The Softest Wool Shirt For 2021

In terms of fineness, any wool fiber that has a diameter of 20µ (microns) or less will feel very soft to the touch.

Below 17.5µ the wool starts to feel buttery soft against the skin.

Here’s a guide to fineness grading:

These are the finest wool T-shirts I’ve found:

Men’s Short Sleeve T-Shirts — Ultrafine Merino

Glossary

g/m² — grams per square inch (the weight of wool in the garment)

wool percentage — the actual amount of ultrawarm fiber in the garment — I don’t feature anything here with less than 50% ultrawarm wool

micron — the symbol “μ”– one million of a meter — the diameter size of the hair in the wool — also known as “fineness”
