The difference between a good leg day and a great leg day often comes down to one piece of fabric — the right pair of shorts. Too loose and you’re fighting bunching under the barbell. Too stiff and every squat feels like a battle against the seam. Gym shorts for men have evolved past basic cotton blends, and the modern options now demand attention to fiber type, inseam length, and ventilation mapping if you want to actually enjoy moving heavy weight.

I’m Mohammad — the founder and writer behind ProteinJug. I’ve spent the better part of a decade analyzing what separates a short that survives 500 wash cycles from one that pills after a month, digging into fabric weight, moisture-wicking chemistries, and the real-world durability of stitched seams versus welded hems.

This guide breaks down five top-tier options across unlined, lined, cargo, and tech fabrics, with every spec tied back to how it performs under a loaded barbell or on a hot treadmill. You’re here because you want the single best pair of gym shorts for men that won’t hold you back on any lift.

How To Choose The Best Gym Shorts For Men

Gym shorts look simple, but the wrong choice can sabotage your training session before the first set. The fabric’s ability to pull sweat away from your skin, the inseam’s effect on your hip mobility during a deep squat, and the presence of a liner all dictate whether you leave the gym dry and comfortable or soaked and chafed. Focus on three core factors before you buy.

Fabric Composition and Weight

Polyester dominates modern gym shorts because it dries fast and resists mildew. Look for 100 percent polyester or a polyester-elastane blend if you need a touch of four-way stretch. Avoid cotton-dominant blends for intense sessions — cotton holds moisture like a sponge, soaking up sweat and leaving you heavy and cold. A lightweight fabric around 100 to 130 GSM (grams per square meter) offers the best airflow for high-output training.

Inseam Length and Mobility

The inseam directly dictates how much fabric you have to manage during movement. Seven-inch inseams hit above the knee for most men — ideal for unrestricted hip flexion during squats and deadlifts. Ten-inch inseams hover near or below the knee, offering more coverage and a traditional look but can bunch up during deep bends. If you prioritize range of motion, go shorter. If you prefer modesty or have long thighs, the longer cut works better.

Lining and Pocket Design

Unlined shorts give you freedom to wear your own compression briefs or go commando, and they generally dry faster. Lined shorts integrate a built-in brief — convenient for quick runs but can feel restrictive for some body types. Pockets should stay flat and low-profile. A zippered pocket or an internal phone sleeve prevents your device from flopping around during explosive movements like box jumps or sprints.

In‑Depth Reviews

Best Overall

1. Fabletics The Fundamental Short II (Lined)

Built-in linerUltra lightweight polyester

The Fabletics Fundamental Short II uses an ultra lightweight polyester shell with an integrated mesh brief liner, giving you the support of compression shorts without the weight of a separate layer. Reviewers consistently note the fabric feels substantial enough not to go sheer under stretch, a common failure point on cheaper lined shorts. The liner itself provides a secure cradle for the groin area, reducing bounce during high-rep jumping movements and sprints.

Pocket design here is smarter than most — the side pockets are deep enough to hold a phone without it flopping out when you go into a full sprint, yet the material lies flat enough to stay unobtrusive during barbell work. Multiple customers report that sizing runs slightly smaller than standard athletic brands, so ordering one size up is a common recommendation, especially for guys with larger quad development.

The 7-inch inseam hits right above the knee for most frames, giving excellent hip clearance for deep squats while still offering enough coverage for those who prefer not to show too much thigh. The antimicrobial treatment on the liner also helps manage odor during long sessions, a detail that becomes noticeable after repeated wash cycles without fabric softener.

Why it’s great

  • Integrated liner eliminates the need for separate compression briefs
  • Ultra lightweight polyester wicks sweat rapidly and dries in minutes
  • Deep, low-profile pockets keep phone secure during explosive moves

Good to know

  • Sizing runs small — consider going one size up
  • Built-in liner may feel restrictive for men who prefer unlined freedom

2. Under Armour Men’s Launch Run 7 Inch Unlined Shorts

Unlined meshInternal phone pocket

The Under Armour Launch Run shorts prioritize airflow above everything else. The main body uses a lightweight woven polyester that feels almost paper-thin in hand, but the mesh side panels are where the magic happens — those inserts dump heat aggressively, making these a top pick for high-intensity interval training or outdoor summer runs. The fabric also incorporates at least 90 percent recycled polyester, which doesn’t come at the cost of durability based on long-term reviewer feedback.

A standout feature here is the internal phone pocket sewn into the right-hand side. Unlike many shorts that rely on a loose mesh sleeve that lets a phone shift, Under Armour stitched a snug sleeve that keeps a modern flagship phone pinned flat against your thigh, eliminating the swing effect that throws off your stride. The open hand pockets are deep enough for cards and keys but stay shallow enough to prevent fabric flop during leg raises.

The 7-inch inseam combined with the unlined cut gives total freedom of movement — no liner means you can wear your preferred briefs or compression tights underneath without any double-layer bunching. The waistband uses a soft knit construction with an internal drawcord, and reviewers with waists up to 38 inches report the regular fit accommodates without digging in, though some noted the waistband runs slightly snug at the upper end of the size range.

Why it’s great

  • Mesh side panels deliver exceptional ventilation for hot sessions
  • Internal phone pocket locks device in place during running
  • Unlined design lets you wear your own compression layer

Good to know

  • Waistband can feel snug for larger waist measurements
  • Thin fabric may show sweat marks more prominently

3. Under Armour 7″ Tech Vent Shorts

Quick-dry knitUnlined stretch waist

The Under Armour Tech Vent 7-inch shorts sit in the sweet spot between pure running shorts and all-purpose training gear. The fabric is a lightweight knit polyester that stretches in four directions, giving you the freedom to drop into a full-depth squat or lunge without any resistance at the hip crease. Unlike the Launch Run, these shorts skip the mesh paneling in favor of a uniform knit that still breathes well but offers a slightly denser feel that resists snagging on gym equipment.

