There are several types of base layers available, each offering unique features and benefits to cater to different activities and weather conditions. Synthetic base layers, often made from materials like polyester or nylon, are known for their durability, moisture-wicking properties, and quick-drying capabilities, making them ideal for high-intensity activities and warmer temperatures. Merino wool base layers are popular for their natural odor-resistance, temperature regulation, and soft, comfortable feel against the skin, making them suitable for a wide range of outdoor activities in varying climates. Additionally, blended base layers combine the benefits of synthetic and natural fibers, offering a balance of performance and comfort for outdoor enthusiasts.
