The six reasons
6 reasons to switch to 100% TENCEL™.
What is actually in your underwear, what it is doing to your skin, and what changes when you take the plastic out.
Reason 1
It’s 100% pure TENCEL™. No blends, nothing hidden.
Most “clean” or “natural” underwear is still 10 to 30% plastic: elastane, nylon, or polyester blended in. CUFT® is made from 100% TENCEL™, a plant-based fiber, with no synthetic blends. Even our waistband is plant-based, made from biodegradable TPU instead of petroleum plastics. What’s on the label is what’s on your skin.
“Even my 2nd-fave cotton brand has at least 10% plastic-based materials. CUFT proves even that 10% isn’t necessary for a perfectly fitting, super comfortable pair.”McKenzie
Reason 2
Plant-based fiber means no microplastics on your skin.
Synthetic underwear can shed microscopic plastic fibers onto your skin and enter the body through pores or sweat glands. Because TENCEL™ comes from sustainably sourced eucalyptus, there are no plastic fibers to shed. Just soft, plant-based comfort you can feel good about all day.
“Love the very lightweight, natural feel, and that the material is nontoxic.”Emma P.
Reason 3
Naturally breathable and moisture-wicking.
Where cotton absorbs and holds moisture, TENCEL™ wicks it away, so you stay fresh and dry. It’s naturally breathable and antibacterial, designed to support your intimate health and daily comfort, whether you’re at the gym, asleep, or living your life.
“The best underwear! So breathable, my go-to pair for working out and sleeping.”Kayla W.
Barely-there softness that disappears under everything.
CUFT® feels like nothing’s there. Lightweight, soft, and smooth enough to vanish under leggings and tight dresses. No adjusting, no riding up. The kind of comfort you forget you’re wearing.
“Feels like I’m not wearing anything underneath my leggings. When I work out they don’t move. Love them!”Lauren
Reason 5
The switch doesn’t stop at your underwear.
Your feminine care matters just as much as what you wear. The same brand behind compostable, certified-clean underwear makes feminine care to match, from wash to daily essentials, free from the fragrances and harsh ingredients hiding in most products, and gentle enough for the most sensitive skin. One nontoxic routine you never have to second-guess.
“I love that this is nontoxic, and I can put it all over my body.”Verified buyer
Reason 6
Every 3 pairs you buy gives 1 to a woman who needs it.
Underwear is one of the most-requested items at women’s shelters. For every three pairs sold, CUFT® donates one to a woman in need, so getting yourself something better also does some good.

Our story
Built by a mother and daughter who wanted better.
CUFT® began with a mother and daughter who couldn’t find underwear they trusted against their own skin, so they made it themselves. Today it’s women-owned and GOTS Certified, built on health and transparency.

FAQ
Good questions, answered.
Why is the price higher than regular underwear?
100% TENCEL™, third-party certified, compostable, and every third pair gives back. You’re paying for what isn’t in it as much as what is.
What’s in the bundle, and is the feminine wash clean too?
Every bundle pairs soft 100% TENCEL™ underwear with our plant-based feminine wash. The Complete Nontoxic Routine also adds our Better for You Cami™. The wash is made to the same clean, nontoxic standard as everything we make, and is gentle enough for the most sensitive skin.
How do I find my size, and does it run small?
Check the size guide on each product page for measurements by style. If you’re between sizes or unsure, our first-fit guarantee has you covered, so you can order with confidence.
How long does a pair last?
With gentle care, a pair holds up through regular wear and washing. Because the fabric is lightweight and plant-based, we recommend washing cold and air drying to keep it feeling its best.
How do I wash it, and how do I compost it?
Machine wash cold on a gentle cycle and air dry. Because it’s made from plant-based TENCEL™, a worn-out pair can be composted at the end of its life rather than sent to landfill.
What if the fit isn’t right?
Our first-fit guarantee has you covered. If the fit isn’t right, we’ll work with you to find the perfect size, and eligible first-time customers can receive a replacement or store credit, because your first pair should fit just right.
Is it really 100% TENCEL™?
Yes. The body of the garment is 100% TENCEL™, OEKO-TEX® certified and bluesign® approved.
A nontoxic routine that’s better for you, and gives back.
Make the switch today, backed by free shipping and our first-fit guarantee.
