Is modal fabric good for both summer and winter?

Yes. Modal's strength is temperature regulation: it breathes and wicks moisture in summer, and in winter it avoids the damp-then-cold cycle that makes cotton uncomfortable.

How do I care for TENCEL Modal sleepwear?

Cold gentle machine wash, no bleach, skip fabric softener, and line dry in shade. It naturally resists wrinkles so ironing is rarely needed.

TENCEL™ Modal vs Cotton vs Bamboo Pyjamas: Which Fabric Is Best?

Q: Is TENCEL Modal the same as modal?

All TENCEL Modal is modal, but not all modal is TENCEL. TENCEL is Lenzing's certified fibre with traceable beechwood sourcing and closed-loop production, while generic modal can come from any producer.

Q: Are 100% cotton pyjamas good for night sweats?

Cotton breathes well but dries slowly, so once you have sweated into it you stay damp and then get cold. For drenching night sweats, a faster-drying fibre like modal is more comfortable.

If you're comparing pyjama fabrics, you've probably narrowed it to three: cotton (the familiar default), bamboo (the one everyone's marketing), and TENCEL™ Modal (the one premium sleep brands quietly build around). Here's an honest comparison, including where each one genuinely wins, plus what to know about 100% cotton, organic cotton, silk and linen.

At a glance

	TENCEL™ Modal	Cotton	Bamboo (viscose)
Softness & feel	Exceptionally smooth, silky drape; stays soft wash after wash	Soft but varies hugely with quality; can pill and roughen	Very soft initially; quality varies widely between brands
Moisture	Absorbs more than cotton and releases it quickly	Absorbs well but dries slowly — stays damp against skin	Wicks well, though performance varies with processing
Temperature	Breathable, cool to the touch; suits hot sleepers	Breathable when dry; loses insulation when damp	Breathable and cooling
Sensitive skin	Ultra-smooth fibre surface, low friction; hypoallergenic	Good if high quality; rougher weaves can irritate	Generally gentle, but chemical processing varies by maker
Durability	High — resists pilling, holds shape and colour	Moderate — breaks down and thins over time	Lower — prone to pilling, shrinking and losing shape
Sustainability	Beechwood pulp, closed-loop processing, certified sourcing	Natural but water- and pesticide-intensive (unless organic)	Fast-growing plant, but most is chemically processed viscose

Indicative comparison based on typical fibre performance — individual fabrics vary with weave and quality.

The moisture question is the one that matters

Most fabric comparisons obsess over softness, but for actual sleep quality, moisture behaviour is the deciding factor. Everyone sweats at night — hot sleepers and anyone experiencing night sweats, considerably more. Cotton's weakness isn't absorption, it's release: it soaks up sweat and then holds it, so you spend the rest of the night in a damp layer that turns cold. Modal absorbs moisture even more readily than cotton but releases it quickly, keeping the fabric — and you — drier.

Bamboo pyjamas: the asterisk on the label

Bamboo has brilliant marketing: fast-growing, natural, eco-friendly. What the labels often don't say is that most 'bamboo' fabric is bamboo viscose — the plant is dissolved in chemical solvents and regenerated into fibre, and the process (and its environmental controls) varies enormously between manufacturers. The fabric itself is genuinely soft and cool, but quality and consistency are a lottery, and it tends to pill and lose shape faster than modal. We dug into the green claims in is bamboo fabric as green as it sounds?

TENCEL™ Modal is made by a similar regeneration principle but under the Lenzing TENCEL™ brand, which means one certified producer, closed-loop chemical recovery, traceable beechwood sourcing, and consistent fibre quality — the accountability that generic bamboo lacks.

Rule of thumb: if a fabric only says 'bamboo', you don't know what you're getting. If it says TENCEL™, you do — it's a trademark with a single certified source, not a category.

What about 100% cotton and organic cotton?

100% cotton pyjamas are the safe default for good reason: breathable, familiar, easy to wash and widely available. Their limit is the one above. Cotton holds onto sweat, so on a hot night it goes from comfortable to clammy. A thin cotton voile breathes better than a heavy jersey, but neither dries fast.

Organic cotton pyjamas are grown without synthetic pesticides and fertilisers, which is a real environmental gain and a sensible choice if that matters to you. On your skin at 3am, though, organic cotton behaves like any other cotton. The fibre is the same, so the moisture story is the same. If you sleep cool, either is a good choice. If you sweat at night, the farming method won't change how damp you wake up.

Silk, satin, linen and merino

Silk feels cool and luxurious but shows sweat marks, needs careful hand-washing and costs more again. Satin is usually polyester with a silky finish, and it traps heat. Linen breathes beautifully but creases and can feel rough against sensitive skin. Merino regulates temperature well and suits cooler sleepers. We compared them properly in silk vs satin vs modal and merino vs modal.

So which should you choose?

Choose cotton if you sleep cool and dry, prefer a crisp feel, and are buying on price; choose organic if the farming matters to you. Choose bamboo if you want a soft, cooling budget option and don't mind replacing it sooner. Choose TENCEL™ Modal if you run hot, sweat at night, have sensitive or easily irritated skin, or simply want sleepwear that still feels new after fifty washes. It costs more upfront; it's cheaper per year of wear, and we did the cost-per-wear maths to show it.

The honest bit

If you sleep cool, rarely sweat and like the feel of cotton, you don't need modal. A good cotton set will serve you well for less money, and we'd rather you bought the right thing than ours. Fabric matters most for people whose sleep is already being broken by heat, sweat or itch. That's who we make VELIN for.

Frequently asked questions

Is TENCEL™ Modal the same as modal?

All TENCEL™ Modal is modal, but not all modal is TENCEL™. Generic modal can come from any producer with any standards; TENCEL™ is Lenzing's certified fibre with traceable beechwood sourcing and closed-loop production.

Are bamboo pyjamas better than cotton?

For hot sleepers, often yes: bamboo viscose is softer and more cooling than most cotton. The trade-off is consistency and lifespan. Quality varies widely between makers, and it tends to pill and lose shape sooner.

Are 100% cotton pyjamas good for night sweats?

Cotton breathes well but dries slowly, so once you've sweated into it you stay damp and then get cold. It's fine for mild warmth; for drenching night sweats, a faster-drying fibre like modal is more comfortable.

Is organic cotton better for sensitive skin?

Organic cotton is grown without synthetic pesticides, but the finished fibre feels and behaves much like conventional cotton. For reactive skin, look for OEKO-TEX® certification, a smooth fibre, flat seams and no tags.

Is modal good for summer and winter?

Yes — its strength is regulation rather than warmth or coolness alone. It breathes and wicks in summer, and in winter it avoids the damp-then-cold cycle that makes cotton uncomfortable under a doona.

How do I care for TENCEL™ Modal?

Cold gentle machine wash (a wash bag helps), no bleach, skip the softener, and line dry in shade. It naturally resists wrinkles, so ironing is rarely needed.
