Natural performance. Engineered for women.
Technical Workwear Made From Natural Fibres, Built to Endure.
Research shows up to 94% of women experience issues with the fit of their workwear.
Most workwear is still developed from a single base block and graded across sizes. The result? Women with very different proportions are often expected to wear garments built around one single body shape.
That's why we have built FitID.
Find your shape, learn about common fit issues, and discover how shape based workwear could improve fit.

Deep, functional pockets keep phones, tools, and essentials within reach, while reinforced panels at the knees, shins, and seat add protection in high-wear zones. The adjustable high-rise waist with elastic and button tabs stays secure through every lift and movement. Thoughtful details like dual cargo pockets, a hidden zip pocket, and calf ventilation zips ensure all-day comfort and utility. Flatlock seams provide lasting strength, and the natural fabric blend delivers breathability, durability, and ease of movement. Every stitch is built for performance — tough, practical, and made to move with you.
Natural Performance, Redefined.
Wool isn't just natural, it's revolutionary.
Temperature regulating, naturally flame-resistant, and moisture-wicking.
Wool outperforms synthetics in every metric that matters.
Threadline is pioneering the use of natural, high-performance materials in technical workwear. Our merino-blend fabric combines the durability needed for demanding work environments with the comfort and breathability that synthetic fabrics simply can't match.Unlike polyester that traps heat and odors, wool naturally regulates body temperature, resists flames, and stays fresh longer—reducing the need for frequent washing and extending the life of your garment.
