Alta is the most technologically advanced towel you will ever use.

Most towels are dirtier than you think. That musty smell they get is actually bacteria and mold. The two love to grow on moist, damp fibers and can be easily seen under a microscope. That's why Alta was engineered with unique technologies to kill microbes before they get a chance to grow—keeping you and your towel clean and fresh after every shower.

Cotton is one of the softest, most absorbent materials in the world. Alta is made with 100% long-staple cotton sonically infused with copper, meaning it's hypoallergenic and ultra-plush for those with even the most sensitive skin.

And while copper has been used as an antibacterial agent for centuries, it has also been scientifically proven to promote skin health and elasticity. We've harnessed these unique properties and put them to use for the ultimate drying experience.

Made in Turkey.

  • Antimicrobial: Copper-infused fibers self-sterilize to kill 99% of bacteria and mold.
  • Ultra-plush:Weighs in at 650 grams per square inch (GSM), meaning a soft, luxurious feel.
  • Super absorbent: Densely packed cotton fibers wick away moisture instantly.
  • Hypoallergenic: Made with 100% cotton and no harsh chemicals so it's safe for even the most sensitive skin.
  • Deodorizing: Breaks down odor-causing molecules and bacteria so it never gets musty.
  • Eco-friendly: EPA approved manufacturing process ensures the copper particles won't leach into the water.
  • Infused to Last: No loss of antimicrobial efficacy even after 100 washes.
  • Anti-aging: Copper has been scientifically proven to reduce the appearance of fine lines and wrinkles and help promote skin elasticity.

Alta features CottonX, a proprietary technology that turns cotton into a self-sterilizing fabric and germ-killing machine. Using ultrasonic waves, copper oxide is permanently embedded into the cotton fibers so it never washes off.

  • Alta has undergone independent testing by third-party laboratories to ensure it’s effects
  • Lab tests reveal that > 99% of germs are killed even after 100 industrial washes (AATCC-100)

Simply Cotton & Copper

There are just 2 things in our towel: cotton and copper. Cotton is extremely soft and super absorbent while copper's antimicrobial effects have been used for hundreds of years. with the most advanced technology, Alta combines them into form an all-natural towel that never gets musty.

Here’s how it works:

Using CottonX technology, copper oxide is infused into the cotton fibers with ultrasonic (sound) waves. This creates a permanent attachment at the molecular level. This proprietary process is the only technology that delivers antimicrobial effects to 100% cotton.

It Comes From Within

Most antibacterial treatments are a silver coating that washes off with every use—ours doesn't. Our OURA towels are infused (not coated!) with copper. This means that it is permanently embedded into every fiber of cotton, so your towel stays cleaner longer.

Here’s how it works:

Silver coatings chip and wash off with every use, leaching into our waterways and losing its effects after as few as 10 washes. But because our EPA-approved manufacturing process sonically infuses copper into cotton, there's no risk of that with OURA towels. Instead, the copper in Alta stays attached to the cotton fibers even after 100 washes - all with no loss of antimicrobial efficacy.

GSM stands for grams per square meter and it indicates how plush a towel is. Thin, lightweight towels tend to be under 400 GSM. Average-weight towels, like beach towels, are usually 400 - 600 GSM. Any towel above 600 GSM is considered (by the experts, of course) to be a luxury towel. OURA’s Alta towel hits the sweet spot of 650 GSM: it is ultra-absorbent and eternally soft, without being inconveniently thick and dense. In other words, it’s top-quality.

If a towel isn’t absorbent, can you even call it a towel? We made sure Alta soaks up water. Rather than twisting shorter fibers into compact threads that reduce the absorbency, Alta uses zero-twist loops which are far more absorbent and soft. Additionally, we removed the doby (the patterned sections of towels that don’t soak up water) to maximize the available area of the towel. Finally, it’s ultra-plush coming in at 650 GSM.

No! Alta Towels are made with only long-stable cotton. These long staple lengths mean that the towel is extremely resistant to shedding. There’ll be no lint while you dry off!

Each Alta Towel starts with the best natural materials. We use 100% long-staple cotton which is known for its exceptional durability and softness. The cotton is sonically infused with copper in a proprietary process that gives it antimicrobial, germ-killing properties using all-natural hypoallergenic materials. This unique process makes it perfect for all types of sensitive skin.

After this, the Alta Towels are spun together with a luxurious, ultra-plush density of 650 GSM that results in a thick, snuggly towel with unmatched comfort and absorbency.
