Choosing a replacement band for a COROS watch starts with one thing:
the correct size.
COROS uses several band widths across its PACE, APEX, NOMAD and VERTIX families, including 20mm, 22mm, 24mm and 26mm.
That means two COROS watches can look similar while requiring completely different straps.
Buying according to brand alone is not enough.
You need to identify your exact watch model, confirm its required band width and check whether it uses a quick-release or compatible attachment system.
This guide makes that process easier.
What Size Band Does My COROS Watch Need?
The correct COROS band size depends on your exact model.
Several popular COROS watches fall into different width groups.
A simplified compatibility overview looks like this:
20mm
- COROS PACE 2
- COROS APEX 42
- COROS APEX 2
22mm
- COROS PACE 3
- COROS PACE Pro
- COROS PACE 4
- COROS APEX 2 Pro
- Selected APEX models
24mm
- COROS NOMAD
- Selected newer APEX configurations
26mm
- COROS VERTIX 2
- COROS VERTIX 2S
However, you should always confirm the exact model and attachment type before purchasing.
The width is only one part of compatibility.
COROS 20mm Watch Bands
A 20mm COROS band is used by several smaller or lighter COROS models.
Popular examples include the PACE 2 and APEX 2.
These watches use a relatively narrow strap width, which helps maintain a lightweight profile suitable for running and endurance training.
COROS PACE 2 Band Size
The COROS PACE 2 uses a 20mm quick-release band.
That makes 20mm one of the key replacement sizes for runners still using the PACE 2.
A replacement band can be useful when:
- Your original strap is worn
- You want a different material
- You want a lighter nylon option
- You want another color
- You need a second band for training
Nylon and silicone are both popular choices depending on how you use the watch.
COROS APEX 2 Band Size
The COROS APEX 2 also uses a 20mm quick-release strap.
This means shoppers looking for an APEX 2 replacement should focus on compatible 20mm options rather than assuming all APEX watches use the same width.
This distinction matters because the APEX 2 Pro uses a different size.
COROS 22mm Watch Bands
The 22mm COROS band category covers several important models.
This includes watches such as:
- COROS PACE 3
- COROS PACE Pro
- COROS APEX 2 Pro
- Selected APEX models
Because these watches are commonly used for running, endurance training and outdoor activities, 22mm replacement straps are available in several sport-oriented materials.
COROS PACE 3 Band Size
The COROS PACE 3 uses a 22mm quick-release band.
This is important because the previous PACE 2 uses 20mm.
Do not assume that a PACE 2 band will fit a PACE 3 simply because both watches belong to the same family.
If you own a PACE 3, look specifically for compatible 22mm options.
Good PACE 3 Band Materials
Depending on your activity, you can consider:
- Nylon
- Silicone
- Woven fabric
- Elastic-style straps
For running, many users prefer lightweight and easily adjustable designs.
For everyday wear, you may want a more neutral color or cleaner appearance.
COROS PACE Pro Band Size
The COROS PACE Pro also uses 22mm quick-release bands.
That places it in the same broad width category as the PACE 3.
COROS states that PACE 3 and APEX 2 Pro bands can be compatible with PACE Pro, although some form-fitting silicone bands may be designed specifically around the watch body.
This is why checking the exact product design is still important.
A generic 22mm width does not always guarantee the same visual fit around the case.
COROS APEX 2 Pro Band Size
The COROS APEX 2 Pro uses a 22mm band, while the standard APEX 2 uses 20mm.
This is one of the easiest compatibility mistakes to make.
The model names are very similar:
APEX 2 → 20mm
APEX 2 Pro → 22mm
Always verify whether you own the standard or Pro version before purchasing a replacement strap.
COROS 24mm Watch Bands
Some newer COROS models use a wider 24mm quick-release band.
The most notable example is COROS NOMAD.
COROS NOMAD Band Size
COROS NOMAD uses a 24mm quick-release strap.
Because 24mm sits between the more common 22mm and 26mm formats, it is particularly important not to estimate the width visually.
A 22mm band will not become compatible simply because the difference looks small.
