Base layers are designed to keep you comfortable and dry. Many manufacturers make different base layers for different scenarios. We have seen moisture-wicking base layers produced by everyone from Nike and Adidas to Alpinestars and Dainese. With modern technology and research in textiles, we are now seeing base layers that can create a cooling effect as they evaporate moisture from your body, keeping you not just dry but also cool. Alpinestars Ride Tech Summer Long Sleeve base layer pictured above is offered in long sleeve tops, matching pants, and one-piece zip-up suits.
