Nanica Slim Rib Swim Brief

The Nanica Slim is an even more daring version of our Nanica swim brief, featuring narrower sides and a sharply cut silhouette for a bold, standout fit.

Ribbed fabric with a substantial feel and a soft, velvety touch.

Designed and Made in Brazil

Each BANNANNA swim brief is handmade in Brazil in small batches, combining artisanal craftsmanship with exclusive cuts designed to flatter the body. We use high-quality Brazilian materials. The fabric offers a subtly textured feel, providing comfort, stretch, and durability while maintaining its shape over time. The soft inner lining feels smooth and comfortable against the skin from the very first wear.

Details & Certifications

Our fabrics combine performance and comfort with thoughtful sustainability features. The dyeing process uses reclaimed water, reducing the consumption of potable water. The polyamide yarn is biodegradable and developed with Amni Soul Eco® technology, allowing it to decompose significantly faster after disposal and helping reduce environmental impact.

The fabric also features Oeko-Tex® Standard 100 certification, confirming it has been tested for harmful substances, and Stretch + Wet® technology, which maintains UPF 50+ sun protection even when the garment is wet and stretched.

Care

A short ritual keeps the fit, the color, and the fabric intact.

• Hand wash with mild soap. No machine, bleach, or fabric softener.
• Cold water, always.
• Press gently to remove water. Never wring.
• Dry flat, in the shade.
• Avoid rough surfaces. Stone, concrete, and pool edges shorten fabric life.
• Wash light tones on their own.
• Store only when fully dry.

Treated this way, the swim brief outlasts the season.
