Do these bands fit the Polar Unite?

Yes. The Polar Unite uses a 20mm quick-release band, and any style on this page fits it directly. Polar has kept this width consistent since the Unite launched in 2020.

Do these bands fit the Polar Vantage or Grit X?

No. Both the Vantage and Grit X families use a wider 22mm band, a different width from the Unite's 20mm.

How do I change the band on my Unite?

Push the small lever on the spring bar behind the band to release it, then press the new band's spring bar into the lugs until it clicks. It takes under a minute with no tools.

What width band does the Polar Unite use?

20mm. It's the same width as the Polar Ignite and the standard Pacer, so bands are interchangeable across those three watches.

Which band is best for sleep tracking?

The Véllo nylon loop is the practical pick for overnight wear, since it's soft, breathable and comfortable enough not to notice while you sleep. Owners who track both workouts and sleep with the same watch often keep both a nylon and a silicone band on hand to cover both.

Can I wear these bands in the shower?

Silicone and nylon bands handle everyday water exposure fine — rinse and dry them afterward. Wipe magnetic milanese or magnetic loop bands dry instead of soaking them. Avoid machine-washing any band material, since the clasp hardware isn't designed for it.
