Under Armour HeatGear Short Sleeve - Blue / White - L

Yes, it is designed as a performance baselayer but is frequently worn on its own during intense athletic activities.

While the fabric provides coverage, it is not explicitly rated for UPF protection; you should apply sunscreen for outdoor activities.

It is not designed as swimwear. Chlorine and salt water may damage the technical fabric fibers over time.

The garment is constructed from high-quality, durable polyester engineered for performance.

It features a compression fit, which should feel snug against your skin to help with muscle support and moisture-wicking.

The mesh is strategically placed in low-friction areas, but handle with care when putting the shirt on to avoid catching fingers on the weave.

Ensure you have selected the correct size; HeatGear is designed as a compression fit. If you prefer more room, consider sizing up.

Ensure you are not using fabric softener and consider using a sports-specific laundry detergent designed to break down sweat oils.

Wash the shirt inside out and avoid washing it with rough items like denim or items with heavy zippers to prevent surface friction.
