You’re not alone. This is your moment—your sleep, your way.
Tundraen’s here for the nights you’ll never want to give up.
Sheets? What’s the big deal?
Look, we get it—sheets don’t sound like headline news. You’re probably thinking, “They’re just fabric, right?”
But if you’ve ever woken up to that damp, clingy mess, you might pause. We sure did. Turns out, dryness isn’t just a luxury, it's a must for a good night's rest.
We found a little secret in eucalyptus trees—those tall, leafy wonders—and it’s got us wondering: could your bed do more for you?

Dry Could Feel Good…
Imagine sliding into bed and… it’s not sticky! Just a smooth, dry escape.
We craft these sheets from eucalyptus fibers because they’ve got a knack for keeping things dry—way beyond what typical fabrics pull off. Research says eucalyptus fibers soak up moisture 65% faster than the average sheet (Textile Science Advances, 2023).
We’re not wizards—those night sweats might still visit—but the dampness? It’s whisked away before it settles. Feels crisp, cool, like a fresh start. Ever think a dry bed could shift your whole night?
You’re still wondering, maybe picturing it. Here’s what we guarantee:

Dryness That Lasts
It doesn’t just grab moisture—it evaporates it away. That’s because its fibrils—those little hair-like bits inside the fiber—act like a sponge, pulling water in quick.

Cool, Gentle Relief
Those fibers let air dance through — cool air flows in, heat slips out. Think a subtle 2°F dip in perceived heat.

Earth’s Own
No chemical sludge, just nature looped back. These trees need zero pesticides—cotton’s drowning in them (FAO stats). They are good for the earth, even better for you.

The Feel
Silky, crisp, like a breeze through the woods. Testers say it’s “addictive”—75% preferred it over bamboo viscose (our main opponent!) in a blind feel-test (Textile Trends, 2023).

Your Best Bet
These eucalyptus lyocell sheets aren’t some throwaway fix—they’re in it for the long haul. Woven from nature’s tight-knit fibers, they shrug off fraying and sagging like it’s nothing.

A Gift to Yourself
A decade of cool, clean nights awaits you. Years of waking up sharper, brighter—more you, while still being the same sheets.
Like a sponge? Isn’t that bad if I want to keep everything dry?
Well thought!
Think of it like this: it can’t keep you dry without first absorbing your shiny moisture, can it? Anyway, absorption’s only half the story. The same structure lets it release that moisture into the air just as fast. Research from Fibers & Polymers (2022) found lyocell’s evaporation rate beats out most plant-based fabrics by 50%, thanks to its open, breathable weave and natural air channels.
Pair that with a 2023 Journal of Environmental Textiles finding: Lyocell cuts bed microclimate heat by about 2.7°F versus stuffier materials, thanks to less humidity buildup. That’s not a room temp drop—it’s your skin and bed feeling fresher, drier, cooler. A 2021 sleep study from the American Academy of Sleep Medicine says even a 2-degree drop boosts deep sleep by 15%.

“This Feels Like Home”
A few weeks in, and it’s not even a question anymore. Your bed’s just dry, night after night — no exceptions. That cool, silky touch greets you like an old friend.
We hear it from folks all the time: once you go Tundraen, it’s just your way. And here’s the quiet bonus: Eucalyptus grows light on the land—20% less carbon footprint than cotton (Global Ecology Report, 2021)—so you’re sleeping easy in more ways than one. It’s not just sheets; it’s your little slice of calm.
Menopause's sweaty nights meet their match here.
Other sheets try—cotton holds sweat, bamboo viscose masks its flaws with hype, and polyester is... polyester.
