base-layer - / beɪs-ˈleɪə / -
noun
The layer of clothes, closest to your skin. Its primary function is not to keep you warm but to keep you dry by wicking sweat away from the body. Ideally made of moisture wicking fabrics, natural fibres such as merino wool and silk perform this function well and have odour resistance properties. Synthetic materials, such as nylon and polyester tend to be really durable but may not be as planet friendly as you'd like.
\\ Your base layer looks perfect for these spring conditions - is it merino? Something like 190 GSM?
