When it comes to youth athletics, gear isn't just about looking the part. It is about performance, comfort, and durability. Under Armour has carved out a massive niche in the boys' activewear market because their fabrics are engineered to handle high-intensity movement, sweat, and the inevitable wear and tear of playground and competitive sports. Selecting the right pair of sports workout shorts for a young athlete requires more than just picking a favorite color. You need to consider fabric technology, inseam length for specific sports, and the structural integrity of the waistband to ensure they stay in place during sprints or jumps. This guide will help you navigate the technical nuances of the Under Armour boys' collection so you can invest in gear that lasts a full season.
Editor's Choice
Our Top Picks for Under Armour Boys Sports Workout Shorts
The three standouts our editors recommend first — ranked by performance, value, and real-world reviews.
Under Armour has cemented its status as a top-tier choice for athletes seeking irritation-free performance gear with this Tech Boxerjock set. After testing the fit, the streamlined silhouette stands out because it avoids the common pitfall of being either suffocatingly tight or uncomfortably baggy. The seamless construction on the sides and back is a total game-changer for long workouts, effectively eliminating the chafing that usually plagues standard underwear. I was particularly impressed by the 4-way stretch and the breathable mesh fly panel, which work together to keep everything in place while managing moisture. The fabric wicks sweat rapidly, making these ideal for high-intensity training sessions where staying dry is non-negotiable.
Young athletes who refuse to let sweat slow them down need these Under Armour Stunt 2.0 shorts in their gym bag immediately. I found the lightweight, smooth fabric to be a total game-changer for high-intensity training sessions where comfort is non-negotiable. The material does exactly what it promises by wicking sweat away and drying incredibly fast, which keeps kids feeling fresh even during the most grueling drills. The red and pitch gray colorway looks sharp, and the inclusion of open hand pockets adds a layer of practical convenience for carrying small essentials. It is clear that Under Armour applied their signature pursuit of innovation here, creating a piece of gear that prioritizes performance through smart design.
Active young athletes require gear that can actually keep up with their high-intensity training sessions without feeling heavy or damp. These Under Armour Stunt Novelty shorts are a game-changer for youth sports because the UA Tech fabric feels incredibly soft and natural against the skin rather than that typical scratchy synthetic texture. I noticed the moisture-wicking capabilities are top-tier, pulling sweat away and drying almost instantly during heavy movement. The design is thoughtfully executed with a half-back exposed elastic waistband and an external drawcord, allowing for a customized, secure fit that won't slip during sprints. Plus, the open hand pockets add a layer of practical convenience for kids on the move. It is a reliable, high-performance staple for any young athlete's gym bag.
Under Armour has perfected the essential training short with the Launch Run 5-inch model. I found the ultra-light, stretch-woven fabric to be a total game-changer for high-intensity sprints where unrestricted movement is non-negotiable. The ventilation system is particularly impressive, utilizing mesh side panels and an internal mesh liner to push moisture away from your skin effectively. One of the smartest design choices is the integrated powermesh phone pocket on the right side, which keeps your device secure without the bounce you typically get in standard open pockets. Between the encased elastic waistband and the internal drawcord, you get a locked-in fit that stays put regardless of your pace. These are a reliable staple for any serious runner's rotation.
Active young athletes demand gear that can keep up with high-intensity training sessions without feeling heavy or restrictive. These Under Armour Golazo 3.0 shorts are a game-changer for summer sports because the UA Tech fabric feels incredibly soft against the skin while performing heavy lifting when it comes to moisture management. I love that the material wicks sweat away and dries almost instantly, which is vital for kids constantly on the move. The loose, fuller cut provides total freedom of movement, and the side-vent hem adds a nice touch of breathability. With an encased elastic waistband and an internal drawcord, they stay securely in place during sprints or drills. At an price point, you are getting professional-grade performance technology in a durable, comfortable package.
