SilkCut Underwear | Engineered for Comfort & Performance

Innovation You Can Feel

At SilkCut Underwear, we believe that true luxury begins at the microscopic level — in the fiber, the yarn, and the weave. Every SilkCut fabric is developed through technological innovation, refined engineering, and precision finishing. Our partners, including Willy Hermann – SUPERFINE® and Lenzing™, set the global standard for ultra-fine yarn spinning and sustainable production.

Technological Leadership

SilkCut invests in high-gauge circular knitting machines and air-jet looms capable of handling fibers finer than a strand of silk. These machines operate with exceptional accuracy, producing fabrics that are thinner, lighter, and smoother than cotton or bamboo. Our R&D partners collaborate directly with textile machine engineers to bring new spinning, knitting, and finishing techniques to life.

The result is a line of fabrics that consistently rank among the most advanced in the world — blending scientific performance with timeless design. Customers around the world choose SilkCut not only for the comfort they feel, but for the innovation woven into every thread.

Our Fabric Technologies

Each SilkCut fabric is a study in materials science — combining micro-engineered yarns, eco-conscious sourcing, and next-generation machinery to redefine comfort.

Micro Modal Air® — The Pinnacle of Fabric Innovation

Micro Modal Air® represents the highest level of advancement in the world of natural performance fabrics. Developed by Lenzing™ in Austria, it is crafted from renewable beechwood pulp using an eco-certified closed-loop process that reuses 99.6% of solvents and water. Each filament has an average diameter of just 0.8 dtex—significantly finer than silk or cotton fibers— allowing unmatched softness, breathability, and durability.

Woven on high-gauge seamless knitting machines, Micro Modal Air® features a dual-layer micro-weave structure: a smooth outer surface that resists pilling, and a soft inner layer that feels almost liquid against the skin. This combination offers not only luxury but measurable performance benefits confirmed by textile engineers and dermatologists alike.

Feather-light and exceptionally soft — up to 50% softer than cotton, according to Lenzing™ research
Breathable and temperature-regulating — prevents overheating and moisture build-up, essential for comfort in the groin area
Moisture-wicking and quick-dry — absorbs 50% more moisture than cotton and releases it quickly into the air
Shape-retaining knit — maintains fit and elasticity after repeated washes
Non-toxic and hypoallergenic — free from harsh dyes and formaldehyde; suitable for sensitive skin and eczema
Doctor-recommended — ideal for those with ultra-sensitive skin or prone to irritation
Supportive of male fertility — keeps the area cool and dry, avoiding the heat-trapping effects of synthetic fabrics like polyester
Environmentally responsible — made in a carbon-neutral, closed-loop process
