Silky Soft Pyjamas

Say Goodbye to Chafing.

Finer than silk, twice as soft as cotton.

Made with the finest TENCEL™ fibers, our underwear feels silky-smooth with a gentle, second-skin stretch that moves with you. No friction. No irritation. Just effortless comfort—every single day.

Sweat-Proof. Odor-Free.

4x more breathable than cotton.

Tani's fabric wicks away sweat instantly and prevents odor-causing bacteria before it starts. Stay dry, fresh, and confident—no dampness, no smells, no distractions.

Never Adjust Again.

A perfect balance of stretch, support, and softness.

Most underwear rides up, bunches, or shifts, forcing you to constantly pull it back down. We solve this with a high-quality elastane blend for flexible support, precision-stitched leg openings for the perfect amount of stretch, and a no-roll elastic waistband that stays put. 

Built to Last.

Long-lasting softness and support.

Underwear takes a beating—frequent washes, daily wear. Our special blend TENCEL™ Modal keeps its softness and shape 90% longer than cotton, so you get lasting comfort without sagging or thinning.

Lower Impact

Made with TENCEL™ derived from sustainably sourced beechwood in a closed-loop process that recycles 95% of resources and uses 20x less water than conventional fibers. Luxurious comfort, lower impact.

What is "Underdog" ?

a play on words...Combining the specialty of Tani - UNDERwear, with our love of animals, especially DOGs. In English, the word "underdog" is often referred to the weaker party, the less fortunate in the society.

everyone loves an underdog...is the charitable arm of Tani Japan. Proceeds from the sale of this collection will go to fund projects that raise awareness and offer financial help to the underprivileged.

Project Partner
Dog Shelter, Tokyo, Japan

Sales proceeds (after deducting production cost) from the Underdog project in Japan will go to fund Tokyo-based Dog Shelter <dogshelter.jp>

Dog Shelter was founded by Mrs Mina Kataoka in 2006. The small organization is run by volunteers only. Every dog they take in undergoes thorough medical check and home fostering before being matched to their new permanent home. Every prospective dog owner and their home are also vetted by the team. 

Dog Shelter has re-homed over 900 dogs in the Kanto and Kansai area. Only 2 dogs have ever been returned to Dog Shelter following their formal adoption, testament to Mrs Kataoka and her team's serious and thorough work.
