CrossFit demands a short that does not bind on a squat, sag during a toes-to-bar, or soak through on a rower sprint. The wrong pair can end a workout early—chafing, restrictive waistbands, and flimsy zippers that fail mid-metcon are real frustrations. Focused athletes need a short built to survive high-volume, multi-plane movement without demanding constant adjustment.
I’m Mohammad — the founder and writer behind ProteinJug. I’ve spent years breaking down the construction, fabric density, and pocket placement that separates mediocre gym shorts from gear that actually performs under the barbell.
This guide analyzes seven top contenders to help you find the absolute shorts for crossfit that stay locked in place through box jumps, kipping pull-ups, and heavy cleans without sacrificing breathability or durability.
How To Choose The Best Shorts For CrossFit
CrossFit blends weightlifting, gymnastics, and monostructural work—each demands a different short behavior. The right pair balances freedom of movement with secure fit. Focus on these factors before adding to cart.
Inseam Length and Your Dominant Movement
A 5-inch inseam provides maximum hip and knee freedom for cleans and snatches, but may ride up during burpees. A 7-inch inseam stays planted during box jumps and wall balls, but can bunch under a squat belt. Test your typical workout split: gymnasts favor shorter cuts, lifters lean toward 7-inch for extra thigh coverage.
Fabric Weight and Snag Resistance
Lightweight woven polyester (under 5 oz) dries fast but may rip on a barbell knurl or Velcro knee sleeve. Mid-weight fabric (6-8 oz) balances breathability with abrasion resistance. Avoid cotton blends—they absorb sweat and chafe under load. Look for a small percentage of elastane (4-12%) for stretch recovery without sacrificing shape.
Pocket Configuration and Security
Standard mesh pockets dump a phone mid-double-under. For CrossFit, prioritize at least one zippered pocket—ideally on the back or side—that fits a modern smartphone without bulging. Avoid deep cargo pockets that flap during kettlebell swings.
Waistband Design and Drawcord
Flat knit waistbands with internal drawcords hold better through inverted movements. External cords that dangle can catch on a pull-up bar. A wide waistband (1.5-inch+) distributes pressure across the hips during Olympic lifting, preventing the shorts from rolling down during deadlifts.
Liner vs. No Liner
Lined shorts eliminate the need for compression underwear and reduce chafing—ideal for high-volume running or rowing. Unlined shorts give you control over your base layer and dry faster. Consider the 2-in-1 design for hot yoga and metcons where support matters more than weight.

In‑Depth Reviews
1. Anthem Athletics Isoflex Gym Shorts
The Anthem Athletics Isoflex hits the sweet spot of heavier fabric that resists barbell snags while remaining airy enough for a 400-meter run. Multiple users noted that the material feels thicker than budget gym shorts—a clear advantage when sliding on a plyo box or grinding through deadlifts. The metal zippers are a rare find at this tier and hold up far better than plastic alternatives under weekly wash-and-wear cycles.
The three inseam options allow a 5-inch cut for full hip mobility during snatches, or a 7-inch for athletes who want more thigh coverage during box jumps. The waistband features an internal drawcord that stays put during toes-to-bar and kipping movements—no external strings dangling near the rig. Customers with a 38-inch waist reported snug but comfortable fit with enough stretch to avoid pinch points.
The only minor drawback is color variation from product images—some buyers noted the two-tone option appears solid black in person. A single pocket seam tear was mentioned after repeated use on a second pair, but the majority of feedback over years of use describes these as the go-to short for heavy gym rotation.
Why it’s great
- Thicker, durable fabric resists barbell snags
- Metal zippers outlast plastic alternatives
- Multiple inseam lengths for different WOD styles
Good to know
- Color may appear different from product photos
- Pocket seam durability reported as inconsistent on some pairs
2. Nike Dri-Fit Flex Woven Shorts 7-Inch
The Nike Flex Woven is the ‘set it and forget it’ short—a dependable performer that does not try to reinvent the wheel. The Dri-FIT woven fabric is soft to the touch yet durable enough to survive repeated running and lifting sessions. Users report the elastic waistband with internal drawcord provides a secure hold without digging into the hips, even after years of rotation.
One dedicated buyer mentioned his husband has gone through four pairs, with each taking significant time to wear out—a testament to the fabric’s resistance to pilling and seam failure. The 7-inch inseam lands right in the Goldilocks zone for most CrossFit movements: short enough to avoid bunching under a belt, long enough to stay out of the way during high-snatch reps. The pockets are sized well for phone storage and do not flap.
The only limitation is the lack of a zippered security pocket, meaning a phone could slip out during explosive movements like box jumps or tuck jumps. The color options are the standard Nike palette—functional but not flashy.
Why it’s great
- Soft, durable woven fabric that withstands years of washing
- Ideal 7-inch inseam for lifting and running
- Secure elastic waistband that stays in place
Good to know
- No zippered security pocket for phone
- Limited color choices
3. Under Armour Launch Run 7-Inch Unlined Shorts
The Under Armour Launch Run is the ultimate lightweight unlined short for high-output metcons. The woven 100% polyester fabric is incredibly airy—multiple reviewers called it ‘thin but well made.’ The mesh side panels are a standout feature for rowing and running, dumping heat fast during high-rep workouts. The internal right-side phone pocket is a brilliant touch for tracking reps or tunes without the risk of dropping a device mid-WOD.
The soft knit waistband with internal drawcord eliminates the pinching often felt with external cords. One reviewer noted these shorts don’t ‘hang-up’ on leg day—the loose cut allows full bar path clearance for cleans and squats. The 7-inch inseam keeps the fabric from riding up during burpees, while the no-liner design means you can pair it with your preferred compression layer. The fabric also contains at least 90% recycled polyester, adding an eco-friendly element.
