Natural performance. Engineered for women.
Technical Workwear Made From Natural Fibres, Built to Endure.
The Fit Gap is costing women their place in the trades.
94% of women experience fit or comfort issues with their PPE (Safety Rack, 2024).
Most safety equipment and workwear — from seatbelts to stab vests — is still designed around men’s bodies, reflecting a systemic design bias. When ‘women’s’ versions are made, they’re often just scaled down — with smaller, shallower pockets that don’t fit tools or essentials.
When your workwear doesn’t fit, it’s harder to move safely, stay comfortable, and feel like you belong. Many women leave the industry because constant discomfort and safety risks make every job harder than it should be.

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.
