Cooling sheets are made from breathable fibers like cotton, linen, bamboo lyocell, TENCEL™, or nylon/spandex blends that wick moisture and promote airflow.
The term “cooling sheets” doesn’t point to one regulated material — it’s a marketing label covering several very different fabric families. What unites them is a goal: moving heat and sweat away from your skin while you sleep. Most products fall into two camps: natural fibers prized for breathability, and synthetic performance blends engineered to wick moisture rapidly.
Understanding which material suits your sleeping habits matters more than any brand name. The table below breaks down the main options so you can match a fabric to your needs, whether you sleep hot or just want a crisper feel.
What Fabrics Are Used In Cooling Sheets?
The most common cooling sheet materials are cotton, linen, bamboo-derived fibers, lyocell/TENCEL™, and synthetic blends like nylon/spandex. Each performs differently for hot sleepers, and “cooling” can refer to the weave, the fiber, a finish, or an added yarn technology.
Cotton — particularly percale weaves — stays breathable and crisp, making it a reliable choice. Linen offers exceptional airflow and moisture management, though it wrinkles easily. Bamboo lyocell and TENCEL™ are semi-synthetic fibers derived from wood pulp; they feel smooth, breathe well, and regulate moisture effectively. On the synthetic side, nylon/spandex blends and poly-nylon mixes are engineered to pull sweat off the skin and dry fast, often with a silky, cool-to-the-touch feel.
How Do Cooling Sheets Actually Work?
Cooling sheets work through two mechanisms: breathable construction and moisture-wicking fibers. A loose, airy weave lets body heat escape, while moisture-wicking materials draw sweat away from your skin so it can evaporate instead of trapping warmth against you.
Some brands add extra technology on top of the base fabric. Rest’s Evercool®+ line, for instance, combines a nylon and spandex blend with IONIC+ Antimicrobial Technology silver yarn for moisture management. Wicked Sheets uses a silk-weight poly-nylon fiber blend with a UV-cut component, claiming the material stays 2 to 3 degrees cooler to the touch. SHEEX offers different constructions across collections — its Nightfall™ set uses nylon/spandex, while the Arctic Aire•MAX set is made from 100% TENCEL™ Lyocell.
These brand-specific technologies (brrr° patented nylon, IONIC+ silver yarn, UV-cut fibers) are not universal cooling standards. They’re proprietary features tied to a specific model, so judge each product on its own material composition rather than the marketing name.
Which Material Is Best For Hot Sleepers?
There’s no single “best” cooling material — the right choice depends on whether you sweat heavily, prefer a crisp or silky feel, and how much you’re willing to spend. The table below compares the main options across the factors that matter most.
| Material | Key Strength | Best For |
|---|---|---|
| Cotton (percale) | Breathable, crisp feel | Classic comfort; all-season use |
| Linen | Superior airflow, moisture-wicking | Hot sleepers; humid climates |
| Bamboo lyocell / viscose | Smooth, breathable, moisture-regulating | Softness seekers; night sweaters |
| TENCEL™ Lyocell | Breathable, eco-friendly, moisture control | Hot sleepers wanting sustainable options |
| Nylon/spandex | Fast-drying, cool-to-touch | Athletic sleepers; heavy sweaters |
| Polyester/microfiber | Affordable, wrinkle-resistant | Budget buyers; less intense cooling needs |
If you tend to drench the sheets, a moisture-wicking synthetic like nylon/spandex often outperforms natural fibers. If you just run warm and want a crisp, breathable feel, percale cotton or linen delivers reliable results. For a balance of softness and cooling, bamboo lyocell and TENCEL™ are strong middle-ground picks.

Do Cooling Sheets Really Work?
Yes — but within limits. Cooling sheets can genuinely reduce nighttime overheating by improving airflow and moisture management, but they won’t override a warm room or heavy bedding. They’re most effective when paired with comfortable bedroom temperatures (around 65–70°F) and breathable pajamas.
One caveat: “cooling” isn’t a standardized label, and manufacturers use the term loosely. Always check the specific product page for the exact fabric composition and weave. A sheet’s cooling performance depends on its construction — a loose percale weave, a moisture-wicking fiber, or a coolant finish — so two products both labeled “cooling” can feel completely different. Rest’s product pages identify the fabric and technology for each sheet type, which is the right level of detail to look for before buying. Claims about cooler touch should be tied to the exact model and material, not taken as a blanket promise.
FAQs
Are bamboo or eucalyptus sheets naturally cooling?
Yes, bamboo and eucalyptus sheets are naturally breathable and moisture-wicking. Both are derived from wood pulp and made into lyocell or viscose fibers that feel smooth and cool against the skin. They perform well for hot sleepers, though eucalyptus lyocell is often praised for being more sustainably produced than bamboo viscose.
What is the coolest fabric for sheets?
Linen and percale cotton are among the coolest natural fabrics because their loose weaves allow maximum airflow. Among synthetics, nylon/spandex blends feel cool to the touch and dry quickly, making them effective for heavy sweaters. The coolest choice depends on whether you prioritize breathability or moisture-wicking performance.
Do cooling sheets stop night sweats?
Cooling sheets can reduce night sweats by wicking moisture and promoting airflow, but they aren’t a cure. Night sweats often stem from medical conditions, hormones, or room temperature. Sheets help manage the discomfort, but persistent night sweats warrant a conversation with your doctor.