The waistband runs snug for larger waists, and the lack of stretch in the main body means you must size carefully. The mesh panels add extra seams that some users found unnecessary for a running short.
Why it’s great
- Mesh panels provide excellent ventilation for hot WODs
- Internal phone pocket keeps devices secure
- Lightweight and unlined for quick-dry performance
Good to know
- Waistband fits snug for larger sizes
- No stretch in main fabric—size up if between sizes
4. GYM REVOLUTION Men’s Workout Running Gym Training Shorts
GYM REVOLUTION shorts are engineered for high-temperature training environments—the lightweight, breathable material performs exceptionally well in Texas heat and similar climates. The deep zippered pockets are a standout feature, capable of holding a modern phone without bulging, even during explosive movements like box jumps or tuck jumps. The waistband stays locked in place without riding up, a result of smart internal grip design.
Multiple buyers praised the range of motion these shorts permit—the flexible material allows deep squats and lunges without restriction. The short inseam (shorter than expected) provides maximum hip clearance for Olympic lifts but may leave some athletes wanting more quad coverage for wall balls. The material shows no fading or shrinking after multiple wash cycles, maintaining its color and shape well.
The main concern is zipper durability—a few users reported the side zipper failing after several wears on some pairs. Loose threads appeared on one unit, suggesting batch inconsistency. For the performance per dollar, these remain a solid pick for athletes prioritizing pocket security above all else.
Why it’s great
- Deep zippered pockets secure phone and keys
- Lightweight, breathable material ideal for hot gyms
- Waistband stays in place without riding up
Good to know
- Zipper durability has been inconsistent
- Length may be shorter than expected for some athletes
5. Zero Foxtrot Athletic Zero Shorts – 5-Inch Inseam
Zero Foxtrot nails the swim-to-gym crossover concept without compromising on pocket security. The Athletic Zero features three zippered pockets (two side, one rear)—a configuration that eliminates the need to worry about loose change, keys, or a phone flying out during a double-under. The quick-dry fabric is solid without being flimsy, offering enough structure to hold its shape after multiple rounds of washing.
The 5-inch inseam provides maximum freedom for snatches, cleans, and gymnastics work, though athletes with larger thighs may find it a bit short for heavy box jumps. The fit is true to size, and the material has a comfortable hand feel that works for both training and casual wear. Multiple users noted the back pocket fits a wallet perfectly, making these an excellent option for athletes who go straight from the box to errands.
The drawstring length is a notable flaw—when untied it hangs to the knees, and when tied it can bunch up visibly under a T-shirt. The product description also omits key details about the back pocket, leading to surprise (positive) for new buyers but also reflecting a lack of thorough specs.
Why it’s great
- Three zippered pockets for total security
- Quick-dry fabric transitions from gym to swim
- Solid material that holds shape after washing
Good to know
- Drawstring is excessively long
- Short inseam may not suit athletes with larger thighs
6. Combat Iron Men’s Performance Training Shorts – 5.5-Inch
Combat Iron’s Performance Training Shorts deliver a unique combination of softness and mid-stretch allowance that makes them feel almost pajama-like while still performing under load. The 5.5-inch inseam splits the difference between gymnastic freedom and quad coverage, and the mid-stretch fabric allows a full range of motion without bagging out during sets. The mesh inner pockets add ventilation without adding bulk, though they lack the security of a zippered closure.
Buyers consistently praise the material quality—it’s soft to the touch yet durable enough for barbell work and general gym abuse. The veteran-designed branding resonates with a segment of the CrossFit community, and the fit runs true to size. One reviewer even repurposed these as swim trunks, noting the quick-dry fabric holds up to chlorine exposure.
The lack of zippered pockets means a phone or keys could bounce out during high-intensity movements, though the mesh pockets are deep enough to hold them during lighter WODs. The shorter inseam may not appeal to athletes who prefer more thigh coverage for box jumps or burpees.
Why it’s great
- Soft, comfortable fabric that still performs under load
- Mid-stretch allowance for full ROM without bagging
- Quick-dry construction works for gym and swim
Good to know
- No zippered pockets for phone security
- Short inseam may not suit all preferences
7. Swerve Men’s Lined Workout Shorts 7-Inch – 2-in-1
Swerve’s 2-in-1 lined shorts are purpose-built for hot yoga and inversion-heavy movements, but their construction translates well to CrossFit gymnastics. The interior mesh liner is a soft boxer-brief design that provides support without restrictive tightness—athletes can wear these without any added compression layer, which is a serious advantage for sweaty metcons. The wide waistband with internal drawcord stays planted during inversions and overhead work, eliminating the constant tugging that plagues cheaper lined shorts.
The 7-inch inseam offers generous quad coverage, and the fabric has a slight weight to it that resists tearing during barbell abrasion. The material dries quickly after a hot class, though long-distance runners reported some chafing risk on extended runs. The pockets are positioned to hold tissues or a phone, and the customer service is notable—one reviewer had their worn shorts accepted for exchange to find the right size.
The premium price point is the main barrier; these are the most expensive option here. For athletes who train hot yoga or gymnastics-heavy WODs, the built-in liner and stay-put waistband justify the investment. For strictly barbell training, a simpler unlined short might offer better value.
Why it’s great
- Built-in boxer-brief mesh liner eliminates need for compression underwear
- Wide waistband stays planted during inversions and overhead work
- Dries quickly and resists tearing
Good to know
- Premium price point—most expensive option
- May cause chafing on long-distance runs
