Lined versus unlined gym shorts represent a major gear choice for athletes, according to equipment testers and fitness editors at Men’s Health. Quality training shorts typically cost between $50 and $80, making it essential to understand whether built-in compression liners or traditional unlined styles fit your routine before buying. While Big Fitness has popularized built-in compression to eliminate separate underwear and add mid-thigh support, many runners and lifters prefer the flexibility of standard shorts paired with independent base layers.
The Core Differences Between Lined and Unlined Training Shorts
Lined shorts feature built-in underwear, usually constructed as breathable compression shorts, mesh, or briefs that extend toward the mid-thigh. According to Men’s Health gear testers, this extra support prevents chafing during high-friction activities like running, plyometrics, or intense air bike sessions. Brands vary their liner designs significantly, offering everything from locked-in compression to looser mesh briefs.
Unlined shorts leave the choice of undergarments entirely to the wearer. According to Men’s Health Fitness and Reviews Editor Charles Thorp, NASM, unlined styles offer greater versatility for everyday errands. “I wear both, but I think when it comes to unlined, I like that I can hit a quick workout but also do some errands after without feeling like I’m wearing ‘gym shorts’ at the grocery store,” Thorp states. This setup allows athletes to cycle through different base layers depending on whether they are golfing, running, or powerlifting.
How to Choose the Right Gym Shorts for Your Workout Style
Deciding between the two styles depends heavily on your primary training modalities. High-friction, high-impact movements such as sprinting, trail running, or box jumps benefit greatly from a tight liner that keeps everything secure and minimizes sweat-induced chafing. Heavy sweaters prone to skin irritation often find relief in dedicated compression liners.
Conversely, static training sessions like heavy barbell lifting or walking require less intense containment. Lifters who dislike the restricted feel of built-in compression often purchase unlined shorts and layer them over their preferred, independent compression shorts. This modular approach provides complete control over fit and fabric performance.
Pro Tip: If you run long distances or sweat heavily, prioritize lined shorts with longer compression liners to eliminate inner-thigh friction. For mixed days involving lifting and casual errands, unlined shorts paired with a separate waistband offer maximum versatility.
Top-Rated Lined Gym Shorts for Runners and Cross-Trainers
Athletes searching for all-in-one performance gear have several standout options backed by editorial testing:
- Vuori Kore Shorts: Founded in 2015, Vuori crafts these popular athleisure shorts using a recycled polyester-elastane blend. Available in 5-, 7-, and 9-inch inseams, they feature two front pockets and one rear pocket. Men’s Health editors award them top marks for aesthetics, noting they transition easily from the gym to casual lunch spots.
- Hoka Glide 2-in-1 Shorts: Featuring a 7-inch inseam and a longer compression-style liner, these shorts target runners and plyometric athletes needing thigh coverage and anti-chafe support. They incorporate a secure mesh storage system and a discreet zip pocket for phones and keys.
- Roark Alta Shorts: Built specifically for trail runners, the Alta utilizes a 3.5- or 5-inch inseam with a loose brief liner and a water-resistant zippered phone pocket. Four-way-stretch fabric and antimicrobial treatments keep long-distance runners comfortable and fresh.
- Tracksmith Cannonball Shorts: Designed for dual duty as running shorts and swim trunks, these lightweight shorts feature a supportive, lightweight liner, a credit card pocket inside the liner, and a bungee cord anchor in the front pocket for keys.
Top-Rated Unlined Gym Shorts for Maximum Versatility
For athletes who prefer choosing their own base layers, editorial testing highlights these durable unlined choices:
- Rhone Pursuit Shorts: Available in 5-, 7-, and 9-inch inseams with side pockets and a stealth zipper pocket, the Pursuit utilizes a lightweight polyamide-elastane fabric. Editors rate them as highly versatile for everyday wear, lifting, and running errands.
- Lululemon Pace Breaker Shorts: Dubbed the “unicorn” of gym shorts by the Men’s Health team, these feature a mesh back panel for airflow, two front pockets, and a secure zippered pocket. Testers logged dozens of miles running and lifting in them, praising their secure waistband and extensive color range.
- The Warren Shorts: Made with water-resistant material and deep zippered pockets large enough for modern smartphones, the Warren offers an anchored drawcord that prevents the drawstring from disappearing into the waistband during washing.
Home Versus Gym Workouts: Finding Your Training Environment
Beyond gear selection, modern fitness routines require deciding where to sweat. According to Sports Direct training ambassador Emma Kirk-Odunubi, a sports scientist, runner, and coach, the post-pandemic landscape split fitness routines between home living rooms and reopened commercial facilities. Neither environment holds a universal crown; success depends entirely on individual lifestyle constraints, goals, and energy levels.
Gym workouts offer full access to heavy equipment like barbells, sleds, and cable machines, alongside expert in-person coaching and a motivating social environment. However, membership costs, travel time, and peak-hour crowds can present barriers. Home workouts excel in convenience, making quick 20-minute circuits or mobility sessions highly efficient for busy schedules, though they lack specialized heavy load equipment.
