ActiveIce Spectrum Sun T-Shirt - Men's

ActiveIce Technology is designed to help regulate your body temperature by reacting to heat. When you start to sweat or your body temperature rises, the fabric helps keep you cool by promoting evaporation. This is especially beneficial during activities like hiking or running in warm weather, as it helps you stay comfortable and focused on your performance.

A UPF rating of 50+ indicates that the fabric blocks at least 98% of the sun's harmful UV rays. This is crucial for protecting your skin from sun damage while you're outdoors. Wearing clothing with a high UPF rating allows you to enjoy your activities in direct sunlight with greater peace of mind regarding skin safety.

Moisture-wicking fabric is designed to pull sweat away from your skin and allow it to evaporate quickly. This keeps you dry and comfortable, which is particularly important during intense physical activities or in hot weather. By wearing moisture-wicking clothing, you can focus on your performance without the distraction of feeling sweaty or uncomfortable.

Stretch synthetic fabrics, made from materials like polyester and spandex, offer excellent flexibility and comfort. They stretch with your movements, allowing for a full range of motion during activities like climbing, running, or hiking. This means you can enjoy your outdoor adventures without feeling restricted by your clothing.

The center back length measurement indicates how long the shirt will be from the center of the back (from the neck down to the hem). A center back length of 28 inches, for example, gives you an idea of where the shirt will fall on your body. This measurement is important for ensuring a comfortable fit and achieving the desired style, whether you prefer a more relaxed or fitted look.

While ActiveIce Technology is primarily designed to keep you cool during warm weather activities, it can also be layered with other clothing for cooler conditions. If you're engaging in high-intensity activities that generate heat, wearing ActiveIce underneath a jacket or outer layer can help manage your body temperature effectively, keeping you comfortable throughout your adventure.
