Girls' sportswear designed to keep young athletes comfortable and dry during exercise, the Under Armour Girls' Knockout Tank combines soft, breathable fabric with a loose fit. Confidence for PE lessons, clubs and casual wear comes from quick-dry material and anti-odour protection. Is this the most practical choice for active youngsters who need fuss-free gymwear?

⚡ At a Glance
  • Wearing Comfort: Soft, breathable fabric with a loose fit that reduces restriction during activity
  • Best for: Active girls who need breathable, low-maintenance gym and training wear
  • Not ideal for: Those who prefer a compressive or performance-fit top

Lightweight polyester-elastane blend with a loose fit and breathable construction. Anti-odour technology and quick-dry properties help keep the top fresher between washes.


Freedom of movement – thanks to 4-way stretch construction

Four-way stretch construction allows the fabric to extend and recover across multiple directions, reducing resistance during dynamic motion. The elastane content provides recovery so the shape holds up through activity.

Unrestricted movement suits running, PE drills and gymnastics without fabric pulling or restricting motion.

Moisture management – with sweat-wicking, quick-dry fabric

Sweat-wicking fibres pull moisture away from the skin and the quick-dry finish speeds evaporation, helping the fabric dry faster after heavy activity. Breathable construction aids airflow during exercise.

Keeps youngsters drier and more comfortable during and after workouts, reducing chill when cooling down.

Longer freshness between washes – thanks to anti-odour technology

Anti-odour treatment inhibits the growth of odour-causing microbes on the fabric surface, helping the garment resist unpleasant smells longer.

Allows more wear between washes and keeps kit smelling fresher during a busy week of activities.
