What's this about again?
Product
What is 1UP Guard™ sweat solution?
1UP Guard™ is an underarm sweat protection patch designed for anyone looking to guard against visible underarm sweat stains, including people who experience heavy or excessive sweating.
It adheres directly to the skin and acts as an absorbent barrier between sweat and your clothes, helping prevent visible underarm stains.
If deodorants and antiperspirants haven't solved your underarm sweat stains, 1UP Guard™ takes a different approach - absorbing sweat before it reaches your clothes.
Is this product a deodorant or antiperspirant?
No, 1UP Guard™ patches are neither a deodorant nor an antiperspirant. It does NOT prevent sweating.
It is an advanced barrier and absorbent patch. It works by physically adhering to the skin and using its superabsorbent core to lock away moisture and prevent sweat from reaching your clothing.
Critically, 1UP Guard™ patches are not a drug product and does not contain any active ingredients like aluminum chloride or aluminum zirconium.
What is a Superabsorbent?
A superabsorbent is a material that can absorb and retain many times its own weight in liquid. These materials, also known as Superabsorbent Polymers (SAPs), are widely used in fluid-control and moisture-management products.
In 1UP Guard™ patches, the superabsorbent core is the primary layer that absorbs and locks away sweat, helping keep your clothes dry and comfortable throughout the day.
What's so great about Silicone adhesives?
It's all about a secure hold that stays gentle on your skin.
Unlike traditional acrylic or rubber-based adhesives, our silicone adhesive forms a low-trauma bond, making it well-suited for the delicate underarm area. It's also repositionable during application, allowing a degree of adjustability.
The polyurethane backing the adhesive sits on is also breathable - engineered to let moisture vapor pass through rather than trapping it against the skin - and the adhesive is latex-free.
It’s a skin-friendly solution designed to keep you comfortably protected through the day.
What's with the shape?
The shape of our patch is the result of a lot of thought and care to provide effective coverage for the unique and challenging underarm area.
The underarm is an awkward space that changes shape with every movement of your arm. The arc cuts along the edges and the pill-shaped cutouts in the middle allow the patch to flex and move with you, ensuring it stays securely in place with minimal discomfort.
To further ensure a great fit for a wider range of folks, our patches are available in multiple sizes, so you can find the right one for you and stay protected throughout your day.
How do I know what size to buy?
Selecting the correct size is the most important step for comfort and a secure fit. We offer several tools to help you find your ideal fit:
- Use Our Size Estimator Tool: Start on our Size Guide page and use the custom Estimator. By inputting basic information (like height, weight, etc.), it will provide an estimated size or size range (e.g., "Between Size 2 and Size 3").
- Visual Reference: To help you envision the sizes, the Size Guide also uses common objects as references, such as a Standard Credit Card (similar to Size 1's Absorbent layer) and a Standard Index Card (similar to Size 3's Absorbent layer).
- The Discovery Kit: If you are a new customer, we highly recommend starting with The Discovery Kit (mixed sizes). This allows you to physically try on the size range suggested by the Estimator and confirm the perfect size for your unique underarm contours.
💡 Tip: Initially, try to match up the Absorbent layer of the patch with your axillary (underarm) hair-bearing area. The choice between a snug fit or extra coverage is ultimately up to your personal preference.
What is the difference between the Discovery, Moment, and Reserve Kits?

And how do I use it?
Usage
How do I use 1UP Guard™ patches?
Much like applying an adhesive bandage, with a few extra considerations.
Fold the patch first, then slowly remove one half of the adhesive's protective liner (the Clear Liner covering the sticky side). Always peel slowly, gently, and carefully, following the natural perimeter of the adhesive border. Maintain a 90° arm angle laterally to your torso (straight out to the sides).
Align the patch with your underarm area and apply directly to the skin. Repeat for the upper half - again, peeling slowly along the border perimeter - and once firmly secured, remove the decorative paper backing liners (the non-adhesive top layer).
TL;DR FOLD - PEEL - STICK - PEEL may be the easiest way to think about it.
Please refer to our Instructions page for Application details and Tips.
💡 Looking for a meticulous, high-precision layout? Check out The Precision Peel Method directly below.
What is the Precision Peel Method?
The Precision Peel Method is our favorite advanced application technique, recommended for achieving an ideal, ultra-flat adhesive border layout.
While our standard method works beautifully for quick, everyday wear, this alternative technique involves making swift vertical snips through the Clear Inner Liners with clean scissors before peeling.
With the Clear Inner Liners divided into four smaller, manageable quadrants, this method facilitates the patch's premium adhesive border to remain flat, undisturbed, and perfectly primed for a maximum-performance skin bond. For a step-by-step visual demonstration of this method, please check out Step 2A on our Instructions Page and on the back of each patch's cold-seal pouch.
How does it feel to wear the patch?
When you first apply the patch, you may notice a new sensation, but 1UP Guard™ is designed to stay understated and inconspicuous under clothes. It is ultra-thin, lightweight, and flexible, conforming to the natural curves of your underarm.
Any initial awareness tends to fade quickly. Thanks to our soft materials and gentle silicone adhesive, the patch is engineered to move with you, not against you.
The patch is designed to be easy to forget throughout the day - letting you focus on staying confident about underarm sweat stains, not on the patch itself.
How long does one patch last?
Our patches are engineered to provide up to 8 hours of wear, which is designed to get you through a workday or a long event.
The exact wear time can vary from person to person, depending on factors like your activity level and personal sweat rate. We designed the patches for comfortable, single-day use to balance reliable performance with gentle wear on your skin.
Can I wear the patch overnight while I sleep?
We do not recommend wearing the patches overnight.
