Waking rested and cool in Second Skin sheets

Not all cooling sheets are equal

Stop sleeping hot.

Most sheets trap your body heat and hold it against your skin all night. Second Skin is different — smart botanicals sense when you warm up and cool you down, naturally, before sweat wakes you.

Design note: swap for thermal-style shot of a cotton bed at 3am when produced.

Feel what’s happening

This is why you keep waking up at 3am.

Cotton absorbs your body heat and gives it right back, hour after hour. Your temperature climbs, sweat follows, and your deepest sleep gets cut short — night after night.

Second Skin breaks the cycle: heat-responsive botanicals, moisture-wicking marine proteins, and breathable bamboo — nothing between you and a cool night’s rest.

The science of staying cool

Cooler sleep, clinically supported.

14 minfaster sleep onset from a 2°F drop in skin temperature
40%fewer nighttime wake-ups with cooler sleep conditions

Second Skin Sheets vs. your old sheets

If you run hot at night, your sheets are either helping — or making it worse.

Ordinary cotton & microfiber
  • Traps your body heat — warms all night
  • No response when your temperature rises
  • Night sweats wake you at 3am
  • Bacteria and odor build up between washes
  • Rough against sensitive skin
Second Skin SheetsStays cool
  • Botanicals activate the moment you warm up
  • 4x cooler than regular cotton
  • 8/10 sleep through the night
  • 99.9% of bacteria naturally eliminated
  • 2x softer than silk
