Product Features

Ultra-thin 55g/m² fabric

The significantly lighter 55g/m² fabric feels like wearing nothing at all. Air passes through easily, preventing the fabric from sticking to your skin. Despite its lightness, the high-density knit ensures strength, making it durable enough for daily washing.

Contact Cooling Treatment

The contact cooling treatment quickly dissipates heat the moment it touches your skin. The "cool" feeling when you put them on in the morning starts your day comfortably. This is a must-try for anyone who sweats easily on trains, in the office, or during their commute.

7A Antibacterial for Zero Odor Worries

Industry-leading 7A level antibacterial treatment. It suppresses the growth of odor-causing bacteria even after long hours of wear, maintaining a fresh feeling that lasts until evening. Perfect for business trips or after the gym when you're concerned about odor.

Gusset-free Design × Flat Seams

By deliberately omitting the cotton gusset, we've achieved a seamless, smooth feel akin to silk. The seams are also flat-processed, reducing chafing and bulkiness in delicate areas. The design ensures no visible lines under skinny pants.

2cm Wide Waistband

The 2cm wide elastic waistband ensures no rolling up whether you're sitting or standing. It holds securely without constricting your abdomen. Stay stress-free throughout an active day.

Frequently Asked Questions

Q. Is it really cool?
A. Yes. The contact cooling treatment provides an immediate cool sensation when worn. The ultra-thin 55g/m² fabric enhances breathability, reducing stuffiness even after long periods, and keeping you dry even when you sweat.

Q. Does the antibacterial property last after washing?
A. The 7A antibacterial treatment is processed at the fiber level, so its performance is designed to be resistant to degradation from normal washing. However, chlorine bleach and high dryer temperatures can reduce performance, so we recommend washing in a net and air drying in the shade.

Q. I'm concerned about durability since it's thin.
A. While it is thin at 55g/m², its high-density knit ensures strength. It has durability comparable to standard boxer briefs, so you can use it with confidence in your daily rotation.

Q. Can I choose the colors for the set of 3?
A. We offer sets of 3 in a single color: "Cool Black 3-pack," "Soda Blue 3-pack," and "Mint Green 3-pack." Please choose your preferred color.