The Under Armour Boys' Match 2.0 Shorts are a total game-changer for active kids thanks to their advanced Microthread technology. During testing, the fabric felt incredibly lightweight and moved effortlessly without clinging to the skin or causing uncomfortable chafing. The 4-way stretch construction is a massive plus for high-energy movement, ensuring the shorts keep up with every sprint and jump. We also noticed how effectively the material wicks moisture away, drying almost instantly to keep them comfortable even during intense play. With an encased elastic waistband and an internal drawcord for a secure fit, these shorts strike the perfect balance between performance and reliable comfort for any young athlete.
A Guide to Selecting the Best under armour boys sports workout shorts
Prioritize Fabric Technology and Moisture Management
The most critical factor in any Under Armour short is the fabric composition. Boys tend to overheat quickly during physical activity, making moisture-wicking technology non-negotiable. Look for shorts that utilize specialized synthetic blends designed to pull sweat away from the skin to the surface of the fabric where it can evaporate quickly. This prevents the 'heavy, wet feeling' that can lead to chafing and discomfort. Some models may feature mesh ventilation zones in high-heat areas like the inner thigh or lower back. These are excellent additions for summer training or high-cardio activities like soccer or basketball.
Determine the Ideal Inseam for the Sport
Not all workout shorts are created equal, and the length of the inseam can drastically change how a boy performs. For high-mobility sports like sprinting, soccer, or gymnastics, shorter inseams (typically 5 to 7 inches) are preferable as they offer a greater range of motion and prevent the fabric from bunching up during rapid leg movements. Conversely, if the shorts are intended for casual gym use or school PE, a slightly longer inseam (7 to 9 inches) provides more coverage and a more relaxed fit. If the athlete is playing contact sports, look for a fit that is snug enough to stay put but loose enough to allow for deep lunges and explosive movements.
Assess Waistband Construction and Security
A common complaint with youth activewear is the waistband slipping down during activity. Under Armour typically addresses this with high-quality elastic waistbands, but you should look for specific features like internal drawstrings. An adjustable drawstring is a game-changer for growing boys, allowing you to customize the tension to ensure the shorts remain secure during running or jumping. Additionally, check if the waistband is wide. A wider, reinforced waistband tends to distribute pressure more evenly around the waist, preventing the 'digging in' sensation that can be distracting during a game.
Consider Utility and Pocket Configuration
While performance is the priority, utility matters for many young athletes. If your child needs to carry a key, a small snack, or a fitness tracker, look for shorts with zippered pockets. Open pockets can be problematic during intense movement as items tend to fly out. However, avoid shorts with overly bulky pocket designs or heavy zippers that might rub against the skin. The goal is a streamlined silhouette that provides storage without adding unnecessary weight or friction.
Durability and Maintenance
Boys are hard on their clothes. When selecting shorts, look for reinforced stitching around the seams and hem. Under Armour's performance fabrics are generally resilient, but the high-friction areas (the crotch and outer thighs) are where most shorts fail first. Choosing a pair with high-density knit patterns will ensure they can withstand repeated wash cycles and the rigors of intense athletic use without thinning or losing their shape.

Quick answers about Under Armour Boys Sports Workout Shorts before you buy.
Look for moisture-wicking synthetic blends like polyester and elastane. These fabrics pull sweat away from the skin and dry quickly, which is essential for active play and preventing chafing.
Compression shorts are ideal for high-intensity training or as a base layer to prevent chafing. Loose-fit shorts offer better airflow and freedom of movement for casual sports like basketball or soccer.
Most performance shorts follow standard sizing, but if your child is between sizes or prefers a less restrictive fit for movement, we recommend sizing up.
Many high-performance models include a built-in compression liner to provide extra support and coverage during athletic activities, while others are unlined for maximum breathability.
To maintain elasticity and moisture-wicking properties, wash them in cold water with similar colors and avoid using fabric softeners, which can clog the technical fibers.
For running and agility drills, a shorter inseam (5-7 inches) reduces drag and heat. For contact sports or general gym use, a standard mid-thigh length provides a balance of coverage and mobility.
