Best Pillowcases for Night Sweats
By Claire Donovan | Updated March 2026
Night sweats are different from being a hot sleeper. The issue isn’t just temperature — it’s moisture. Sweat accumulates against your face and pillow, creating a damp, uncomfortable surface that disrupts sleep and can leave you waking up feeling clammy.
The material that helps most isn’t necessarily the most breathable — it’s the one that moves moisture away from skin fastest. Here are our picks.
Why Moisture-Wicking Matters More Than Breathability for Night Sweats
“Breathable” fabrics allow air circulation, which helps with general warmth management. But for night sweats specifically, you need moisture transport — the ability to absorb sweat from skin and move it through the fabric where it can evaporate.
Bamboo lyocell and eucalyptus Tencel have micro-gap fiber structures that do this faster than cotton or silk. The result is a fabric that stays drier against your skin even when you’re actively perspiring.
#1 Best for Night Sweats: Mellow Cooling Bamboo Pillowcase
Material: Bamboo Lyocell | GSM: ~300 | Machine Washable
Bamboo lyocell’s fiber structure is specifically suited to moisture management. The micro-gap cross-section absorbs perspiration quickly and releases it through evaporation — so even when you’re sweating, the fabric surface stays relatively dry.
Mellow’s cooling bedding collection focuses on exactly this use case: hot sleepers and night sweaters who need genuine performance, not just marketing claims.
Moisture-wicking: ★★★★★
Cooling: ★★★★★
Feel: Silky-smooth, softer than percale cotton
Care: Cold machine wash, low heat or air dry

#2 Best Premium for Night Sweats: Eucalyptus Tencel Pillowcase
Material: Eucalyptus Lyocell (Tencel™) | GSM: 280–320
Eucalyptus Tencel from Lenzing uses a closed-loop manufacturing process — more sustainable than bamboo viscose — and produces fibers with comparable moisture-wicking performance to bamboo lyocell. Some testers find eucalyptus Tencel slightly softer and more temperature-stable than bamboo.
If sustainability is a priority alongside night sweat management, Tencel is the pick.
Moisture-wicking: ★★★★★
Cooling: ★★★★★
Sustainability: Best in category
Care: Cold gentle wash, air dry preferred
#3 Best Cotton Alternative for Night Sweats: Parachute Percale Pillowcase
Material: 100% Long-Staple Cotton | TC: 400 | Weave: Percale
If bamboo or eucalyptus isn’t available or within budget, percale cotton is the best cotton option for night sweats. The open weave breathes better than sateen and allows moisture to evaporate, though it doesn’t wick as aggressively as plant-based lyocell fibers.
For mild to moderate night sweats, percale performs adequately. For heavy night sweats, the bamboo options above will perform noticeably better.
Moisture-wicking: ★★★☆☆ (better than sateen; lower than bamboo)
Cooling: ★★★★★
Care: Easy — machine wash and dry
What Doesn’t Work for Night Sweats
| Material | Problem |
|---|---|
| Sateen cotton | Dense weave holds moisture against skin |
| Polyester satin | Doesn’t absorb sweat; redistributes it |
| Silk | Temperature regulates but doesn’t wick heavy moisture effectively |
| Flannel | Designed to hold warmth and moisture |
| Jersey knit | Absorbs but holds rather than evaporates |
Complementary Steps for Night Sweats
A cooling pillowcase helps, but for significant night sweats, combining it with other bedding changes maximizes impact:
- Cooling mattress pad or protector — addresses the larger sleep surface where most heat builds
- Breathable duvet — down alternative or eucalyptus fill breathes better than traditional down
- Pillow protector — waterproof layer protects the pillow itself, extends washing intervals for the pillowcase
Together, these create an environment where heat and moisture have somewhere to go rather than building up through the night.
