underU4men represents a culture born from a sport that grew into a passion for fashion and function, locally owned and operated in the Pacific Northwest for over a decade.

Our founder, Steven Lien, is a 4th generation Oregonian who grew up working in the Ski Industry. Later, a unique opportunity took him into a technology career with a Swedish company in IT supply chain. After years of world travel and a desire to return to his love of retail, Steven worked to bring to the U.S. what Europeans have loved for generations; quality men’s fashion underwear. Founded in 2006, underU4men has grown to become the leading independent retailer in the industry.

Our stores have a comfortable, fun, and approachable atmosphere.  Staff can help with fit and function and tell you about our many natural fabrics that have become our specialty.  We invite you to see, touch and experience the softness of Bamboo Rayon, the luxury of Modal derived from the Beechwood tree, or Tencel, the unique fabric from Eucalyptus. With hundreds of amazing brands curated from around the world, you are sure to find your favorite in swimwear, underwear, and gymwear.

We have combined our apparel with the most extensive offering of curated men’s apothecaries, with over 1,000 products from around the world. This in-store department is also available online in its unique store, apothecary4men.com.

When selecting our brands, it’s done with purpose; we prioritize local makers and brands based in the Pacific Northwest, especially those owned by BIPOC, LGBTQ, and Veterans.  Our “Buy with Purpose” has made a difference for several small makers, and we are pleased to expand that offering in 2023

You will truly love exploring the stores. Our expert and passionate staff are uniquely qualified to guide you through our offerings.

We hope to see you soon.

Seattle | Capitol Hill

Our Seattle boutique is inspired by the many intimate apparel shops in Europe; this location is a testament to that heritage.   Located at the North end of Broadway on Capitol Hill, you will discover the historic Loveless building with its “Charles Dickens” charm that brings together several excellent small shops; at the center is underU4men.  You will explore Hugo Boss and Saxx underwear on the shelves of the library room, then walk into the fireplace room to discover designer brands basking in the glow of a real fire.  Our offering is for everyday form and function to that special pair for your Friday night.  We are well known for unique gifts, perfect for a birthday, anniversary, or wedding.  There’s so much more than underwear … our Swim Resort and Gymwear departments are well-stocked year-round with the only offering of Speedo on the Hill.
