Fabric & Care

CUFT® is crafted from 100% TENCEL™ fabric, designed to be both compostable and disposable. We avoid toxic synthetic and polyester blends commonly used in durable industry-standard underwear, resulting in a garment that performs differently and may be less long-lasting.

Follow these guidelines to extend the product's lifespan:

  • Machine wash on cold or delicate mode
  • Air drying is the best option
  • You can tumble dry on delicate mode
  • Do not bleach

When your underwear has run its course, compost the entire garment for safe disposal.

Frequently Asked Questions

What makes CUFT® underwear different?

CUFT® is redefining what clean underwear really means.

While most “clean” brands only focus on part of the garment, every inch of CUFT is made with 100% TENCEL™, a naturally soft, breathable, and biodegradable fabric derived from sustainably sourced wood pulp.

We’ve created a truly non-toxic underwear — from fabric to waistband — that’s completely free of PFAS, microplastics, and harsh dyes or chemicals.

No hidden synthetics. No compromises. Just comfort that’s as safe for your body as it is for the planet.

How is CUFT® underwear compostable?

Most underwear is designed for durability using synthetic, plastic-based materials that never break down. CUFT® takes a different approach prioritizing non-toxic, plant-based materials that are safe for your body and can return to the earth at the end of their life.

CUFT® is made without synthetic fibers, elastane, or traditional plastic-based elastic. Even the waistband is made from a biodegradable TPU designed to break down over time, making the entire garment aligned with our plastic-free mission.

What dyes are used in your underwear?

Our dyes are OEKO-TEX® certified and bluesign® approved, meaning they are tested and verified to be free from harmful substances such as:

  • Azo dyes
  • Heavy metals (lead, cadmium, chromium)
  • Formaldehyde
  • Phthalates

They are safe for sensitive skin and meet strict global safety standards.

What’s so special about TENCEL™?

Our underwear and camisoles are made from 100% TENCEL™, a wood-based, plant-derived fiber known for its breathability and softness. Unlike most underwear, which is made with synthetic materials (aka plastic), CUFT® is designed to be a lower-tox alternative that’s gentle on your body.

TENCEL™ fibers are produced using a closed-loop solvent spinning process. The non-toxic organic solvent is recovered and reused at a rate of over 99%, meaning it doesn’t remain in the final fiber.

Feels good underneath leggings!

Feels like I'm not wearing anything on underneath my leggings, which i've never found underwear like that. When i workout they dont move. love them!

Obsessed!

I wear the thongs under my leggings EVERY time I workout. They are not 'seamless' when you look at them, but you literally cannot see them under your leggings. They are breathable and i just feel good wearing them rather than going commando with my leggings.

New version is AMAZING

I was already in love with CUFT and the way their panties made me feel, but now with this new version I'm obsessed. The new fit is even better and hugs you in all the right ways. I even can wear this thong underneath my tight dresses and the panty lines aren't visible!
I'll be replacing all my toxic thongs with CUFT.

Marathon Approved!!!

I just ran a marathon this weekend and knew the only underwear I would be wearing is my CUFT thong. There is no other undie that I trust to go the distance (literally) in terms of sweat absorption, mobility and comfort. I couldn't even feel my thong during the many miles and an extra plus for the lines not showing under my tight athletic shorts!!

Thank you CUFT for being my marathon buddy :)

So soft

These are sooooo soft. Very thin, which makes them good for hot weather.

extremely comfortable

I've been wearing Cuft's non-toxic underwear for a while now and they're extremely comfortable. The fabric is soft, feels like it's barely there, and unlike a lot of underwear I've tried, they actually stay put and don't ride up. I love that they're made without the toxic chemicals found in a lot of conventional underwear!

Every piece feels incredibly soft on my skin

I love Cuft because every piece feels incredibly soft on my skin and I love knowing it's made with non-toxic materials that support my body and overall well-being.

As a biochemist, I am super strict about the fabrics that touch my body.

As a biochemist, I am super strict about the fabrics that touch my body. CUFT pieces are not only luxuriously soft but also non-toxic and breathable on your most sensitive skin. They easily fit into and elevate my wardrobe!

