Purple CGM Adhesive Patches 20 Pack - Long-Lasting Waterproof Cover

In this review we look at a 20 pack of purple adhesive patches designed to hold Dexcom G7 and Stelo continuous glucose monitor sensors in place. The bottom line: these patches are for people who need a waterproof, breathable overpatch that can extend sensor wear for 10-15 days and survive showers, swims and sweaty workouts. The reviewer found the material comfortable and skin-friendly, with a reliable waterproof seal when applied correctly, though a few users reported mixed stickiness around edges after several days.

Key Features

• 100% Compatibility: Designed specifically to fit Dexcom G7 and Stelo CGM sensors so users can expect a tailored cutout and secure fit without trimming.
• Long-Lasting Hold: Built to keep sensors attached for 10-15 days, reducing mid-wear detachment and the need for frequent reapplication.
• Waterproof and Sweatproof: The adhesive seal stands up to showers, swimming and heavy perspiration when the patch is blotted dry after exposure to water.
• Skin-Friendly Materials: Made from medical-grade adhesive that is latex-free, zinc oxide-free and hypoallergenic to minimize irritation during extended wear.
• Easy Application: The patch is split into five parts and pre-cut to simplify positioning, with best results when used with an adhesive barrier solution and applied before bed.
• Stretch and Comfort: Four-way stretch helps the patch move with the body so it stays comfortable during everyday activity and exercise.

Who It's For

This patch is a good match for people using Dexcom G7 or Stelo sensors who want extra protection against water and sweat and who aim to keep a sensor in place through daily activity and intermittent swimming. It suits active adults and athletes who need a breathable, hypoallergenic option that reduces sensor changes.

Those who frequently need a very firm adhesive in oily or highly abrasive environments, or users who prefer an unbroken adhesive ring rather than a split five-piece design, may want to test one patch first or look at alternatives focused entirely on maximum edge adhesion.

Pros & Cons

Pros

• Waterproof adhesive that protects the sensor in showers and swims when dried afterward.
• Comfortable, skin-friendly composition reduces irritation during long wear.
• Pre-cut, split design simplifies application and helps align the sensor reliably.
• Four-way stretch keeps the patch flexible and comfortable during activity.

Cons

• Some users report mixed stickiness and occasional edge lifting after a day or two, so results can vary by skin type and activity.
• A minor number of customers noted fraying around edges after extended wear in demanding conditions.

Our Verdict

These purple patches are a strong option for CGM users who want a waterproof, comfortable overpatch that extends sensor wear and tolerates active days. They offer good value for people who prioritize breathability and hypoallergenic materials, though users with very oily skin or extreme abrasion may see variable adhesion and should try a single patch first.
