The Under Armour HeatGear® Compression Shorts are the original performance base layer built for warm-weather training. Crafted from super-light HeatGear® fabric, these men's compression boxers deliver an ultra-tight, second-skin fit that hugs your muscles and keeps you feeling cool, dry, and unrestricted no matter how intense the session. Whether you're running, lifting, or playing team sports, the moisture-wicking construction and strategic ventilation make these shorts the go-to foundation layer for any hot-weather workout.
HeatGear® — Under Armour's original performance fabric engineered for temperatures between 23 °C and 37 °C. It wicks sweat away from the skin rapidly and dries exceptionally fast, keeping you noticeably cooler even on the hottest training days.
Anti-Odor Technology — An advanced treatment prevents the growth of odor-causing microbes, so your kit stays fresh through even the longest sessions.
HeatGear® is Under Armour's original performance base layer fabric — the one engineered specifically for hot conditions between 23 °C and 37 °C. The super-light construction provides full-body coverage without the weight, so nothing gets in the way of your performance. The fabric wicks sweat away from the skin at a rapid rate and dries exceptionally fast, keeping you consistently cool and dry even during the most demanding sessions. It was the innovation that started it all back in 1996, and it remains the benchmark for warm-weather training layering today.
Strategically placed mesh panels are integrated into the garment's construction to deliver targeted ventilation exactly where heat and moisture build up most. The open-knit mesh structure promotes airflow across key zones, preventing overheating during high-intensity running, training, or field sports. Combined with the HeatGear® base fabric's wicking capability, the mesh panels create a two-tier cooling system that keeps internal temperature regulated from warm-up through to cool-down. The mesh sections use a 92% Polyester / 8% Elastane construction for a lightweight, breathable, and slightly stretchier feel.
Under Armour's Anti-Odor technology uses an advanced treatment applied directly to the fabric to prevent the growth of odor-causing microbes. Unlike perfume-based fresheners that merely mask unpleasant smells, this technology actively inhibits microbial activity at the source, meaning the shorts remain genuinely fresh through repeated hard workouts. The treatment is embedded into the fibers themselves, so it withstands regular machine washing without losing effectiveness. This makes the HeatGear® Compression Shorts a reliable companion for multi-sport training schedules where frequent washing is a given.
The ultra-tight, second-skin compression fit wraps closely around the muscles to enhance blood circulation, reduce muscle oscillation during impact activities, and help you feel more powerful throughout your session. The ergonomic design positions all seams away from high-abrasion zones — such as the inner thigh and waistline — to eliminate chafing and dramatically increase long-term durability. The updated gusset provides a full range of motion with maximum anatomical support, while the wide, exposed elastic waistband with the Under Armour wordmark sits firmly without rolling or digging in. The result is a compression short that disappears on the body so you can focus entirely on performance.
The proprietary Strength Pocket™ is positioned on the right side of the shorts, providing a secure drop-in storage solution for small essentials such as a key, card, or earbuds. The pocket opening is designed for fast, one-handed access without disrupting your stride or training rhythm. Its construction sits flush against the body to avoid bulk, maintaining the streamlined compression profile of the garment. This practical feature is particularly useful for athletes who use these shorts as a standalone garment rather than a base layer beneath outer shorts.
