Modal vs. Cotton: Which Fabric Is Better for Sleepwear?

Posted by Ashley Martins on July 15, 2026

Picture the moment you finally pull on your pajamas at the end of a long day — that exhale, that settling in. The fabric you reach for matters more than you might think. Modal and cotton are both natural-origin fabrics beloved for their softness and breathability, but they feel and perform very differently against your skin. Modal has a lot to offer: it has a buttery soft hand, drapes easily and is made to withstand repeated washing. That said, the right fabric is a personal one, and both have genuine strengths worth understanding before you choose.

What Exactly Is Modal Fabric?

Modal is a regenerated cellulosic fiber made from wood pulp. TENCEL™ Modal uses wood from responsibly managed forests, from FSC® or PEFC certified or controlled sources. Lenzing produces it with highly resource-efficient technology and high recovery rates of chemicals.

TENCEL™ Modal is made by Lenzing AG, an Austrian fiber company.

Eberjey's signature fabric is TENCEL™ Modal, and it forms the foundation of our best-selling Gisele pajamas; the Gisele TENCEL™ Modal Long PJ Set alone has earned more than 1,400 five-star reviews.

What Is Cotton, and Why Has It Long Been the Sleepwear Standard?

Cotton is a natural cellulosic fiber harvested from the seed pods of the cotton plant. It has been used in clothing for millennia and remains one of the world's most familiar textile fibers. For sleepwear, cotton's appeal has long rested on three pillars: breathability, familiarity, and ease of care.

The Different Types of Cotton Matter

Not all cotton sleepwear is created equal. Standard cotton (often labeled simply as "100% cotton") varies widely in feel. Higher-quality options include:

Pima cotton — grown primarily in the American Southwest and Peru, featuring extra-long staple fibers that produce a noticeably softer, smoother hand.

Organic cotton — grown without synthetic pesticides and fertilizers, apart from a limited list allowed under organic rules.

Eberjey's Organic Pima Cotton PJ sets, made from 100% organic Peruvian Pima cotton, are a natural-fiber option that Eberjey describes as gentle and breathable.

What to Check With Cotton

Cotton is very absorbent: Cotton Incorporated notes it can absorb up to 27 times its own weight in water. Quality varies widely across standard cotton, so check the fiber type and the care label before you buy.

How Modal and Cotton Compare on Softness

Both can be very soft; for a closer look at modal against premium long-staple cottons, see our comparison. Lenzing notes that TENCEL™ Modal's fiber cross-section favors fabric softness.

TENCEL™ Modal fibers are made to withstand repeated washing and drying cycles. This enduring softness is why TENCEL™ Modal is at the heart of Eberjey's signature Gisele PJ Set: it is made to stay soft wash after wash.

Breathability and Temperature Regulation: Which Fabric Keeps You Comfortable All Night?

Both fabrics are breathable, and they handle moisture in their own ways.

Cotton is very absorbent, and Eberjey describes its Organic Pima Cotton as gentle and breathable.

Lenzing says the structure of TENCEL™ Modal fibers allows the absorption and release of moisture, supporting a drier microclimate on the skin and increasing thermal comfort. Eberjey describes its Gisele TENCEL™ Modal as a breathable, temperature-regulating fabric.

The Sleep Foundation suggests approximately 65°F as the best room temperature for sleep.

The Case for Modal With Sensitive Skin

If you have sensitive skin, a smooth fabric and independent testing are both worth looking for. Eberjey describes the TENCEL™ Modal in its Gisele TENCEL™ Modal Long PJ Set as silky-smooth.

Eberjey's Gisele TENCEL™ Modal Long PJ Set is verified by OEKO-TEX® Standard 100, meaning it's dyed with safe and non-toxic dyes, the kind of assurance that matters when fabric touches your skin all night, every night.

With cotton, independent certification is just as worth looking for. Organic cotton certifications like GOTS (Global Organic Textile Standard) address this, covering organic fibers and chemical inputs through the supply chain.

Durability and Care: Which Fabric Lasts?

Washing and Drying
Follow the care label for both fabrics: Eberjey's Gisele TENCEL™ Modal and Organic Pima Cotton pajamas are both machine washed cold and tumble dried low.

Pilling
Both fabrics can pill, particularly in areas of repeated friction (waistbands, underarms, inner thighs).

Wash Cycles
TENCEL™ Modal fibers are made to withstand repeated washing and drying cycles.

Care Instructions
Modal is easy to care for and Eberjey recommends turning it inside out, machine washing cold on gentle with like colors, and tumble drying low. Most Eberjey TENCEL™ Modal pieces are machine washable, making them practical for everyday use.

Is Modal a More Sustainable Choice Than Cotton?

Conventional cotton farming can use synthetic pesticides and fertilizers that certified organic cotton largely avoids.

TENCEL™ Modal is made with resource efficiency in mind. Lenzing's TENCEL™ Modal is made from wood from FSC® or PEFC certified or controlled sources, using highly resource-efficient technology with high recovery rates of chemicals. Lenzing reports that TENCEL™ Modal's carbon emissions and water consumption are at least 50% lower than those of generic modal fibers.

Modal is a semi-synthetic fiber — it requires chemical processing that cotton in its simplest form does not. Organic cotton, grown without synthetic pesticides and fertilizers apart from a limited approved list, is another considered option. For many shoppers, the certifications and transparency behind TENCEL™ Modal make it an easy choice.

So Which Should You Choose for Sleepwear?

The honest answer is that it depends on your priorities — and both are worth considering.

Choose modal if you:

Tend to run warm at night

Have sensitive skin and want a smooth, gentle fabric

Want softness that lasts wash after wash

Care about environmental impact of production

Want a fabric that drapes and moves beautifully

Choose cotton if you:

Prefer a 100% natural, minimally processed fiber

Like the familiar weight and texture of classic cotton

Are choosing premium long-staple cotton (Pima, Egyptian) rather than standard cotton

The best sleepwear is the kind that makes you look forward to the end of the day — fabric that feels like a small, considered luxury you give yourself every night. For us, TENCEL™ Modal's combination of buttery-soft hand feel, temperature-regulating breathability, skin-kind smoothness, and enduring softness makes it the fabric worth choosing. It is not a coincidence that Eberjey's Gisele PJ Set — crafted from TENCEL™ Modal in a relaxed, thoughtfully tailored cut — is the PJ that started it all and our best-selling women's pajamas. When something feels genuinely, wash-after-wash wonderful, you feel it every single morning when you wake up.
