Do these straps fit the Polar Unite?

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

Do these straps fit the Polar Vantage or Grit X?

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

How do I change the strap on my Unite?

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

What width strap does the Polar Unite use?

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

Which strap 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 strap on hand to cover both.

Can I wear these straps in the shower?

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