4-rth Sustain Tank (Berry)

The 4-rth Sustain Tank represents a foundational pillar of the 4-rth design ethos, blending understated luxury with a sophisticated, minimalist silhouette. Designed for those who demand excellence in their daily rotation, this tank offers a refined aesthetic that bridges the gap between active performance and effortless resort-ready style.

Crafted from custom ProModal fabric, this piece prioritizes sensory experience and longevity. The textile is engineered to be exceptionally soft against the skin while maintaining superior durability and colorfast properties compared to standard cotton. This high-performance weave ensures a consistent drape that adapts to the body’s natural lines, offering a premium feel that endures wash after wash.

The structural integrity of the Sustain Tank is defined by its seamless side design, which removes unnecessary friction and promotes an unobstructed, fluid range of motion. Precision is further emphasized by the center-back seam, accented with subtle bamboo green threading—a hallmark of the brand's attention to intentional detail. The rib-knit construction allows for a tailored, form-fitting silhouette that supports anatomical contours without compromising comfort.

A versatile addition to any curated wardrobe, this tank transitions seamlessly from yoga sessions to elevated evening leisure. To preserve its sleek shape and texture, follow standard care guidelines. Explore the full range of artisanal apparel in our 4-rth Collection and find your perfect fit.
