Active Full Sleeve Tee | Series IV

INSIDE THE PRODUCT Ultralight. Highly Breathable. Built for Heat and Movement. The Active Full Sleeve Tee | Series IV is designed for active use in warm and hot conditions, combining an ultralight 100 g garment weight with a carefully engineered combination of two different fabrics. The front and back use 150 GSM poly-spandex mesh, made from 95% Polyester / 5% Spandex, providing high breathability and stretch where the body generates and releases the most heat. The sleeves use a lighter 135 GSM 100% Polyester fabric, keeping the arms lightweight while maintaining a clean, comfortable structure. With a Regular Fit, full sleeves and open hems, the Active Full Sleeve Tee is designed for travel, walking, outdoor activity and everyday wear when you want more coverage without adding unnecessary weight. Product Overview Purpose A full-sleeve active tee needs to provide coverage without trapping unnecessary heat. The Active Full Sleeve Tee | Series IV uses different fabric constructions across the body and sleeves to achieve that balance. The 150 GSM poly-spandex mesh across the front and back promotes airflow while the 5% Spandex provides flexibility during movement. The 135 GSM polyester sleeve fabric keeps the arms lightweight and comfortable. At just 100 g, the garment is designed to remain barely noticeable during wear, making it particularly suitable for hot-weather activity.
