Solid Eco Track Pants, a 10-Year Customer Favourite Made in Los Angeles

The Solid Eco Track Pant has been in the 4-rth collection for over a decade: a lightweight Modal track pant with 2x1 rib paneling, a flex waistband, and a silhouette that moves from the yoga mat to a run to the couch. For the full track pant range, explore our men's yoga pants. For a more structured fit, compare with our Ultra Flex Pants. 

What Eco-Track Means

Eco-track is not a marketing label. It refers to the sustainable Modal fabric used in the construction: engineered for shape retention, moisture management, and durability under repeated use. The same material principles that make sustainable yoga clothing better for the environment also make it structurally superior: Modal fibers hold their shape and resist pilling longer than synthetic alternatives.

The rib piping construction on the Solid Eco Track Pant is the functional detail that separates it from a standard sweatpant. The 2x1 rib panels running along the outer & inner leg and above the seat provide a tailored, bespoke look. While also providing stability during dynamic movement and flexibility through deep hip openers, without adding bulk or stiffness to the overall silhouette.

For a dual-tone version with contrasting rib piping, explore the Dual-Tone Eco Track Pants. For a shorter eco-track option, see the Solid Eco Track Shorts.

Built for Every Climate, Every Activity

One of the most consistent things customers say about the Eco Track Pant: it is comfortable in every climate. The Modal fabric is naturally temperature-regulating: breathable enough for warm-weather outdoor use and warm enough for cool studio environments. Pair with a racer-back tank for warm conditions or a Hybrid V-Neck Tee for cooler days. Return to the men's collection hub for the full range.

What is eco-track fabric and why does it matter?

Eco-track is made from sustainable  Modal fabric. It performs like a technical athletic fabric in terms of shape retention and moisture management, but with a significantly lower environmental footprint than virgin synthetic alternatives. Every Solid Eco Track Pant is handcrafted in LA. Try these for the softest, most luxurious fit & feel.

Are the Eco Track Pants suitable as everyday sweatpants or just for sport?

Both, and that is the point. The bespoke track silhouette, flex waistband, and Modal softness make these work as premium everyday sweatpants as much as performance yoga and training pants. Customers describe wearing them all day across multiple activities without changing. Think of them as the elevated, sustainable alternative to a conventional sweatpant.

What is the rib piping on the Eco Track Pant for?

The 2x1 rib piping along the outer & inner leg and rear panel serves two functions: structure and flexibility. It stabilises the fabric during dynamic movement so the pant holds its shape through squats, lunges, and yoga poses, while the rib's natural stretch provides give in the directions that matter most. It is the detail that distinguishes a 4-rth track pant from a standard sweatpant construction.

How do the Eco Track Pants compare to the Cuffed Yoga Pants?

he Cuffed Yoga Pants are more tailored and structured: a form-fit Modal pant with a ribbed knee cuff, better for studio yoga and smart-casual wear. The Eco Track Pant is more relaxed and versatile: a wider-leg silhouette better suited to training, running, and everyday wear. Both use Modal fabric. The choice comes down to fit preference and primary use.

Do the Eco Track Pants come in other versions?

Yes. The Dual-Tone Eco Track Pants add color contrasting rib piping for a more colorful aesthetic. The Ultra Flex Pants build on the same base construction with an additional inner-leg piping panel for even greater flexibility in extreme movement. All three are handcrafted in Los Angeles.
