5 Cooling Bed Sheet Materials Perfect for Hot Summer Nights

When the warm nights arrive, the wrong bed sheets can turn sleep into a sticky, restless ordeal fast, while the right ones can keep you cool enough to drift off. The fabric your sheets are made from does most of that work, because it decides whether heat and moisture escape or build up against your skin. So if summer sleep is a struggle, switching to a genuinely cooling material is one of the easiest changes you can make.

Here are five cooling bed sheet materials perfect for warm nights, along with some tips on how to pick the right one for the way you sleep in summer.

What Makes a Sheet Cooling

Before the materials, it's worth knowing what you're actually after, because "cooling" comes down to two things. The first is breathability: an open, airy weave lets warm air and humidity pass through rather than trapping it next to you. The second is moisture management: a fabric that draws sweat away from the skin and lets it evaporate keeps you dry, and dryness is a big part of feeling cool.

Natural and natural-derived fibres tend to do both well, which is why Simba's summer-friendly bedding is built around fabrics like cotton, linen and Tencel rather than heat-trapping fabrics. The five below each handle heat and moisture in their own way, so the best one for you depends on whether you prefer crisp, soft or naturally textured sheets.

1. Brushed Tencel

Tencel is something of a sleep superhero for hot nights. Made from a natural, wood-derived fibre, Simba's Brushed Tencel bedding is superbly cooling and strongly moisture-wicking, drawing sweat away and helping it evaporate so you stay dry through the night. What sets it apart is that it pairs that cooling performance with a gently brushed, velvet-soft finish.

That combination is unusual: most fabrics make you choose between soft and cool, whereas Brushed Tencel gives you both at once. If you love the softness of a brushed fabric but can't bear the heat that usually comes with it, this is the one to reach for in summer.

2. Cool Linen

Linen is the classic warm-weather fabric, and for good reason. Simba's Cool Linen is a heat-regulating linen-Tencel blend with a naturally textured, breathable structure that lets air move freely and heat escape. It has that characteristic cool-to-the-touch feel that makes climbing into a linen-dressed bed so welcome on a hot night.

Blending the linen with Tencel softens the slightly rustic character of pure linen, so you keep all the airy, heat-regulating breathability while gaining a smoother, gentler hand. For sheer hot-night performance with an effortlessly relaxed look, Cool Linen is hard to beat.

3. Cotton Percale

If you like the crisp, fresh feel of hotel bedding, cotton percale is the cooling classic. Percale is a plain, tightly woven cotton with a smooth, breathable, hotel-quality finish that feels cool and crisp against the skin. It deliberately lacks any fuzzy warmth, which is exactly what makes it so suited to summer.

Cotton's natural breathability lets heat and moisture pass through rather than building up, and the crisp percale weave enhances that cool, airy sensation. For anyone who associates a good night's sleep with clean, cool, crisp sheets, percale is a dependable summer choice.

4. Soft Muslin

Muslin is made for warmer nights, and Simba's new Soft Muslin is cloud-like, light and airy, with an open, breathable cotton structure that keeps air moving and stops heat building up. It's gentle on the skin and, characteristically, grows softer with every wash, so it only improves with use.

Its lightness is the appeal: muslin feels barely there on a hot night, which is exactly what many people want when it's too warm for anything substantial. If you find most bedding too heavy in summer and want something airy and soft, muslin is a lovely option.

5. Egyptian Cotton

For those who want luxury without the heat, Egyptian cotton offers cooling comfort with a more indulgent feel. Simba's Egyptian Cotton is smooth, silky and breathable, combining a luxurious hand with the natural temperature management of quality cotton. It feels elegant and substantial while still letting heat and moisture move away from the body.

It's the choice for anyone who wants their summer bedding to feel like a treat as well as a cool place to sleep. The breathability keeps it comfortable on warm nights, while the silky finish gives it a sense of occasion that crisper fabrics don't quite match.

Finding Your Cooling Material

With five cooling fabrics to choose from, the decision comes down to feel: cool and soft with Brushed Tencel, naturally textured with Cool Linen, crisp and fresh with Cotton Percale, light and airy with Soft Muslin, or silky and luxurious with Egyptian Cotton. Each keeps you cooler than a heat-trapping synthetic, so you're choosing texture as much as temperature.

When you're ready to upgrade for summer, Simba's cooling bedding range brings all five of these breathable fabrics together in the full run of UK sizes. Match the fabric to how you like your sheets to feel, and warm nights become far easier to sleep through.

A Note on Colour and Care

Beyond the fabric itself, a couple of small choices help cooling sheets perform at their best through summer. Washing breathable natural fabrics gently and avoiding heavy fabric softeners keeps the fibres open and airy, since softener residue can coat the threads and slightly dull their breathability over time. A cool or warm wash, rather than a very hot one, also looks after fabrics like Tencel and linen and keeps them feeling fresh.

It's also worth thinking about your whole sleep setup rather than the sheets alone. Even the most breathable fabric works better in a cool, dark, well-ventilated room, so pairing your summer sheets with an open window, lighter sleepwear and a low-tog duvet, or none at all, lets the material do its job. The sheet sets the surface against your skin, but it performs best as part of a bed that's been dressed for the season from the mattress up.

FAQs

There's no single coolest fabric, but breathable, moisture-wicking ones lead the way. Brushed Tencel is exceptional for combining cooling with softness, while linen is famously breathable and crisp cotton percale feels cool and fresh. The best for you depends on the feel you prefer.

Both are good, but they feel different. Tencel has particularly strong moisture-wicking and stays soft, which suits hot sleepers who want softness. Crisp cotton percale feels cool and fresh to the touch. Choose Tencel for soft cooling, percale for a crisp, airy feel.

Yes. Linen's loosely woven, textured structure is highly breathable and manages moisture well, with a cool-to-the-touch feel. A linen-Tencel blend keeps that breathability while feeling softer and less creased than pure linen, making it a strong summer choice.

Light, airy fabrics like Soft Muslin and breathable linen suit very warm nights, as they feel barely there and let heat escape. Pair cooling sheets with a low-tog duvet, or no duvet at all, to stay comfortable when the temperature climbs at night.

A significant one. The sheet is the layer against your skin, so a breathable, moisture-wicking fabric lets heat and sweat escape, while a dense synthetic traps them. Switching to a breathable, cooling material is one of the simplest and most effective ways to sleep cooler through summer.