Non-toxic TENCEL™ underwear and basics

I love that CUFT is making non-toxic TENCEL™ underwear and basics free from synthetic dyes and pesticide residues. It is clear the brand is prioritizing both consumer health and transparency, which are two things I always look for when recommending products and brands to my community.

I am so happy this brand exists

I am so happy this brand exists. My go-to for super soft basics that are healthy for the skin. As a microplastics expert, the first thing I tell people is to wear organic cotton underwear. But there are so few brands really doing it right. It’s such a relief to excitedly point people to CUFT. Will be a longterm supporter!!

CUFT is a very authentic fit for me

I absolutely love the undies and camisoles! They've become staples for me, and are in my go-to non-toxic underwear recommendations. CUFT is a very authentic fit for me.

very breathable and lightweight

Disclosure: I was gifted 2 pairs. The fabric is very lightweight and breathable. I usually wear a M but my measurements put me at a L so I sized up. I don't think you need to size up as the undies feel true-to-size and lyocell is stretchy. My only note is that the gusset is quite short/low and I would love to see it extended a couple inches.

Love these!

It's hard to find great non-toxic underware. These are so comfy and soft! Will definitely buy more!

No greenwashing

As a former cosmetic chemist, I read labels for a living and CUFT is one of the few intimates brands that actually passes my test. No greenwashing just genuinely clean materials against your skin where it matters most while every piece feels so soft on the skin.

Light weight and Intentional

CUFT has become such a beautiful part of my wellbeing rituals. I love how light weight and intentional each garment is. As someone who teaches wellbeing and nervous system regulation, I appreciate brands that encourage sustainability and self-care in a way that feels both elevated and accessible. I’m grateful to support a company that’s creating products with so much heart and purpose. Whether I’m chillin on the couch or wearing them as a first layer I feel comfortable and safe from harmful chemicals.

So soft and breathable

So soft and breathable. You can feel the difference between this underwear and synthetic

Thank you for your feedback! We pride ourselves on ultra soft fabric that is naturally breathable

Breathable!!

I wore my thong this weekend and felt an immediate shift after just one wear. It takes a little time to get used to but that's the point, Cuft is supposed to be changing the way you wear underwear!! The quality and fabric of the underwear was impressive even from just opening the package. It feels breathable to wear while also providing the proper coverage. The packaging it came in was super cute too. I'm excited to re-use them after washing and continue to become accustom to the nontoxic lifestyle!

What a ripoff.
Sorry - just terrible

I hate writing such a negative review. I would not advise anyone to purchase this product. The fabric is thin, lacking any shape or form, like gauze. There is no elasticity whatsoever to hold the garment to your body. The size, XS in my case, is enormous. Unfortunately I opened them before reading the return policy. Each garment was packaged in individual tubes with a sticker. I have broken the sticker and now can't return them. I think the tube is potentially more useful than the underwear.

Thank you for taking the time to share your feedback. We understand that CUFT® may feel different from traditional underwear, especially because our products are intentionally made without elastane, polyester, or other synthetic fibers commonly used for stretch and structure.
Our fabric is lightweight by design and relies on the knit itself for comfort and breathability rather than synthetic elasticity. We know this feel is not for everyone, and we truly appreciate you giving us a try. Regarding sizing, our newer Better for You Underwear™ collection was redesigned to offer more structure and a more traditional fit based on customer feedback. We’re a very small team and genuinely try our best to respond thoughtfully and promptly to every customer who reaches out. We are always happy to make it right with you, just email us!

We truly appreciate your support and feedback as a women-owned business. Every piece of input helps us improve!

Soft fabric

Soft fabric. The fit starts to loosen as you wear it, but for a natural fiber undergarment it’s nice.

Compost

I thought they were comfortable enough. But after only two wears, they started to get holes. Overall, most expensive compost I’ve purchased.

Nice Underwear

feel and that the material is non-toxic!

no notes!

It's hard to find underwear that is truly ONE HUNDRED PERCENT non-toxic! Even my 2nd-fave cotton brand has at least 10% plastic-based materials. Cuft proves even that 10% is not necessary for a perfectly fitting, super comfortable, well-made pair. I love how lightweight they feel. On a mission to replace the whole drawer.