They're engineered for up to 8 hours of comfortable, single-day use during work, events, or regular daily activity. To help minimize the risk of skin irritation and to prevent the adhesive from bonding too firmly over time, please remove the patch at the end of the day using the gentle removal methods before going to sleep.
Are the patches reusable?
Our patches are designed for single use only.
For the best performance, we do not recommend using a patch more than once. Reusing a patch can compromise the effectiveness of the adhesive and the absorbent core, which is designed to provide reliable protection with one-time use.
How much sweat does a patch absorb?
While the amount of sweat a patch can absorb depends on your personal sweat rate, we've designed our patches to handle a significant amount of moisture.
The core of each patch is comprised of an advanced superabsorbent material that can hold up to 20 times its own weight in moisture, effectively locking away sweat to keep your clothes dry through the day.
Do 1UP Guard™ patches help prevent or reduce body odor?
1UP Guard™ is designed to prevent visible underarm sweat stains by acting as a physical, absorbent barrier between sweat and your clothes. It is not a deodorant or antiperspirant and is not formulated to address body odor.
Some people find that keeping the underarm drier feels fresher, but the patch is not designed or tested to reduce body odor, and we make no odor-reduction claims.
Important Note: If odor control matters to you, we recommend continuing to use your preferred deodorant or antiperspirant on the areas of the underarm that are not covered by the patch.
Can I wear it with deodorant or antiperspirant?
For our patches to provide the best possible performance, they must be applied directly to clean, dry skin.
Most deodorants and antiperspirants leave behind a residue or contain ingredients that can interfere with our gentle silicone adhesive, preventing the patch from sticking securely.
For this reason, we recommend applying the patch to a thoroughly clean and dry underarm before you use any other products. If you still wish to use a deodorant for odor control, you can apply it to other areas of your underarm not covered by the patch.
Is it waterproof? Can I swim or shower while wearing it?
Our patches are designed to be highly breathable and moisture-resistant, but they are not waterproof.
Because the core layer is engineered to absorb moisture, the patch is not suitable for activities like swimming or showering. For the best performance, please apply the patch to clean, dry skin.
Can I work out with the patch on?
We do not recommend wearing the patches during a workout or any other vigorous activity.
Intense arm movements may interfere with the adhesive, causing the patch to shift or lose its hold. For the best comfort and hold, the patches are best used for daily wear during regular activities.
Can 1UP Guard™ patches be used on other parts of the body?
1UP Guard™ patches were specifically designed and engineered for the unique, high-movement geometry of the underarm (axilla) to ensure maximum adhesion, comfort, and coverage in that area.
For this reason, we cannot recommend or guarantee performance for use on other areas of the body. If you choose to use the patch on a different area, please note that the patch may not conform optimally and that such use is at your own discretion and risk. We always advise performing a patch test on a small area of skin first.
A little extra care goes a long way
For Your Comfort & Safety
How do you ensure product quality & safety?
Our patches are manufactured by an experienced U.S. manufacturer that operates FDA-registered, certified cleanroom facilities and specializes in precision adhesive converting.
We use components sourced from leading suppliers in the U.S. and E.U. The backing tape and absorbent core have each been independently tested for cytotoxicity under ISO 10993-5, and the backing tape has additionally passed ISO 10993-10 skin-irritation testing. The silicone adhesive is also latex-free.
Can I use this on broken, irritated, or sunburnt skin?
No. For your safety and comfort, our patches are designed for use on healthy, intact skin only.
The silicone adhesive and absorbent core are designed to be gentle and non-irritating for everyday use, but applying them to compromised skin could cause further discomfort or worsen the condition. Please wait until your skin is fully healed before using the patches.
Can the patch be worn with underarm hair?
While the silicone adhesive is gentle, applying the patch to shaved, trimmed, or hair-free skin will always yield the best adhesion and the most comfortable, low-trauma removal.
If you have significant underarm hair, we strongly recommend trimming or shaving the area where the patch will be applied to support a secure hold and to minimize discomfort upon removal.
How do I remove the patch properly?
The underarm is a sensitive area, and the key to a gentle removal is to go LOW & SLOW. Never rip the patch off like a conventional adhesive bandage, as this can increase the risk of skin irritation.
We recommend one of the following methods for a smooth and comfortable experience:
- The Roll Method: Carefully lift a corner of the patch. While supporting the skin at the peel line with your other hand, gently roll the patch back over itself with your fingertip.
- Using a Moisturizer: If you encounter resistance while rolling, apply a small amount of petroleum jelly or moisturizer to the peel line as you slowly roll the patch away. This will help soften the adhesive.
- The Stretch Method: Carefully lift an edge and stretch the patch slowly and horizontally along the skin, away from the center of the patch.
For more detailed Removal information & tips, please visit our Instructions page.
What should I do if there is adhesive residue? Can I use alcohol to remove it?
While our patches are designed for a clean removal, in the rare case that any residue remains, a small amount of petroleum jelly or moisturizer can help soften it before washing the area. Commercial adhesive-remover products (the kind used for bandages) are also an option.
Note that this silicone-based adhesive is not readily dissolved by alcohol, so we don't recommend using alcohol for removal.
What should I do if my skin is sensitive or gets irritated?
While our patches are designed to be gentle on sensitive skin, the underarm area can be particularly delicate. If you know you are sensitive to medical adhesives, we recommend consulting a medical professional prior to use. As with any skin-contact product, individual reactions can vary, so we suggest a small patch test first.
For extra precaution, a skin-barrier product (the kind designed to sit between skin and an adhesive) can act as a protective layer.
In the rare event that skin irritation occurs despite proper use, stop using the patch and give the area time to recover. If irritation persists, discontinue use and consult a medical professional.
So...when and how will I get my stuff?
