Moisture-wicking HeatGear® technology works hard to keep you cool, dry and light.

  • Supports your muscles to prevent fatigue during intense training.
  • Fabric Type: Stretch
  • Usually a blend of knit or woven fabric with spandex or elastane. Creates a soft, durable fabric which allows freedom of movement yet retains its shape through repeated wash cycles.

    Comments about UNDER ARMOUR Men's HeatGear Primo 9-inch Core Shorts:

    Bought both these and the regular Under Armor Heat Gear shorts, ending up keep the regular ones. I was purchasing these hoping for extra support for my hamstring but found them to simply be more uncomfortable with little added support. I would stick with the regular Under Armor Heat Gear.
