Linen is the best fabric because it’s a very light and cool fabric. It also absorbs the heat very well. The Linen Guayaberas are very cool, fresh and elegant. They have style, travel with ease and about the sweat marks we recommend wearing an undershirt for protection. Most of the fabrics will tend to absorb the sweat. Again the dress etiquette for beach weddings is more relaxed because of the afore mention factors. Other fabrics that can handle the heat well are silk and chiffon.
