Undyed Merino Wool Thermal Long Sleeve for Men

This undyed merino wool thermal long sleeve is made for those who work with natural and plant-based dyes.

Produced from 100% merino wool and left completely undyed and untreated, this garment provides a clean, neutral base for natural dyeing applications. Merino wool’s fine fibers absorb natural dyes evenly, allowing for rich, soft, and long-lasting color results.

The fabric is free from chemical dyes, bleaching agents, and synthetic finishes. This makes it suitable both for dye testing and for daily wear after dyeing. Once dyed, it can be worn directly as a thermal inner layer, offering natural warmth, breathability, and comfort.

Designed for men, this long sleeve thermal top can be dyed using traditional plant dyes, roots, leaves, bark, and mineral-based mordant systems. Ideal for artisans, designers, workshops, and individuals who want to dye and wear their own naturally colored garments.
