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

The 4-rth Eco-Track & Yoga Sweat Pant stands as a cornerstone of modern, high-performance tailoring. Merging the ease of classic loungewear with an elevated, contemporary silhouette, this piece defines the vanguard of comfortable, intentional style.

Crafted from lightweight, sustainable Modal fiber—derived from premium birch-tree pulp—the fabric offers a liquid-like drape and an incredibly soft, skin-responsive hand feel. This moisture-wicking textile ensures a refined, temperature-regulated environment for the wearer, maintaining its structure and rich color through seasons of consistent use.

Engineering meets movement in the pant’s meticulous construction. Featuring tapered leg geometry and full-length internal piping through the crotch and inseam, the design prioritizes structural integrity and superior flexibility. The 2x1 ribbed paneling spanning the side to the upper rear delivers anatomical stability, while the flex waistband, secured by a tubular drawcord, ensures a customized, pressure-free fit that moves in absolute harmony with the body.

Designed for the transition between active practice and metropolitan leisure, these trousers offer a versatile, sleek profile that defies traditional expectations of casual wear. Discover the complete range of curated essentials within our 4-rth Collection. Each pair is built to retain its form and finish, ensuring your investment remains a foundational element of your wardrobe for years to come.