Reviewers who practice kickboxing and mixed martial arts praise these shorts for their freedom of movement during high kicks and sprawls — the unlined cut and generous gusset allow full hip rotation without fabric binding. The waistband uses Under Armour’s soft knit elastic with an internal drawcord, and multiple users report zero shrinkage or fading after machine washing and drying over the course of a full year of weekly use.

The pocket situation is more basic here compared to the Launch Run. Open hand pockets are present but lack a zipper or internal phone sleeve, which means your phone can slide out during explosive movements like burpees or box jumps. Several customers flagged this as the only real weakness, especially for those who rely on music or coaching apps during training. If you carry a phone, a zip-up armband or waist pouch solves the issue neatly.

Why it’s great

  • Four-way stretch fabric moves with you through full-range lifts
  • Durable knit survives weekly washing without shrinking or fading
  • Unlined design offers unmatched freedom for martial arts training

Good to know

  • Open pockets lack a secure closure for phones
  • Knit fabric can feel a bit warmer than mesh-paneled alternatives

4. Under Armour Men’s Tech Graphic 10″ Shorts

10-inch inseamMoisture-wicking loose fit

The Under Armour Tech Graphic 10-inch shorts cater to lifters who want more coverage without sacrificing the sweat-wicking performance of a technical fabric. The longer inseam extends below the knee for most men, providing a traditional gym-shorts silhouette that feels more appropriate for weightlifting floors where modesty is a concern. The loose fit through the leg gives plenty of room for thick quadriceps to move freely without the fabric sticking or riding up.

Fabric composition here matches the Tech line — a lightweight polyester blend that pulls moisture away from the skin rapidly. Reviewers confirm the material keeps them dry during heavy sets, though the longer cut means there is more fabric overall, so heat dissipation is slightly slower than the 7-inch alternatives. The elastic waistband with drawcord stays secure even under the stress of dynamic movements like kettlebell swings or box step-ups.

Pocket depth is a genuine plus point for the Graphic 10-inch. The side pockets are deeper than many competitor offerings, holding a phone securely without it peeking out. The graphic print on the leg adds a casual aesthetic that transitions well from the gym floor to running errands, though some customers noted the print can crack slightly after repeated machine drying — hang drying is recommended to preserve the graphic finish.

Why it’s great

  • 10-inch inseam provides below-knee coverage preferred by many lifters
  • Loose cut accommodates larger quads and glutes without restriction
  • Deep pockets keep phone and keys secure during training

Good to know

  • Longer fabric can feel warmer during intense cardio sessions
  • Graphic print may crack if dried in high heat repeatedly

5. adidas Originals Men’s Essentials Small Logo Cargo Chelsea Shorts

Cargo pocketStretchy polyester blend

The adidas Originals Cargo Chelsea Shorts take a different approach — they blend gym-ready stretch polyester with a casual cargo aesthetic that doubles as everyday wear. The fabric has a soft, almost cotton-like hand feel but retains the moisture-wicking and quick-dry properties of true performance polyester. The extra cargo pocket on the leg is sized to fit a tennis ball or phone, making these shorts genuinely useful for functional training where you need to carry small implements.

Reviewers with larger builds, including a customer who described his teenage son as “built like a linebacker,” report that the large-tall sizing accommodates muscular thighs and longer torsos without giving a balloon-like silhouette. The shorts hit slightly above the knee for most heights, though several shorter reviewers noted they ran a bit longer than expected. The elastic waistband with drawcord keeps the fit adjustable without feeling restrictive.

The biggest trade-off here is the stretch polyester blend is slightly heavier than the pure woven options from Under Armour or Fabletics, which means it breathes less aggressively during high-heat training sessions. These shorts shine best in a mixed-use scenario — morning gym session followed by errands or casual social time — rather than dedicated competition-level training. Also worth noting the pockets, while generous, lack zippers, so keys can migrate during intense movement.

Why it’s great

  • Cargo pocket adds practical storage for gym implements and daily carry
  • Stretchy polyester blend feels soft and comfortable for all-day wear
  • Tall sizes available for athletes with longer inseam requirements

Good to know

  • Fabric runs slightly heavier and less breathable than pure running shorts
  • No zippered pockets — smaller items can shift during active movement

FAQ

What is the best inseam length for squatting?
A 7-inch inseam gives the best range of motion for deep squats because it keeps fabric above the knee, preventing the hem from catching under the knee cap during the descent. Lifters with longer femurs may still find a 5-inch or 6-inch short more mobile, while those who prioritize coverage may tolerate slight bunching from a 10-inch pair.
Should I buy lined or unlined gym shorts?
Choose unlined if you wear compression briefs, boxer briefs, or have a strong preference for a specific brand of underwear — this gives you total freedom and faster drying. Choose lined if you want a single-piece system that provides built-in support and eliminates the need to pack separate underwear for quick gym sessions.

Final Thoughts: The Verdict

For most users, the gym shorts for men winner is the Fabletics The Fundamental Short II because the integrated liner delivers support without adding weight, and the ultra lightweight fabric keeps you dry through the toughest circuits. If you prefer an unlined cut for maximum freedom of movement, grab the Under Armour Launch Run 7 Inch. And for lifters who need longer coverage and deeper pockets for daily carry, nothing beats the Under Armour Tech Graphic 10″.
