Rab Mens Syncrino Base Long Sleeve Baselayer


All about this product



The Syncrino Base Long Sleeve Tee is the ultimate choice for those seeking comfort and performance in cold mountain environments. Crafted from Rab's innovative Syncrino 125 fabric, this long-sleeve tee is a harmonious fusion of breathability, skin-friendly softness, and remarkable stretchiness. It serves as an ideal first layer for cold-weather mountain climbing, offering superior odour resistance and quick-drying capabilities, making it equally suitable for extended adventures.


The fabric's composition is a testament to its excellence, combining the natural advantages of Merino wool with the durability and quick-drying properties of 32% recycled synthetic fibers. Merino wool, renowned for its cold-weather suitability, excels in moisture absorption, effectively wicking away sweat and ensuring comfort while regulating body temperature. Even when wet, it retains its insulating properties, though drying may require some patience.


Complementing the Merino wool, the synthetic fibers offer robustness, lightweight performance, shape retention, and rapid drying. The blend of these materials yields a fabric that is not only quick-drying and moisture-wicking but also exceptionally insulating and durable, making it the perfect choice for base layers in mountainous conditions.
