Product Information

Full details

The Under Armour Tech Knockout Tank is designed for athletes and fitness enthusiasts who prioritize maximum airflow and range of motion during high-intensity training. Its standout benefit is the ultra-light, moisture-wicking fabric that ensures you stay dry and comfortable even during grueling workouts; however, the loose fit may be less ideal for those who prefer compression-style gear that stays close to the skin during inversions or complex movements.

Setup, Compatibility & Care

This tank is a standalone top designed to be worn over sports bras or on its own. To maintain the performance properties of the Tech fabric, follow these care instructions: wash in cold water with similar colors. Avoid using fabric softeners, as they can break down the moisture-wicking coatings on technical fabrics. Tumble dry on a low setting or, preferably, hang dry to preserve the shape and longevity of the T-back straps and elasticity of the fabric.
