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.)