Likewise, a 26mm strap is too wide.
Choose a replacement specifically designed around the correct 24mm connection.
COROS 26mm Watch Bands
The largest common COROS band size is 26mm.
This format is associated with larger outdoor watches such as the VERTIX line.
COROS VERTIX 2 Band Size
COROS VERTIX 2 uses a 26mm band.
The larger strap visually suits the substantial case and outdoor-oriented design of the watch.
Replacement options can include:
- Nylon
- Silicone
- Rugged sport straps
- Outdoor-focused designs
COROS VERTIX 2S Band Size
COROS VERTIX 2S also uses 26mm bands.
COROS specifically offers both nylon and silicone options for this watch.
For long outdoor activities, strap comfort can become particularly important because the device may be worn for many hours at a time.
COROS 20mm vs 22mm vs 24mm vs 26mm
These numbers refer to the width of the band attachment.
They are not wrist sizes.
A person with a large wrist can own a watch using a 20mm band.
A person with a smaller wrist can wear a watch using a 26mm band.
The band width is determined by the watch.
Your wrist circumference determines whether the actual strap length fits comfortably.
That means you should check two things:
1. Watch compatibility
20mm, 22mm, 24mm or 26mm.
2. Wrist fit
Whether the strap itself can adjust comfortably around your wrist.
Do not confuse the two.
Quick Release vs Quick Fit on COROS Watches
Another important detail is the attachment system.
Most modern COROS models use some form of quick-release mechanism, but not every COROS generation uses exactly the same system.
For example, current COROS compatibility information distinguishes between quick-release and other attachment formats across different models.
This means:
Band width alone is not enough.
A compatible replacement should match:
- The exact watch model
- Band width
- Attachment mechanism
Always check all three before ordering.
Nylon vs Silicone COROS Bands
Once you know the correct size, material becomes the next decision.
Both nylon and silicone can work well for COROS watches, but they feel very different.
COROS Nylon Bands
A COROS nylon band can be a strong choice for runners and users who prioritize lightweight comfort.
Nylon straps are commonly chosen for:
- Running
- Trail running
- Hiking
- Long training sessions
- Travel
- Everyday wear
A woven band can also offer very fine adjustment.
This is useful when you want the watch to sit securely during training without feeling unnecessarily tight.
COROS Silicone Bands
Silicone is another natural choice for sports watches.
A COROS silicone replacement band can work particularly well for:
- Running
- Gym sessions
- Cardio
- Outdoor activities
- Daily training
- General fitness
Silicone is smooth, flexible and typically easy to wipe down after a workout.
For athletes who sweat heavily or train frequently, this can be especially convenient.
Nylon vs Silicone for Running
For running, the better material depends largely on personal preference.
Choose Nylon If You Prefer:
- Lightweight feel
- Flexible adjustment
- Woven texture
- Softer wrist contact
- Minimal bulk
Choose Silicone If You Prefer:
- Smooth surface
- Sport-oriented feel
- Easy wipe-down
- Traditional sports-watch appearance
- Flexible construction
There is no universal winner.
A lot depends on how the strap feels on your wrist over longer runs.

Best COROS Band for Running
A good running band should feel stable without being restrictive.
Look for:
- Low weight
- Secure fit
- Easy adjustment
- Flexible material
- Minimal movement
- Comfortable skin contact
Nylon and flexible silicone are both strong categories to consider.
The watch should remain stable enough for comfortable training while avoiding excessive pressure.
Best COROS Band for Trail Running
Trail running introduces additional movement, weather exposure and longer sessions.
Useful strap characteristics include:
- Secure attachment
- Comfortable long-duration fit
- Lightweight construction
- Adjustable closure
- Easy maintenance
A woven nylon or flexible sport strap can be practical for long days on the trail.
Best COROS Band for Hiking
Hiking often means wearing your watch continuously for several hours.
Comfort becomes especially important.
For hiking, consider:
- Breathability
- Adjustability
- Weight
- Durability
- Secure attachment
- Easy cleaning
Nylon is a popular choice for users who like a lighter strap.
