Picture the moment you slip into a freshly laundered pajama set — that first contact with skin, the quiet exhale that follows. The fabric you're wearing shapes that entire experience. Between pima cotton vs. modal, each offers a different kind of softness. Eberjey describes the TENCEL™ Modal in its Gisele TENCEL™ Modal Long PJ Set as silky-smooth and breathable, and its Organic Pima Cotton as gentle and breathable. Which one belongs in your nightly ritual depends on how you sleep, what your skin craves, and the version of softness you want to come home to.
What Is Pima Cotton, and Why Does It Feel So Different From Regular Cotton?
Not all cotton is created equal. Pima cotton is a variety of extra-long staple (ELS) cotton. Supima®, the trademark for 100% extra-long staple cotton grown in the USA, says its extra-long staple fiber makes it inherently softer and helps it resist pilling, breaking and tearing.
Supima cotton is grown only in the USA, in the American West and Southwest. Pima cotton is also grown in Peru: Eberjey's Organic Pima Cotton PJ sets are made from 100% Organic Peruvian Pima Cotton.
What Makes Pima Cotton Feel Different on Skin?
Here is what that longer staple means in practice:
- Softness: Supima says its extra-long staple fiber makes it inherently softer and more luxurious.
- Breathability: Eberjey describes its Organic Pima Cotton as gentle and breathable.
- Durability: Supima says its longer fibers resist pilling, breaking and tearing and keep their form.
What Is Modal Fabric, and How Is It Made?
Modal is a regenerated cellulosic fabric made from wood pulp; TENCEL™ Modal uses wood from responsibly managed forests. The Austrian fiber company Lenzing AG converts that pulp into a soft, pliable fiber using highly resource-efficient technology with high recovery rates of chemicals.
TENCEL™ Modal is the fiber at the heart of Eberjey's signature sleepwear. 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.
Which Fabric Is Actually Softer: Pima Cotton or Modal?
Which feels softer is personal, because the two fabrics are soft in different ways.
Here is how the two fabrics break down across the dimensions that matter most for sleepwear:
| Quality | Pima Cotton | Modal (TENCEL™) |
|---|---|---|
| Fiber | Natural extra-long staple cotton | Regenerated cellulosic fiber from wood pulp, made by Lenzing |
| Softness | Supima says its extra-long staple fiber makes it inherently softer | Lenzing says the fiber cross-section favors fabric softness |
| Through the wash | Supima says longer fibers resist pilling and keep their form | Lenzing says the fibers withstand repeated washing and drying |
| Moisture | Breathable, per Eberjey's Organic Pima Cotton | Absorbs and releases moisture, supporting a drier microclimate on the skin (Lenzing) |
| Eberjey care | Machine wash cold, gentle cycle, tumble dry low | Machine wash cold, gentle cycle, tumble dry low |
| Sourcing | Supima is grown only in the USA; organic options available | Wood from certified or controlled sources; resource-efficient production |
Eberjey's Gisele TENCEL™ Modal Long PJ Set has earned more than 1,400 five-star reviews. It is soft enough to feel like a daily luxury, considered enough to sleep in every night.
Which Fabric Is Gentler on Sensitive Skin?
If you have sensitive skin, look for a smooth fabric and independent testing. Eberjey describes the TENCEL™ Modal in its Gisele TENCEL™ Modal Long PJ Set as silky-smooth, with a top and pant that move with you all night, and its Organic Pima Cotton as gentle and breathable. If you have a skin condition, check with your dermatologist.
If you prefer organic fibers, look for GOTS (Global Organic Textile Standard) certified pima cotton.
Which Is More Sustainable: Pima Cotton or Modal?
Sustainability is genuinely nuanced here. Both fabrics carry real credentials — and real tradeoffs.
Pima cotton: Supima says its extra-long staple fibers resist pilling, breaking and tearing, and a garment that lasts is one you replace less often. Certified organic cotton is grown without synthetic pesticides and fertilizers, apart from the limited list allowed under organic rules. For more on choosing responsibly, see our guide to sustainable sleepwear.
Modal (TENCEL™): Lenzing produces TENCEL™ Modal with highly resource-efficient technology and reports carbon emissions and water consumption at least 50% lower than generic modal fibers. The wood comes from FSC® or PEFC certified or controlled sources.
That transparency is part of TENCEL™ Modal's appeal.
How Do Pima Cotton and Modal Compare for Everyday Care?
Both fabrics are easy to care for, and Eberjey's care labels for the two are nearly identical.
Eberjey Organic Pima Cotton care:
- Turn inside out and machine wash cold with like colors, gentle cycle
- Non-chlorine bleach only, when needed
- Remove promptly and tumble dry low; warm iron as needed
Eberjey Gisele TENCEL™ Modal care:
- Turn inside out and machine wash cold with like colors, gentle cycle
- Non-chlorine bleach only, when needed
- Tumble dry low; warm iron if necessary
In practice, the routine is the same for both: cold water, a gentle cycle and a low dryer setting. Lenzing notes that TENCEL™ Modal fibers are made to withstand repeated washing and drying cycles.
Which Fabric Works Better Across Every Season?
Both fabrics can be worn year-round; the cut of the set matters as much as the fiber.
Eberjey describes its Gisele TENCEL™ Modal as a temperature-regulating fabric, and many of its Gisele styles come in long sets for cooler nights and short sets for warmer ones.
For warm nights, our guide to the best summer pajamas covers lightweight fabrics and cuts, including cotton and modal.
For a single investment piece that works across every season, Eberjey's Gisele collection in TENCEL™ Modal earns its enduring reputation. If warm-weather sleeping is your priority, the Gisele TENCEL™ Modal Shortie Short PJ Set, which Eberjey describes as perfect for hot sleepers and warm nights, comes in the same TENCEL™ Modal.
What to Look for When Buying Pajamas in Either Fabric
Whether you choose pima cotton or modal, quality varies enormously within each category. Here is what to look for:
For Pima Cotton Pajamas:
- Certification: Supima® marks 100% extra-long staple cotton grown in the USA; for organic cotton, look for GOTS certification
- Weight: choose a fabric with enough substance to drape well without feeling heavy
For Modal Pajamas:
- Fiber source: TENCEL™ Modal is a branded fiber made by Lenzing AG, while generic "modal" doesn't tell you who made the fiber
- Certifications: OEKO-TEX Standard 100 is the minimum; look for it on the label
- Blend ratio: Check the fiber content on the label; Eberjey's Gisele TENCEL™ Modal Long PJ Set is 95% LENZING TENCEL™ Modal and 5% elastane
Eberjey's Gisele TENCEL™ Modal Long PJ Set checks these boxes: 95% LENZING TENCEL™ Modal with 5% elastane, verified by OEKO-TEX® Standard 100.
Pima Cotton vs. Modal: Finding Your Softer Side
The softest pajamas are the ones you actually reach for — night after night, season after season. Modal, with its silky drape, temperature-regulating feel, and long-lasting buttery-soft hand-feel, suits those who want their nightly ritual to feel like a quiet luxury. Pima cotton, crisp and breathable and enduring in its own right, is the choice for anyone drawn to the clean, considered feeling of classic cotton. Neither is wrong. Both are a genuine step toward more effortless, more restful inside life — the kind that begins the moment you get dressed for bed.
