Bold Designs, Athlete Collabs & Everyday Comfort

SD Underwear began in 2008 when brothers Curt and Ryan Flaitz decided to reinvent everyday basics. Originally launched under the name Pant Saggin Dezign, the brand was inspired by streetwear culture and a desire to make underwear just as exciting as the rest of an outfit.

From its early days, PSD stood out with bold prints, creative designs, and collaborations with athletes, artists, and cultural icons. The brand quickly gained recognition in the United States, where professional athletes started wearing PSD both on and off the court.

Over the years, PSD expanded its range to include men’s boxers, women’s sports underwear, and lifestyle essentials, all crafted from high-quality fabrics designed for comfort and durability. Today, PSD is sold worldwide and is known as a leading underwear brand that blends style, performance, and individuality.

Bold & Creative Designs by PSD Underwear

One of the things that makes PSD Underwear stand out is its unique and eye-catching designs. Instead of plain basics, PSD turns underwear into a canvas for bold prints, vibrant colors, and playful graphics. From comic-inspired patterns and pop culture references to sleek geometric styles, every design is created to bring personality into everyday essentials.

The brand often collaborates with athletes, musicians, and artists, adding fresh energy and limited-edition prints to the collections. These designs allow you to express yourself in a fun and stylish way, whether you’re wearing them under gym gear, casual outfits, or simply at home.

With PSD, underwear isn’t just about comfort — it’s about making a statement.

According to Happy Socks themselves, they make great socks. And we can only agree! They design eye-catching patterns and details while focusing on finding more durable materials, as new products constantly strive to outperform the previous ones. The constant search for materials that make their socks both softer and stronger makes Happy Socks a brand that stands the test of time in style.
