4-rth Sustain Tank (Charcoal)

The 4-rth Sustain Tank represents a definitive pillar of modern athletic apparel, merging functional geometry with an elevated sartorial sensibility. Designed in Los Angeles, this top-selling piece transcends standard activewear, serving as an essential foundation for the discerning minimalist.

Crafted from custom ProModal fabric, the textile architecture of this tank offers a sensory experience superior to traditional cotton. The weave is engineered for exceptional durability and deep, lasting colorfastness, ensuring the garment maintains its structural integrity and soft-touch feel through years of repeated wear.

The construction prioritizes an uninterrupted silhouette, deliberately omitting side seams to facilitate a fluid, non-restrictive range of motion. Each detail is deliberate, from the precision stitching to the subtle, architectural back-seam detail finished in bamboo green thread, emphasizing the tank's commitment to clean lines and anatomical comfort.

Integrating seamlessly into a curated wardrobe, this tank is designed to retain its shape and refinement regardless of the intensity of your movement. Explore more foundational pieces in our 4-rth Collection to complete your aesthetic.