Silicone remains practical if you want something easy to wipe down after dusty or sweaty conditions.
Best COROS Band for the Gym
Gym sessions can involve repeated changes in wrist angle.
Think about movements such as:
- Bench press
- Pull-ups
- Rows
- Dumbbell curls
- Kettlebell exercises
- Cable work
- Push-ups
A flexible band is generally more comfortable than an overly rigid design.
Both nylon and silicone can be suitable.
Best COROS Band for Everyday Wear
Your COROS watch does not need to look exclusively like a training device.
Changing the band can alter the entire appearance of the watch.
For everyday use, consider:
- Black nylon
- Navy nylon
- Neutral silicone
- Woven bands
- Elastic straps
- More refined designs where compatible
Black, gray and navy are easy to match with most clothing.
Brighter colors can turn the watch into a stronger visual accessory.
COROS Bands for Work and Travel
If you wear your COROS throughout the day, you may want a strap that looks less sport-specific.
A clean woven or neutral band can make a sports watch easier to pair with casual or work clothing.
For travel, comfort becomes even more important.
A lightweight band can be useful when wearing the watch for:
- Flights
- Walking tours
- Hiking
- Commuting
- Sleep tracking
- Long days outdoors
Owning more than one replacement band can make it easier to switch between these uses.
Can You Change a COROS Band Yourself?
Many newer COROS watches use quick-release bands designed to make changes straightforward.
The general process is:
- Place the watch on a clean surface.
- Locate the quick-release lever on the back of the band.
- Pull or slide the lever to retract the spring bar.
- Remove the existing strap.
- Position the replacement band between the watch lugs.
- Retract the spring bar.
- Release it once aligned.
- Confirm that the strap is securely attached.
The exact procedure can differ by model.
Always follow the instructions for your specific COROS watch.
How Tight Should a COROS Watch Band Be?
Your strap should be secure enough to prevent excessive movement but not so tight that it becomes uncomfortable.
This balance is especially important during running.
A watch moving excessively on the wrist can be distracting.
An overly tight strap may become uncomfortable during longer sessions.
You may also want slightly different adjustments for:
- Running
- Everyday wear
- Sleep
- Gym training
- Hiking
This is one reason adjustable nylon bands are popular among endurance athletes.
Can I Use Third-Party Bands With COROS?
Some COROS watches can work with compatible third-party quick-release bands.
However, compatibility should always be verified for the exact watch model.
Check:
- Width
- Attachment system
- Spring-bar design
- Fit around the watch case
- Wrist-size range
A strap that is technically the correct width can still have a different shape or fit around the watch body.
Always review the specific product compatibility information before buying.
Common COROS Band Buying Mistakes
Buying by Brand Only
Not all COROS watches use the same band.
Confusing PACE 2 and PACE 3
PACE 2 uses 20mm.
PACE 3 uses 22mm.
This is a major difference.
Confusing APEX 2 and APEX 2 Pro
APEX 2 uses 20mm.
APEX 2 Pro uses 22mm.
Assuming Width Means Wrist Size
20mm and 22mm describe the band connection width, not wrist circumference.
Buying a 22mm Strap for NOMAD
COROS NOMAD uses a 24mm band.
Buying a 22mm Band for VERTIX 2
VERTIX 2 and VERTIX 2S use 26mm bands.
Ignoring the Attachment Type
Always verify both width and connector system.

Find the Right COROS Replacement Band
Choosing a COROS replacement strap becomes simple once you follow the right order.
First, identify your exact COROS model.
Then determine whether it requires:
20mm
22mm
24mm
or
26mm
Next, verify the attachment system.
Only after compatibility is confirmed should you choose between nylon, silicone, woven or another available material.
As a quick reference:
PACE 2 / APEX 2 → 20mm
PACE 3 / PACE Pro / APEX 2 Pro → 22mm
NOMAD → 24mm
VERTIX 2 / VERTIX 2S → 26mm
Once you know your size, choosing a replacement strap becomes much easier.
You can then build the setup around what actually matters to you: running, trail training, outdoor adventures, everyday comfort or simply changing the appearance of your COROS watch.
