The Alpha Core SL Base Layer was born from the fantastic warmth to volume/weight ratio and it’s ability to maintain warmth even when wet (and dry quickly). We are utilizing Polartec Alpha in strategically zoned applications across our Alpine and Vertex lines, and by creating a stand-alone base layer we’re able to bring the utility and fantastic warmth of this piece to any kit variation.
Layer for Maximum protection
Cold weather is probably the most common reason why cyclists opt to include a base layer. It provides an extra layer of insulation and pulls sweat from your skin, which will keep you dryer and warmer. That extra layer will also help hold warmth near the body.
