Lexcam vs Not Just a Patch: Which Dexcom G7 & Stelo Patch Is Actually Better?

If you’ve ever typed “best patches for Dexcom” into Google, you’ve probably seen two names pop up over and over: Lexcam and Not Just a Patch (NJAP for short). Both have loyal followings. Both promise to keep your CGM stuck on through showers, sweat, and general life chaos.

Here’s the honest breakdown, because I know you just want your sensor to stay put without turning your skin into a peeling mess.

What makes Not Just a Patch different (and where it falls short)

Let me give NJAP credit where it’s due – they came up with a clever idea. The middle section of their patch doesn’t stick to the sensor at all. It only grabs your skin around it. That means you can peel off the overpatch mid-session without accidentally ripping out your sensor. Pretty smart, right?

And the wave pattern design? Breathable, looks decent, and they use medical-grade adhesive. For someone who wants to change their patch every few days, NJAP is a reasonable option.

But here’s the catch: the adhesive NJAP just isn’t that strong. It holds up fine if you live a mostly sedentary life – desk job, light walking, quick showers. But the moment you start sweating for real? Working out? Swimming? The edges start lifting way before the 10-day mark. I’ve had NJAP patches curl up on day four after a simple jog. And waterproof? They say water-resistant, but in my experience, a long hot shower is enough to make them peel.

Why Lexcam is the better choice for most people (especially if you’re active)

Now let’s talk about Lexcam. I’ll be upfront – I’ve used them for months and they’ve never let me down.

• Strong adhesive that actually lasts. Lexcam patches have serious grip. We’re talking the kind of adhesive that laughs at sweat, humidity, and accidental bumps against doorframes. I’ve worn one through a full 14-day sensor session – hot yoga, beach swimming, daily showers, and a few very sweaty hikes – and the edges stayed completely flat the entire time. No lifting, no peeling, no stress.
• Truly waterproof. Not “water-resistant.” Waterproof. I’ve jumped into pools with a Lexcam patch on my Dexcom G7. I’ve stood under scorching hot showers for twenty minutes. The sensor stayed dry, the patch didn’t budge. If you swim, surf, or just refuse to take military-speed showers, this matters.
• Perfect for active people and athletes. This is where Lexcam separates from NJAP. If you run, cycle, lift weights, do CrossFit, or just live a life that involves regular sweat – Lexcam is built for you. The adhesive is engineered to handle movement and moisture without failing. I can’t say the same for NJAP, which always felt like it was about to give up during my morning run.
• Honest note about removal. Let me be real – because the adhesive is so strong, Lexcam patches can be a little trickier to remove than some weaker brands. But that’s not a flaw; it’s proof they’re doing their job. That serious sticking power is exactly what protects your sensor from falling off mid-swim or mid-workout. And here’s the easy fix: a little baby oil or an alcohol wipe helps loosen the adhesive, and the patch comes right off without damaging your skin. No pain, no sticky residue. Just a clean removal.
• Invisible and pre-cut. Lexcam patches are transparent, so they blend right into your skin. And they come pre-cut specifically for Dexcom G7 and Stelo – no scissors, no fuss, just peel and stick.

So which one should you buy?

Look, if you really need to swap patches mid-session for some reason – maybe you like changing colors or you messed up the first application – Not Just a Patch might make sense. That peel-off feature is genuinely useful for a small group of people.

But for everyone else? - Lexcam.

Stronger adhesive. Actually waterproof. Perfect for athletes, runners, swimmers, and anyone who doesn’t want to think about their CGM patch after they put it on. It stays stuck, it protects your sensor, and it doesn’t irritate your skin.

I’ve tried both, and I keep coming back to Lexcam because it just works. No peeling edges on day three. No worrying about a swim. No waking up to a dangling sensor.

If you want the best patch for Dexcom G7 or Stelo – especially if you’re active – Lexcam is the answer.
