Benefits to look for:

Moisture Wicking--

Visa is hydrophilic. It wicks perspiration away from the skin, moving moisture to the outer surface of the garment, where it evaporates.

Unimproved polyester is hydrophobic. It has a chemical attraction to sweat and oily dirt, trapping moisture next to the skin.

Soil Release--

Skip the pretreatments. Visa is machine washable, releasing stubborn stains and odors without pretreatments.

Unimproved polyester traps stains and odors. Over time, the look and smell of unimproved polyester activewear deteriorates significantly.

Prevents Soil Redepositation--

Visa prevents dirt and oil transfer inthe wash cycle. With no soil redepositation, Visa colors stay bright and whites stay white, wash after wash.

Unimproved Polyester picks up dirt and oil in the wash cycle. This explains why colors become dull and whites turn gray over time.
