1-Ply Extra Lightweight knitwear are suitable for Spring and Summer. They are made in a superfine 18-gauge weave. We source the same niche top-of-the line organic yarns that we usually use for luxury brands (that they sell for five times the price!) In the end, we selected Botto Giuseppe's superfine merino and Lineapelle's linen-silk. These organic materials are very breathable and more comfortable during summer heat than cotton. Unlike cotton, moisture and heat is able to conduct through merino, linen, and silk fabric, so it does not trap the odious feeling of heat or stickiness.
