The Softest Wool T-Shirts

ultrafine merino (1)

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:

  • Fine grade (18.6 – 20μ)
  • Ultrafine grade (15.5μ and below)
  • Superfine grade (15.6 – 18.5μ)

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

Men’s Short Sleeve T-Shirts — Ultrafine Merino

Men’s Short Sleeve T-Shirts — Superfine Merino

A Merino T-Shirt from Outlier — this is the softest available at 15.5 microns

Men’s Long Sleeve T-Shirts – Superfine and Ultrafine Merino

More About Modern Merino Wool

Merino wool has come a long way since the scratchy, thick sweaters of our childhood.

Ultrafine merino wool also feels amazing against your skin – no more scratchiness. The fine fibers make for an incredibly soft fabric that drapes beautifully over your body, never clinging or catching on to anything.

These ultrafine merino wool shirts are perfect for active people who want to stay comfortable on the trail or at work.

Merino wool is a versatile material. It’s warm in cold weather and cool when it’s hot outside. This ability to regulate body temperature makes Merino ideal for outdoor activities like hiking, camping, and skiing.

One of the biggest advantages of ultrafine merino wool shirts is their moisture-wicking properties. Merino fibers can absorb up to 30% of their weight in water while still feeling dry. This means that sweat from your body won’t hang around on your skin but will instead be absorbed by the shirt where it evaporates quickly.

Another benefit of ultrafine merino wool shirts is their odor-resistance capabilities. Merino fibers have natural antimicrobial properties which prevent bacteria from growing on them. This means that you can wear a shirt several times before needing to wash it without worrying about smelling bad.
