The UNDER ARMOUR® men's HeatGear® Primo 9-inch core shorts feature a unique, patented X Band design that supports your core anatomy (hips, groin, pelvis, quads and hamstrings), while strategically angled 4-way stretch-woven fabric enhances functional movement, keeping your muscles locked in tightly. Moisture-wicking HeatGear® technology works hard to keep you cool, dry and light.

Key Specs:

  • Fabric Content: Body: 84% polyester, 16% elastane
  • Fabric Content: X Band: 87% polyester, 13% elastane
  • Inseam: 9 inches




  • Fit: Compression
  • 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.
  • Moisture-Wicking: Yes

  • Ergonomic Cut/Seaming: Yes
  • Seams and/or design lines of the garment follow the body's curves to allow freedom of movement and prevent skin irritation.

Additional Info

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.
