Linen material is a good absorbent of moisture and quickly removes the sweat from your skin. This is because of the fabrics molecular structure. Linen absorbs almost 1/5th of its weight before it starts becoming damp. This means that your linen shirt will never make you feel clammy. This is why in summer, your linen clothes are excellent cooling systems.
Linen material has anti-allergic properties and this is a crucial property for all clothes that are in direct contact with your skin. Skin rashes are always on the rise in summer and linen is safe to be worn out in the heat and prevents many skin allergies.
