Tani uses the World's Best Fabrics


All our fabrics, materials and finishes are carefully considered with no more than two things in mind: Is it more comfortable? Will it out-perform to create the best mens underwear? And then we travel.

Over the years, we’ve been around the world researching remarkable new fabrics and innovative knitting and finishing techniques. And we source only the highest grade of each fabric. We don’t cut corners by using knock-offs or “just like the real thing” fabrics. The result is underwear, loungewear and thermal clothing that we can comfortably guarantee is like nothing you’ve ever put on. We create the world’s best mens underwear.

Micro Modal AirIt takes Europe’s most sophisticated fine-gauge knitting machines to produce this extraordinary fabric. It’s thinner than silk. It’s softer than silk. It’s far more durable than silk. And Tani is the only men’s underwear that has it. Ok so it’s soft and wonderful, but it’s also highly functional, as the fabric’s natural properties wick moisture away from your skin to help keep you cool and dry. And even after repeated washing, the fabric retains its shape and color. And, speaking of natural, it’s made entirely from sustainable natural resources and in an environmentally friendly manner. Oh, and it’s also biodegradable.


TencelThis is an extremely fine fabric created in Europe for high comfort and high performance. Despite its fine texture and soft hand, this fabric is a hard worker, able to wick away 50% more moisture than cotton. It’s naturally hygienic and inhibits bacterial growth. Our Micro Tencel® is derived entirely from Eucalyptus, sourced from sustainable Austrian forests, and finished through a highly eco-friendly process. Tani underwear made with Micro Tencel® is so soft, it can be worn comfortably on the most sensitive skin.


CuproCupro® is derived from cotton, but has a denser and more uniform weave than cotton making it far softer to the touch. And this ultra smoothness allows it to drape and retain its shape naturally. Additionally, the fine micro knit allows for faster absorption and natural wicking of moisture than even the finest cotton. And if that wasn’t not enough, Cupro® is also hypoallergenic and antistatic.


Swiss CottonThere’s cotton and then there’s Swiss Cotton™. The difference is that 97% of the cotton produced worldwide doesn’t make the grade. The difference is a soft and supple cotton that feels like luxury on your skin. It is exclusively woven on special knitting machines in Switzerland from the highest grade, extra long staple cotton from the U.S. and Egypt. Compared to Swiss Cotton™, your typical cotton underwear is essentially sandpaper.


ROICAWith the highest stretch and shape retention of any raw textile, Roica™ is, essentially, a spandex of a higher order. Acclaimed for its high performance, easy care and durability, Roica™ performs particularly well when woven with the specialty fabrics of our collections, increasing both comfort and appearance. Roica™ CF combines the performance and quality of Roica™ with effective ionic absorption of odor-causing substances from perspiration, resulting in the most effective odor control fabric on the market.


SuperfineIn the fabric world, Superfine® is a rock star. Essentially, Superfine refers to an extremely high density and fineness of a woven fabric. At the highest and best levels, it is capable of being spun by only a handful of mills worldwide. And only the very finest and smoothest yarns can be used. Fabrics knitted on these Superfine® machines produce a superior quality fabric with a finish that is so smooth, it is literally impossible to see a knit of the fabric with your eyes. It is the absolute pinnacle of softness, durability and comfort in fabric.
