Aerobora Short-Sleeve Shirt - Men's

UPF Rating stands for Ultraviolet Protection Factor, which measures how much UV radiation can penetrate the fabric. A higher UPF rating means better protection from harmful sun rays. For example, a shirt with a UPF rating of 25 allows only 1/25th of the sun's UV rays to reach your skin, making it an excellent choice for outdoor activities.

A performance-rated shirt is specifically designed with features that improve comfort and functionality during activities like hiking or climbing. These shirts often include moisture-wicking properties, breathability, and stretch, ensuring you stay comfortable and agile while enjoying your adventures.

Synthetic materials, such as polyester, are engineered to be lightweight, durable, and moisture-wicking. This means they dry quickly and help keep you dry during physical activities, making them ideal for outdoor wear. Unlike natural fibers, synthetic fabrics can also resist wrinkles and maintain their shape over time.

AirExchange Performance is a technology that enhances the breathability of the fabric. It allows air to circulate more freely, helping to regulate your body temperature and keep you cool, especially in warm weather. This feature is particularly beneficial during strenuous activities, ensuring you remain comfortable throughout the day.

Absolutely! A button-up style shirt is versatile and can be dressed up or down. It’s perfect for casual outings when paired with shorts or jeans, and can easily transition to a more formal setting when worn with chinos or dress pants. This makes it a great addition to your wardrobe for various occasions.

To find the right size, refer to the sizing chart provided on the product page. Measure your chest, waist, and hips, and compare those measurements to the chart. Performance-rated shirts are often designed with a slightly athletic fit, so if you prefer a looser fit, consider sizing up.
