bottoms secure against the skin without the discomfort of traditional tight elastic or the slip of ungripped edges.

The fit sits at a moderate rise with a classic coverage cut through the seat and legs, striking a balance between function and everyday wearability. It's tailored for active use—surfing, swimming, paddleboarding—rather than purely lounging, so the silhouette avoids excess fabric that could shift or bunch during movement. Flatlock seams reduce chafing, and the overall construction reflects Patagonia's focus on durable, performance-driven design rather than fast-fashion swimwear that degrades after a season of sun and salt exposure.

True to the brand's environmental ethos, the bikini bottom is made with Fair Trade Certified sewing practices and uses recycled materials to lessen its environmental footprint, appealing to women who want their beach and water gear to align with sustainability values. It pairs easily with Patagonia's matching bikini tops for a coordinated look, but it's equally suited to mixing and matching across suit styles. Available in a range of solid colors and prints, the Nanogrip Bikini Bottom suits everyone from daily ocean swimmers to casual beachgoers who simply want swimwear that won't require constant tugging and readjusting.
