Base Layers

The layers under a garment are very important to help keep you comfortable in both hot and cold climates (as they can help warm or cool you). They are far more comfortable than wearing a regular cotton t-shirt (which can get damp with sweat rather than wick away the moisture) or a sweatshirt which is often just way too thick and uncomfortable. They also add a level of hygiene as they are more easily washable than the whole garment.
