Mens Bottoms - Boxer Brief

"Favorite part is the waistband. Super comfortable with no irritation or bunching. " Rachael P.

Our most wanted. A boxer brief designed to flatter - in bed or out. Compliments like “softest, most comfortable, boxer ever” have been said, as well as one that alluded to our  “sophistication”. It’s also been described as “sexy”. (Well, blush, what can we say?)

P.S.:  Our boxer brief is not only our “hero” product, it’s also one of our most popular gifting items.


  • The first boxer in the market that does away with the traditional elastic waistband for a comfortable and more elevated look
  • Exceptional fit - neither tight and short, or loose and long, just right
  • Ultra soft and breathable fabric
  • Designed for comfort and to perform (flat-lock stitching provides a seamless, more comfortable finish around your assets)

    FABRICATION: 95% Tencel Modal/ 5% Spandex.

    COMFORT GUARANTEE: We believe in comfort. Which is why we'll give you the comfort of knowing if you are not entirely happy with your purchase, we’ll send you your money back.

    Fit is slim fit, good for those who like snug. For a looser fit, go up a size.

    Why Sir Cadian?

    Comfort & Appeal

    Now that you’ve seen Sir Cadian, you might think “Dressing for Bed” is a good idea. And that’s true. After all, Sir Cadian Sleepwear takes men’s favorite bedtime go-to’s and elevates them by creating a better bedtime experience. So cut, style, comfort, wearability, and fit all combine to create a collection of casually inclined, yet coolly refined men’s sleepwear that you will enjoy wearing in bed. And wherever.

    Earth friendly

    Sir Cadian is a reflection of its millennial founders in that they wanted to create something that solved "his" unexciting sleepwear - but it had to be done in an earth-friendly way. Sir Cadian had to be sustainable. This meant sourcing fabrics that were plant-based ✔ Buttons that weren’t plastic ✔ Packaging that was biodegradable ✔ And doing the right thing by making a more planet-conscious product (always and ever in process).

    Your happy SO

    (OK that’s maybe THE reason.)
