Our take on the Under Armour Men's HeatGear Compression Short-Sleeve Mock Neck Shirt

A men's short-sleeve compression base layer with a high mock neck, built from a polyester and elastane blend that stretches and wicks sweat. The tight, tapered fit sits close to the skin under jerseys, training tops or a uniform. It suits gym sessions, field sports and cold-weather layering. Rivals like Nike Pro and 2XU offer similar compression mocks, but Under Armour's HeatGear line is the most widely stocked and comes in sizes from XS to 4XL, which few competitors match.

Pros
  • Moisture-wicking HeatGear fabric keeps sweat off the skin
  • High mock neck adds warmth and coverage
  • Stretch blend moves with the body under load
  • Wide size run from XS to 4XL
  • Slim tapered cut stays flat under other layers
Cons
  • Very tight fit; size up if you dislike compression

  • Handwash and no-bleach care is fussier than most base layers
  • Short sleeves leave forearms uncovered for cold-weather use

Questions and answers

Should I size up in this compression mock?
Many owners say yes. The fit is genuinely tight and tapered, so if you are between sizes or dislike compression, go one size up.
Is it warm enough as a base layer in cold weather?
It adds a light insulating layer and the mock neck covers the throat, but the short sleeves leave arms exposed. It works best under another top or jersey.
Can I machine wash it?
The care label calls for a 30-degree handwash and no bleach. A gentle cold machine cycle is a common compromise, but follow the label to protect the elastane.
How does it compare with Nike Pro compression tops?
Both are tight, sweat-wicking base layers. Under Armour's mock neck and wider size range (up to 4XL) set it apart; Nike Pro is often cut slightly looser.
What is the fabric blend?
Polyester with about 16% elastane, which gives the stretch and recovery that compression wear needs.
Does it work for sports other than the gym?
Yes. It is used under rugby, football and baseball uniforms and for running in cool weather, thanks to the high neck and moisture wicking.
Where is the Under Armour Men's HeatGear Compression Short-Sleeve Mock Neck Shirt cheapest?
