Used directly against the skin, a lightweight HeatGear fabric with four-way stretch and a smooth compression profile can reduce chafing and heat buildup within the first workout, provided the fit is snug (not restrictive) and seams sit flat in high-friction zones.
In this Under Armour compression shorts review, I break down what the product is designed to do, how it’s built, and who benefits most before getting into real-world testing, customer feedback, and comparisons later in the article.
In brief: These compression shorts aim to deliver close-to-skin support for training and running, prioritizing moisture control, friction reduction, and stable fit during high-output sessions.
Product overview
What these compression shorts are
The HeatGear Armour compression shorts are a staple training base layer from Under Armour, built to be worn alone or under outer shorts. They’re designed for warm-weather sessions and indoor training where sweat management and freedom of movement matter most.
Key construction elements
- HeatGear fabric: lightweight, breathable knit engineered to pull moisture away from the skin.
- Four-way stretch: allows unrestricted movement through squats, lunges, sprints, and lateral drills.
- Compression fit: supports muscles without feeling stiff when sized correctly.
- Flatlock seams: intended to minimize rubbing at the inner thigh and waistband.
- Elastic waistband: stays put during dynamic movement without rolling.
Intended use cases
These shorts are positioned as a do-everything compression layer for:
- Strength training and Cross-Training
- Running (road or treadmill)
- Team sports and conditioning
- Gym sessions where sweat control is critical
They are not padded, insulated, or weather-protective—this is a performance base layer, not a cold-weather tight.
Fit and sizing notes
Fit is true-to-size for a compression garment. A snug feel is expected; sizing up reduces compression benefits, while sizing down can feel restrictive. Inseam length typically lands mid-thigh, offering coverage without bunching.
My opinion after testing the Under Armour compression shorts
I tested the Under Armour HeatGear Armour compression shorts across several workouts: strength training, treadmill running, and high-intensity circuits. The goal was simple see how they perform when sweat, friction, and movement are all present.
Comfort and fit
From the first session, the fit feels secure without being restrictive. The compression is noticeable but not aggressive, which makes it suitable for longer workouts. The waistband stays in place, even during squats and dynamic movements.
Sweat management
Moisture control is one of the strongest points. Sweat is pulled away quickly, and the fabric dries fast between sets. Even after intense sessions, the shorts never felt heavy or sticky.
Chafing and movement
Flat seams do their job well. I experienced no inner-thigh irritation, even during runs. The four-way stretch allows full range of motion, and the fabric doesn’t ride up when moving.
Durability impression
After multiple washes, the material kept its shape and compression level. No loose threads, no fabric thinning overall, a reliable build quality for regular use.
Bottom line: these compression shorts deliver exactly what they promise comfort, breathability, and stable support without unnecessary features or gimmicks.
