The Fusion Yoga Short is a top 3 selling product at 4-rth every year in the collection. Lighter than an athletic short, more structured than a standard yoga short. For the full shorts range, browse our men's yoga shorts collection.Â
Fusion refers to the 2x1 ribbed knit construction: a performance-fabric body with rib throughout . This adds structure and shape retention that a non-ribbed short cannot achieve. The ribbed panels also grip lightly at the waist and thigh to keep the short in place through movement without pinching or restricting.
The result is an elevated short with more silhouette & more flexibility than a structured gym short. For hot yoga practitioners who want something between a form-fitting yoga short and an athletic training short, the Fusion fills that gap precisely.
Compare across the range: Solid Transition Short for maximum softness and drape, Fusion Short for more structure and shape, Ultra Flex Short for maximum four-way stretch in high-intensity training.
The Fusion Short crosses over between yoga, gym training, running, and casual outdoor use more naturally than any other short in the collection. Reviewers describe wearing it across all four contexts in the same week. The RIB construction gives it enough structure to look intentional outside the studio and enough stretch to function across all athletic activities.
Pair with a racer-back tank for hot yoga, a Hybrid V-Neck Tee for the gym, or wear alone for outdoor training. Available in a range of colorways.

The Fusion Short uses a RIB knit with ribbing at the waistband and leg opening, giving it more structure and shape. The Solid Transition Short uses a french terry fabric for a softer, more draped feel in the body with side paneling of 2x1 RIB. Both are excellent for hot yoga. Choose Fusion for more form-fitting shape. Transition for maximum softness.
Yes, it has been a hot yoga studio staple since it launched. The fabric is lightweight and breathable enough for heated practice, and the ribbing at the waist and leg keep it in place through all poses without shifting.
The inseam sits at approximately 4 to 5 inches, placing it at mid-thigh on most body types. This is the most versatile length for studio yoga and general training. For a shorter inseam, see our men's short shorts.
Yes. The four-way stretch and structured RIB construction make it a strong multi-use short. Reviewers specifically mention using it for running, gym sessions, and outdoor activities alongside yoga practice.
True to size for a performance fit. Size up one if you prefer more ease through the hip or thigh. Full measurements are on each product page. Contact us via the contact page for specific fit questions.
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.

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 thatâs 5â7â. 4-trh is incredible.
I got these guys for hot yoga so I wanted a short inseam and fairly snug fit but not too snugâŚThese are perfect and the material is excellent. Donât 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 Iâve ever owned. Iâve 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. Iâve 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. Theyâre the best.
