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

The 4-rth Eco-Track & Yoga Sweat Pant redefines the standard for modern loungewear. By marrying a sharp, tapered silhouette with the fluidity of performance-ready construction, these pants serve as a vanguard piece in any curated wardrobe. Designed to transcend the ordinary, they provide an elevated aesthetic that seamlessly bridges the gap between active training and refined leisure.

Expertly crafted from a high-performance Modal fiber derived from birch-tree cellulose, the textile offers an exceptionally soft hand-feel that remains breathable in any climate. This lightweight fabric architecture ensures a sophisticated drape while providing the resiliency required for daily wear, maintaining its structural integrity without sacrificing the tactile pleasure of premium organic materials.

Engineering meets anatomy in the precision cut of these trousers. The internal piping architecture—extending through the crotch and along the inner leg—is masterfully placed to facilitate superior flexibility and unrestricted range of motion. The flex-waistband, secured with a tubular drawcord, offers a stable, custom fit, while the 2x1 rib-knit side panels provide both structural support and anatomical articulation. The tapered legs create a clean, linear silhouette that is as flattering as it is functional.

A foundational element for the intentional dresser, these pants are built to retain their shape through rigorous activity and frequent use. Pair these with other essentials from the 4-rth Collection to complete your minimalist ensemble. Explore the precise fit options to select your ideal drape and ensure long-term wardrobe satisfaction.
