Product Information

Full details

The Under Armour Tech Knockout Tank is designed for adult athletes and fitness enthusiasts who require a lightweight, breathable garment for high-intensity training and daily activity. Its primary benefit is the moisture-wicking, 4-way stretch fabric that provides maximum mobility and comfort; however, users should note that the lightweight material is quite thin, which may require careful layering or appropriate undergarment selection.

FAQs

Is this tank see-through?

The fabric is designed to be lightweight and breathable. While the darker colors offer full opacity, the lighter white variants may be slightly translucent depending on the undergarments worn.

Does the T-back design affect bra compatibility?

Yes, the T-back style may expose standard bra straps. We recommend pairing it with a racerback sports bra for the best aesthetic and support.

Can I put this in the dryer?

While it can be machine dried, we highly recommend air drying to keep the material soft and extend the lifespan of the performance fibers.

What is the primary material used?

This tank is made from high-quality, moisture-wicking synthetic polyester designed for athletic performance.

Does it run true to size?

The tank features a standard athletic fit. If you prefer a looser feel for your workouts, you may consider sizing up.

Troubleshooting

Fabric feels like it is losing elasticity

Avoid high heat in the dryer, as this damages the synthetic fibers. Always air dry.

Stains appearing on the fabric

Pre-treat with a mild sports detergent and wash immediately after use to prevent sweat-related odor or discoloration.

Pros and Cons

Pros

  • Extremely lightweight and comfortable fabric
  • Excellent moisture-wicking properties for intense exercise
  • High flexibility with 4-way stretch material
  • Stylish T-back design with branded taping
  • Fast-drying performance

Cons

  • Material is thin and may be slightly sheer in lighter colors
  • Hand-washing or delicate cycle is recommended for fabric longevity
  • Limited to athletic fit, may not suit those preferring loose-fitting tops

Setup, Compatibility & Care

This tank is a standard athletic top that functions best when paired with high-performance sports bras, as the T-back strap design may reveal traditional bra straps. To maintain the integrity of the 4-way stretch fabric and the wordmark taping details, it is recommended to wash the garment in cold water on a delicate cycle. Avoid using fabric softeners, as they can break down the moisture-wicking finish of the synthetic material. Hang drying is suggested to ensure the fabric remains soft and the shape is preserved over time.
