4-rth Eco-Track & Yoga Sweat Pant (Charcoal w/Grey)

The 4-rth Eco-Track Yoga Sweat Pant represents a masterclass in modern athletic design. By merging the technical requirements of high-performance movement with a refined, architectural silhouette, 4-rth has created a definitive garment that transitions seamlessly from active practice to elevated leisure.

Crafted from premium Modal fiber derived from sustainable birch-tree wood pulp, this textile offers an unparalleled tactile experience. The fabric is engineered for a lightweight, breathable drape that maintains its integrity through extended wear, providing a cooling sensation that feels weightless against the skin while resisting the rigidity of traditional cotton-based sweats.

The structural engineering of these trousers prioritizes anatomical precision. Tapered legs cultivate a sleek, vertical geometry, while integrated 2x1 rib piping—running through the crotch and along the inner leg—functions as a sophisticated gusset to provide superior range of motion and structural stability. The waistband features a flexible construction reinforced with a tubular draw cord, ensuring the garment remains anchored during vigorous activity while offering a customized, clean-lined fit.

These pants are designed for those who curate their environment with intention. Whether utilized for yoga, high-intensity movement, or a refined work-from-home aesthetic, the Eco-Track pant maintains its form with a polished, minimalist finish.
