Let’s name the problem properly, because the towel industry never does. It isn’t softness — every towel is soft when it’s new. It’s the musty smell: the damp terry cloth that never fully dries between showers and starts announcing itself by Wednesday. Onsen was built on that exact complaint. Founded on Kickstarter in 2017 by Shane Monson, who drew on Japanese bathhouse tradition, it makes a $59 waffle-weave Supima cotton towel engineered to dry fast and stay fresh rather than to feel like a spa robe. That’s a real distinction, and it decides whether this towel is brilliant or a waste of money for you. This Onsen waffle towel review sorts out which.
Why Trust This Review
This is independent research — nobody pays for verdicts at Coco n Deals. For this article I went through a four-year owner’s long-term account (a towel they bought themselves, not a freebie), Thingtesting’s full spread of owner reviews including the critical ones, the brand’s certification records, and its published specs. My full archive is in the reviews section.
What Is the Onsen Waffle Towel?
The Onsen Supima cotton towel is the brand’s flagship: a waffle-weave bath towel measuring 38 x 67 inches — generously oversized against a standard 27 x 52 — and weighing 22.2 ounces, considerably lighter than a typical 30-to-40-ounce terry towel. The weave is the whole engineering story: a honeycomb texture whose pockets trap moisture and multiply surface area, so the towel absorbs well and then dries fast enough that it never sits damp long enough to go musty. The material claims hold up unusually well to scrutiny — Supima is a licensed trademark, not a marketing word, granted only for verified American-grown extra-long-staple Pima cotton, and Onsen also carries OEKO-TEX Standard 100 certification (tested against 350 harmful chemicals). One honest note: the cotton is American, but the weaving and finishing happen in China. Onsen has since added Sculpted Terry and Plush lines for traditionalists, plus hand towels ($20–$30), face towels ($15–$20), and bath sheets; the company was acquired by Pattern Brands in 2022. The name means “hot spring” in Japanese.
What the Onsen Towel Gets Right
- It actually solves the smell: a reviewer four-plus years into daily use reports it has never, ever stunk — the fast-drying weave never gives mustiness a window.
- Absorbency that surprises people: owners consistently say it soaks up more than their terry towels despite being visibly thinner — the waffle pockets are doing real work.
- Material claims with paperwork: licensed Supima (a certification you can’t fake, unlike “Egyptian cotton”) plus OEKO-TEX Standard 100 — rare honesty in the towel aisle.
- Genuinely oversized: 38 x 67 inches against a standard towel’s 27 x 52 — more towel, less weight, which is the whole Japanese design argument.
- It holds up: multi-year owners report the cotton doesn’t thin out — the durability that makes $59 amortize instead of sting.

What Real Owners Say — The Texture Divide
The four-year account is the most convincing evidence I found: bought with their own money in 2018 specifically to beat the musty-terry problem, and four-plus years later it has never once smelled — while also proving more absorbent than terry and holding up without thinning. Thingtesting’s owners echo it: bigger than their terry towels, amazingly absorbent, dries fast, high-quality cotton you can feel, and a tight weave that catches drips. Several call it worth the money because the towels last and don’t thin out.
And then there’s the texture divide, which is the honest heart of this review. Onsen towels are thin and crisp, not plush — and owners split hard on that. Some describe the waffle as mildly abrasive, one memorably comparing it to drying off with sackcloth; another found it “sort of rough” and keeps better towels in rotation for daily use. Several bought bath sheets and found the oversized version felt like wrapping an actual bedsheet around themselves, recommending the standard size instead. The waffle also snags on jewelry and jagged nails, and it hangs less neatly on a rod than terry. Price gets flagged constantly at $59 (though sales are frequent), and one detailed 2026 review reports customer service has serious problems if an order goes wrong. My read is clean: buy this if your enemy is mustiness; don’t if your dream is a plush spa wrap. It’s a different product solving a different problem — the same clear-eyed trade I applied to design-first drinkware in the
Corkcicle tumbler review earlier in this collection.
The Social Media Story
Onsen came up through Kickstarter and never lost that founder-story register: Shane Monson’s Japanese heritage, the onsen bathhouse tradition, the waffle weave as a design philosophy rather than a texture. Its social presence lives in the minimalist-home and Japandi corners of Instagram, where the crisp folded stack photographs beautifully, and in the guest-bathroom aesthetic content that keeps it in gift guides. Since the Pattern Brands acquisition it’s been reaching a broader home audience, and the towel remains a fixture of “things that fixed a problem I’d given up on” posts — which is exactly the right niche for it.
My Verdict: Is the Onsen Towel Worth It?
Yes — for one specific person. This Onsen waffle towel review comes down to a single honest question: does your towel smell? If yes, this $59 towel solves it, permanently, with four-year proof and real certifications behind the material. If your complaint is that towels aren’t soft enough, this is the wrong purchase and you’ll be annoyed — buy the Plush line or stay with terry. Start with a hand towel to test the texture, buy on a newsletter discount, and skip the oversized bath sheet unless you like being wrapped in a bedsheet. Odor resistance: 5/5. Absorbency: 4.5/5. Plushness: 2/5. Value on sale: 4/5.
FAQs
Do Onsen towels really not smell?
That’s their whole design, and the long-term evidence backs it: a reviewer four-plus years into daily use reports zero mustiness. The waffle weave dries fast enough that the towel never sits damp long enough to develop odor.
Is the Onsen Supima cotton towel soft?
It’s crisp and textured, not plush — some owners find it mildly abrasive at first, most get used to it quickly. If softness is your priority, Onsen’s Plush or Sculpted Terry lines exist precisely for you.
Is Supima cotton a real certification?
Yes — it’s a licensed trademark granted only for verified American-grown extra-long-staple Pima cotton, unlike unregulated “Egyptian cotton” labeling. Onsen also carries OEKO-TEX Standard 100, tested against 350 harmful chemicals.
Are Onsen towels worth $59?
If mustiness is your problem, yes — they last years without thinning, and discounts through the newsletter and regular sales soften the price. If you want plushness, no towel at any price will fix that mismatch.
