Ready to stop worrying about sweat stains?

1UP Guard™ is a superabsorbent patch that sticks to your underarm skin and catches sweat before it soaks into your shirt and shows up as a stain. The core absorbs up to 20x its weight in moisture, and each patch is made for up to 8 hours of wear. It's about as thick as a penny, so it lies flat against your skin under a sleeved shirt.

The Discovery Kit offers one patch in each of two neighboring sizes. Try both and find your fit before choosing a multipack.

  • Find your fit: Compare two sizes: a closer fit and extra coverage. See which you prefer.
  • Reach for the clothes you've been avoiding: Heather gray, linen, silk, any color or material that darkens when wet.
  • Don't sweat it: Raise your hand, hug a friend, take off your jacket. Up to 8 hours without a second thought.
  • Try it for 30 days: Full refund if it is not right for you. Keep the patches.

"I've dealt with underarm sweat stains since I was a teenager. I made 1UP Guard for one thing: the stains everyone can see"
- Bryan, founder

Arms up. High & Dry.

The 1UP Guard™ difference

☑️ Wearable:

  • Worn on your skin, it moves with you through the day under any sleeved shirt.

☑️ Shaped for the underarm:

  • Curved edges and side notches conform to the crease where your arm meets your torso. Four sizes for a wide range of fits.

☑️ Gentle silicone adhesive:

  • Holds through the day, is designed to come off gently, and allows limited repositioning while you apply it.

☑️ Longer-lasting clothes:

  • Less sweat reaching the fabric means less scrubbing and fewer harsh stain removers, so your favorite shirts stay in better shape for longer.

☑️ Discreet:

  • Ultra-thin, flexible, and virtually undetectable under clothing, at work, on a date, or anywhere in between.

Materials

  • Superabsorbent core: An unbleached blend of plant-based fibers and superabsorbent polymers, with a grid-patterned skin contact layer that draws moisture into the core.

  • Backing tape: Thin, breathable tape with bi-directional stretch and a medical-grade silicone adhesive.

  • Latex-free & biocompatible: The backing tape and absorbent core are each tested to ISO 10993 biocompatibility standards.

Such a great product! It absorbs a ton of moisture! I had to remove 1 star because the paper covering the adhesive side is extremely difficult to remove (no matter how slow you peel, whether you make the recommended cuts or not, or the direction you peel it. I’ve tried everything). The one flaw with these is the silicone adhesive is so delicate, and the paper covering does not pull off of it easily, so when the paper backing is removed it stretches and wants to roll inward on itself. It’s impossible to un-stick after it has rolled and stuck to itself so that section of the patch is not sticking to your skin as well as the rest. I usually lose half my patch this way because once an area is loose the rest comes off pretty quickly and just flops around. :-)

We're really glad the patches are absorbing well for you. Thank you for giving 1UP Guard a real try and for such a detailed review. It's exactly the kind of feedback that helps us improve.

For anyone reading: the peel step can take some practice, and our Pit Crew page collects application and peel techniques that have worked for other customers. If you have any questions, feel free to reach out to us at info@1upguard.com at any time.
