The Dual-Tone Eco Track Short brings the performance of the Solid Eco Track Pants into a shorter cut, with a contrasting colorblock panel that makes the design as intentional as the function. Modal fabric, 2x1 rib piping, and a pear-shaped waistband. For the solid version, see the Solid Eco Track Shorts. For the full shorts range, browse our men's yoga shorts collection.
Modal Fabric delivers three things that conventional athletic short fabric often sacrifices:
Shape retention under repeated use. Eco-track shorts hold their structure through hundreds of washes and intense sessions without the seat bagging or the leg opening losing its form. This is the most common failure point in cheaper athletic shorts and the specific problem recycled performance fibres address.
Moisture management without synthetic coatings. Standard synthetic shorts use chemical coatings to achieve moisture-wicking. Modal fabric achieves the same result through fibre construction, not surface treatment. This means the performance does not wash out over time the way coated fabrics do.
Sustainable by construction, not by claim. Every Dual-Tone Eco Track Short is made from Modal fibres and handcrafted in Los Angeles: no greenwashing, no offshore offsets, no sustainable branding applied to a conventionally made product.
The contrasting rib piping panel on the outer leg and at the waistband does two things simultaneously: it adds the stability and flexibility of a rib construction at the points where the short needs it most during movement, and it creates a design-forward, contemporary aesthetic that distinguishes this short from a plain athletic short. The two-tone colorway combinations are manufactured year-round. For a single-colour version with the same eco-track construction, the Solid Eco Track Shorts are the companion piece. Pair with a racer-back tank or Hybrid V-Neck Tee for a complete sustainable studio outfit.

The Solid Transition Short uses Modal rib-knit fabric for maximum softness and perfect drape: best for studio yoga and casual wear. The Dual-Tone Eco Track Short uses Modal fabric with rib piping for structure and shape retention: better for higher-intensity training, running, and outdoor activities where durability under load matters more than softness.
Genuinely. Modal fabric is made from Beechwood chips, not virgin synthetic material. The shorts are handcrafted in Downtown Los Angeles with no offshore manufacturing. There is no greenwashing here: the sustainability is in the fibre, the manufacturing location, and the absence of chemical surface coatings. For the full brand story, visit our about us page.
Yes. The Modal fabric and structured rib piping make these one of the strongest multi-use shorts in the collection: yoga, gym training, running, and outdoor activities. Reviewers specifically describe using them across multiple athletic contexts in the same week.
The 2x1 rib piping provides structural stability along the outer leg seam and flexibility at the points where the short is most stressed during dynamic movement. It keeps the short's silhouette clean during activity and prevents the fabric from collapsing or twisting at the outer thigh during lateral and wide-legged movements.
Wash cold, gentle cycle, hang dry. Unlike surface-coated synthetic shorts where washing gradually degrades the moisture-wicking performance, Modal fabric achieves its performance through fibre construction, so the performance is maintained through repeated washing without special care requirements.
Own two pairs of these plus a bunch of 4-rth's other pants. They're great. Fit well, look good (imo), great for yoga and working out. Haven't found anything like them anywhere else so I keep coming back.
These pants are a pleasure to wear for lots of reasons:
- good looking
-sexy feel and look
-great color combo
-body enhancing
-stretches where it counts

Love these hot yoga shorts, comfortable and allow me to practice and teach yoga with no restrictions.
These are great shorts for practicing hot yoga. They fit comfortable and you can move effectively through poses. We hope to start selling them at our studio soon.
I have been a 4-try customer for nearly a decade and their products and services continue to impress. The fabric is light, breathable, and soft. Excellent for yoga or lounging. But beyond that, the service is unmatched from answering multiple questions to tailoring the inseam for a guy that’s 5’7”. 4-trh is incredible.
I got these guys for hot yoga so I wanted a short inseam and fairly snug fit but not too snug…These are perfect and the material is excellent. Don’t want to wear any other shorts to class now.
These have been my go to yoga shorts for a while now. Theyre durable, having held well through so manu washes, and they fit really well. I love them so much, I ordered two more. Please never stop making them!
Great color yellow. Just a bright tank top a real head turner
Just about the nicest shorts I've ever owned. Shape, cut, styling, all very cute... not to mention how hard it is to find menswear in the Purple color range. Lovely dark shade of plum, quite soft, comfortable, and stretchy. Also, sizing advice is spot on. Very happy with these shorts.
I have three pairs of these pants and love them. I can move very freely. I also love the fabric being Polyester free and the length is very helpful for providing traction during arm balances.
These are my favorite hot yoga shorts. Super comfortable and allow for great movement.
Finally located my go-to lounge pants. Quality construction, slim profile, characterful touches like the cuff design, ideal fabric weight, stretchy waist, and the major one: the *IDEAL* length to attractively accommodate my 5' 6" frame sans excess fabric... because a dude wants to show some leg, y'know? Love these things. I own them in two colors - cinnabar red & the lovely light cloudy grey, which I prefer to the more common dark charcoal greys. To nitpick, the zippers could be higher quality and not boring black, such as a more substantial YKK with perhaps an aged nickel patina. That is the single attribute that I could envision to be upgraded in a future iteration. Still, I am so pleased with these as everyday lounge/walking pants than I cannot bother reducing a star.
I just ordered 3 more of these after my first 3 I ordered finally had to be discarded after about 4 years of constant use. Best shorts ever and only shorts I buy and wear!
Amazingly comfortable and fantastic customer service
These are comfortable and cool all rolled into one. Great for kicking it back at home or any casual event. Yoga. Running. There is no limit.
Absolutely love the fit and feel.
These are hands down the most comfortable and attractive shorts I’ve ever owned. I’ve never gotten as many compliments about an article of clothing before (all from women, fwiw). I have these in three different colors but these seem to get the most positive feedback. I’ve worn them to the beach (even swam in them), to the grocery store, to Pilates. Had to get up my nerve to go all white in public (with no underwear) but it was totally rewarding. They’re the best.
