If you’re weighing screenless fitness tracker strap options before you buy, the honest answer is: most REXQU screenless bands come in one fixed strap, but one model breaks that pattern on purpose.
Quick answer: the REXQU AeroBand is the only screenless fitness tracker in REXQU’s current lineup with a swappable strap — silicone or nylon, in four colors (Black, Blue, Orange, Pink). GuardBand, CardioBand and PulseBand ship with one fixed band and no listed alternate material or color. See the full lineup on the REXQU screenless fitness tracker collection.
Screenless Fitness Tracker Strap Options by Model
Strap choice matters for two practical reasons: comfort against your skin during long wear, and whether the band matches your day-to-day style. Here’s what REXQU actually lists for each screenless model.
| Model | Strap Material | Color Choices | Design |
|---|---|---|---|
| AeroBand | Silicone or Nylon (your choice) | Black, Blue, Orange, Pink | Zinc-alloy double-bar, wears like a piece of jewelry |
| GuardBand | Fixed (silicone-style band, no listed alternate) | Not listed as a customer choice | Featherweight safety-focused build |
| CardioBand | Fixed (silicone-style band, no listed alternate) | Not listed as a customer choice | Slim ECG-focused build |
| PulseBand | Fixed (silicone-style band, no listed alternate) | Not listed as a customer choice | Wellness/ECG-focused build |
Only AeroBand exposes strap material and color as an actual purchase option. That’s a meaningful screenless fitness tracker strap options difference if fit, feel, or matching an outfit matters to you as much as the health tracking underneath.
Silicone vs. Nylon: Which Should You Pick?
Silicone is the default material on most fitness wearables. It’s fully waterproof, wipes clean easily, and holds up well to sweat, sunscreen and chlorine. The trade-off is that it doesn’t breathe, so it can trap moisture against skin during long workouts or hot weather — and for a small share of wearers, prolonged contact with synthetic band materials can contribute to skin irritation. The NCBI’s overview of contact dermatitis explains that irritant reactions to everyday materials are more common than most people expect, which is part of why some wearers prefer switching strap materials rather than sticking with whatever ships in the box.
Nylon straps trade a little water resistance for breathability. They’re woven, so air moves through them, which tends to feel cooler over a full day of wear and dries out faster after a sweaty session. If you’ve had any skin sensitivity to silicone bands before, AeroBand’s nylon option is worth trying first.
Why AeroBand Offers a Choice and the Others Don’t
AeroBand is REXQU’s simplest screenless tracker — 24-hour heart rate, blood pressure, blood oxygen, and sleep tracking without the ECG or safety-alert hardware built into CardioBand, GuardBand or PulseBand. That simpler internal build appears to leave room for AeroBand to be sold as a lifestyle accessory as much as a health tracker, which likely explains why REXQU lists it with genuine strap and color variations while the more feature-dense models stick to one configuration.
If ECG recording, GPS safety alerts, or maximum battery life matter more to you than strap choice, CardioBand, GuardBand, and PulseBand remain strong picks — you’re simply committing to their single stock band.
How to Choose Based on Strap Options Alone
- Pick AeroBand if you want to match the band to your wardrobe, switch between silicone for workouts and nylon for daily wear, or you’ve reacted to synthetic bands in the past and want a breathable backup.
- Pick GuardBand if GPS-based safety tracking and fall detection matter more than strap flexibility.
- Pick CardioBand if on-demand ECG recording is the priority.
- Pick PulseBand if you want the longest battery life alongside broad wellness tracking.
Whichever model you choose, all four screenless trackers pair with the same free REXQU app over Bluetooth, so day-to-day use feels consistent even though the hardware and strap flexibility differ.
Frequently Asked Questions
Can I buy a replacement strap for AeroBand separately?
REXQU lists silicone and nylon as selectable options at checkout on the AeroBand product page, rather than as a separate after-market accessory purchase.
Will a different strap change the tracking accuracy?
No — the sensors sit in the housing on the underside of the band, not in the strap material itself, so switching between silicone and nylon shouldn’t affect heart rate, SpO2, or blood pressure readings.
Is nylon less water-resistant than silicone?
Woven nylon can absorb more moisture than solid silicone, though AeroBand’s 1ATM water resistance rating covers rain, sweat and hand-washing regardless of which strap you choose.
Bottom line: if screenless fitness tracker strap options are part of your decision — not just the health metrics underneath — AeroBand is currently the only REXQU model built to let you choose. Compare it against the rest of the range on the REXQU screenless fitness tracker collection page.
