Premium underwear brand Shinesty is keeping the boys cool with a new line of men’s undergarments made with brrr° cooling fabric.

Shinesty’s new line of cooling boxers are made with brrr° cooling fabric, which has natural cooling minerals, active wicking, and rapid drying to draw heat and moisture away from the skin all day long.

The underwear have a 6-inch inseam and 4-way stretch for superior freedom of movement, while flat stitching prevents skin irritation. Plus they’re lightweight and breathable thanks to the “Triple Chill Effect” from brrr° cooling fabric technology.

Boulder, Colorado-based Shinesty was founded by three friends who wanted to bring an irreverent party vibe and creative themes to the undergarment and apparel industry through an anything-but-subtle approach to branding and marketing.

Shinesty has since become known for its elevated designs, superior materials like brrr° cooling fabric, and premium offerings like a build-your-own pack where you can mix and match styles and prints.

They also offer subscription boxes for men, women, and couples, as well as T-shirts, swimsuits, adult onesies, overall-style pajamaralls, robes, novelty holiday sweaters, and other apparel items.
