Product Information

Full details

The Under Armour Project Rock Iso-Chill Tank is designed for adult athletes and gym-goers who require high-performance apparel during intense training sessions. Its primary benefit is the specialized Iso-Chill fabric technology, which actively disperses body heat to keep the wearer cool throughout a workout. While the tank offers exceptional breathability and freedom of movement, users should note that the generous dropped armholes provide a very loose fit that may not be suitable for those preferring a more traditional, form-fitting athletic cut.

FAQs

What is Iso-Chill technology?

Iso-Chill is a unique fabric technology that helps disperse body heat, making it feel cool to the touch while you are wearing it.

Is the fit true to size?

The tank features a loose, athletic fit with deep armholes, which is intended to be roomy. If you prefer a tighter fit, you may want to consider sizing down.

Can I use this for running?

Yes, the moisture-wicking and breathable properties make it suitable for running, though it is primarily styled for training.

Does the mesh back get damaged easily?

The mesh is reinforced, but it is a lighter-weight fabric than the front. It is recommended to handle it with standard care in the wash.

Is this tank see-through?

The front fabric is opaque, while the back mesh is designed for high ventilation, which may be more transparent due to its weave.

Troubleshooting

Fabric feels less cool after multiple washes

Ensure you are not using fabric softeners, as they can coat the fibers and interfere with the Iso-Chill cooling technology.

Snagging on equipment

While the fabric is durable, avoid contact with rough surfaces like concrete or sharp gym equipment to prevent pulling the mesh back panel.

Pros and Cons

Pros

  • Excellent heat management in hot environments
  • Highly breathable mesh back panel
  • Fast-drying material reduces discomfort during long workouts
  • Great mobility due to 4-way stretch and wide armholes

Cons

  • Dropped armholes may be too revealing for some users
  • Loose fit might not provide the compression feel some athletes prefer
  • Limited to specific, casual aesthetic

Setup, Compatibility & Care

To maintain the performance of the Iso-Chill technology and the durability of the stretch fibers, follow these care instructions:

  1. Washing: Machine wash cold with similar colors. Avoid using bleach, which can damage the moisture-wicking properties.
  2. Drying: Tumble dry on low heat. High heat may degrade the elasticity of the 4-way stretch fabric over time.
  3. Ironing: Do not iron. The material is designed to be wrinkle-resistant and heat can alter the fabric finish.
  4. Storage: Hang to dry or store flat to preserve the shape of the dropped armholes.
