When active outdoors, you need to manage your sweat to stay dry and comfortable, even when you stop moving. In hot conditions or working hard, you need maximum cooling; in cooler conditions you need less.
Sun protection is beneficial too. Parameta T+ fabric provides UV protection (SPF 25+ equivalent) and wicks moisture laterally to reduce pooling and enhance evaporation and cooling. The fabric also moves moisture from one face to the other, which, if directed away from you, offers greater insulation.
