“Onsen’s distinct waffle-knit towels are the rare online favorite that actually over deliver on performance.”

“This material is extremely absorbent and super light, which allowed us to dry off more quickly using a towel that never felt heavy, even when wet.”

“I liked [Onsen] so much I bought a second set, and now they’re my go-to towels - I refuse to shower without a clean one at the ready.”

“The Bath Robe design is deep-pocketed and hooded; the fit is oversized and relaxed; the weave is waffly and lightweight.”

Heritage that inspired
a better towel

Inspired by his Japanese heritage and his time spent living and working in Japan, our founder wanted to design a towel that embodies product functionality while elevating the basic routine of bathing into a joyful ritual.

Our mission

Onsen exists to restore the value of overlooked basics through smarter, functional design.

We make basics that are exceptionally useful so you don’t even have to think about them, and can focus on the experiences that make life worth living.

Made of 100% USA Sourced Supima Cotton

Supima Cotton

Crafted of 100% American-grown Supima cotton. Supima’s extra-long fibers are 50% longer than those of other cottons, so they can be spun into yarn that’s up to 45% stronger, too. This means your towel is an investment that has a long, durable life.

Exceptional Strength

Because Supima cotton is up to 45% stronger than other cotton, our towels last longer, so you spend less money over time on better quality products.

About Material

We love these towels - they're super soft, soak up water quickly, and look great. The yellow colour is lovely and brightens up our bathroom.

These towels are wonderful - they're light and luxurious, generously sized, cozy to wrap in... The texture is gorgeous, and they dry quickly. We love them. The hand towels are also lovely.

I've had these towels a few weeks now, and they're still great. The soft waffle texture feels great against my skin. The color hasn't budged. Highly recommend.
