Sleeperbear is a Los-Angeles based athleisure shorts brand started in 2019. Inspired by loose-fitting boxing attire combined with colorful California energy, SleeperBear has built a fashion house focused on everyday shorts for modern movers and shakers seeking comfortable style that showcases their uniqueness. SleeperBear designs are thoughtfully sourced and created from the highest-quality fabrications and materials in the USA.


If you're tired of wearing shorts that hug your hips too tightly, or squeeze your waist, or hang down past your knees, or are just boring blue, it's high time you discover the most comfortable pair of shorts you'll ever own. SleeperBear shorts are made with premium performance fabric and a loose-in-all-the-right places (but not too loose!) fit. We set out to create shorts that were cut for real bodies; shorts that have personality; shorts we could confidently wear in any space. We started from scratch, and ended with shorts our customers never want to take off!


Everything about our shorts is one of a kind. Our cut was crafted and refined by a couture Philly-based designer with extreme attention to detail. Our fabric is custom artist-designed (we partner with all sorts of artists to create entirely original prints!) and printed in Durham, North Carolina and Los Angeles, California. Our hand-illustrated patches and embroidery are printed in Denver, Colorado. And each pair of shorts is cut and sewn in Denver, Colorado by a woman-led production team.
