The racer-back tank is the top that disappears during practice: no collar shifting, no sleeve restriction in arm balances, no bunching in binds. Handcrafted in Downtown Los Angeles from 2x1 rib-knit Modal, form-fitting and built to move with the body. Pair with any bottom from the men's collection for a complete studio outfit.
Most men choose between a standard tee and a sleeveless vest for yoga practice. Both have functional limitations.
A standard tee bunches at the collar during forward folds, restricts at the shoulder during arm balances, and traps heat in a way that Modal fabric alone cannot fully offset. In a heated studio it becomes a practical problem within the first fifteen minutes.
A standard sleeveless vest often has wide shoulder straps that still restrict rotation during specific arm positions, particularly binds and backbends where full internal and external shoulder rotation is required.
The racer-back cut solves both: the narrow strap at the back eliminates shoulder restriction completely, the low front neckline prevents collar bunching in forward folds, and the open back dramatically increases airflow in heated practice. The 2x1 rib-knit Modal construction provides just enough structure to stay in place without the tank shifting or riding up through dynamic sequences.
For other top options, explore the Hybrid V-Neck Tees for a sleeved alternative or the full men's tanks collection for all styles.
The racer-back tank is the most versatile top for warm-weather and heated practice. Pair with Solid Transition Yoga Shorts for the go-to hot yoga combination in the 4-rth range. Pair with men's short shorts for Bikram. Pair with cuffed yoga pants for a cooler studio or a morning practice where the temperature varies. The solid Modal colorways and minimal branding mean these also work for beach days, outdoor training, and casual summer wear without looking like studio-specific clothing.

The racer-back eliminates the shoulder strap restriction that standard tanks create during arm balances, binds, and overhead poses. Full internal and external shoulder rotation is unobstructed. The narrow back strap also removes a layer of fabric that traps heat in a heated studio, making the racer-back significantly more comfortable than a standard tank in Bikram and hot yoga conditions.
Yes. The 2x1 rib-knit Modal construction provides enough structure and body-fit to stay anchored through handstands, downward dog, and fast-flowing sequences. The only seam runs down the centre back, which keeps the front panel flat and in place regardless of what the arms are doing.
2x1 rib-knit Modal: a birch-tree derived fiber shaped into a ribbed construction that is soft, form-fitting, naturally moisture-resistant, and breathable. The same premium Modal used across the 4-rth pants and shorts range, in a rib configuration that adds structure and contour to the tank silhouette.
Yes. The minimal, clean design and solid Modal colorways make it a natural choice for gym sessions, outdoor training, beach days, and casual warm-weather wear. It functions as a premium everyday tank as naturally as it functions as a yoga top.
The fit is form-fitting but not compressive: a close silhouette that follows the body without restricting it. Reviewers with athletic builds consistently find the fit through the chest and shoulders comfortable. Size up one for a more relaxed feel. Full measurements are on each product page.
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.
