From your little one's first pair to his teenage years — S45 Jeans Co. has been crafting quality denim since 2017. Sizes 16 to 40. Over 200 designs.
S45 Jeans Co. is a dedicated boys' jeans brand founded in 2017. We exist for one reason — to make denim that fits boys properly, lasts long, and looks good doing it.
We are not a fashion brand that happens to make jeans. We are a jeans brand. It is all we do, and we do it with full focus on quality, fit, and comfort for every age and every size.

05Fitted through the thigh, flaring gently from the knee. A classic, smart silhouette that pairs well with all footwear — great for occasions and everyday.
06Since 2017 we have been exclusively focused on boys' jeans. Nine years of singular focus has given us knowledge that generalist brands simply do not have.
Sizes 16 to 40 — each one proportioned for the actual body at that age, not just a resized version of an adult cut.
Over two hundred distinct styles across six fit types — different washes, finishes, and details. There is always something new, and something right for your boy.
We are not a clothing brand that also makes jeans. We are a jeans brand. Denim is our entire focus — the fabric, the fit, the finish.
