Tech 2.0 and HeatGear are both Under Armour's core training shirts, both use polyester-elastane blends, both market moisture-wicking performance, and they sit in similar price brackets. The differences are real but easy to miss in the marketing. Tech 2.0 is the modern softer-handfeel general-training tee. HeatGear is the heat-optimized cooling line with denser fabric and more compressive cut.
Most UA buyers default to Tech 2.0 because it is the most prominent line and the softer feel sells better in store. HeatGear is the right pick for specific use cases that Tech 2.0 cannot handle. We tested both lines extensively to map exactly when each one earns its place.

Pick Tech 2.0 If
- You want one shirt for daily training in moderate conditionsTech 2.0 handles 60 to 80 degree gyms perfectly, feels soft against the skin, and is the most versatile UA training tee. The default pick for most lifters.
- You want the shirt to also work for casual wearTech 2.0's softer hand-feel and more conventional cut allow it to pass as casualwear. HeatGear always reads as workout gear.
- Value matters and you buy multiple shirtsTech 2.0 at $25 on Amazon is the best dollar value in UA's lineup. Build a rotation in Tech 2.0 and add HeatGear pieces for specific use cases.
Pick HeatGear If
- You train in hot conditions or do summer runningHeatGear's engineered ventilation and faster wicking handle heat in a way Tech 2.0 cannot match. The temperature difference during long sessions in hot environments is meaningful.
- You want a fitted or compression silhouetteHeatGear runs more fitted and has dedicated compression versions. Tech 2.0 is loose-athletic and does not display the upper body the same way.
- You wash and wear the same shirts heavilyHeatGear's denser fabric and reinforced stitching survive more wash cycles. Better long-term value if you rotate through the same shirts daily.
Price & Value
Tech 2.0 prices at $25 to $32 on Amazon for short-sleeve crew. HeatGear short-sleeve runs $28 to $40 base, with compression versions reaching $50. Both lines run frequent sales (15 to 30% off). For daily training in moderate conditions, Tech 2.0 is the better value. For hot training or specific compression needs, HeatGear earns the small premium.
Final Verdict
Tech 2.0 is the right default for most UA buyers. It handles general training, feels good against the skin, comes in broad sizing and colors, and is meaningfully cheaper than HeatGear. Make Tech 2.0 the bulk of your UA wardrobe.
Add HeatGear for specific scenarios where Tech 2.0 falls short: hot-weather training, summer running, situations where you want compression, or daily heavy-rotation use where the durability premium pays off. The two lines complement rather than compete; most serious lifters end up with both in rotation.
