The Rep stretch nylon band for WHOOP 5.0, 4.0 and 3.0

What the Rep is

The Rep is a loop of soft, stretchy woven nylon made for WHOOP sensors. It holds the sensor with a black slider and a black clasp that are part of the band itself, the same slider-and-clasp setup WHOOP uses on its own bands. Your sensor slides in, the clasp hooks over it, and that is the whole setup.

That is what the "NO Frame" label on the color photos means. Many WHOOP bands from other makers hold the sensor in a separate metal frame that clips around it. The Rep doesn't need one, so there is no frame to fit, no extra part to lose and nothing else to buy. The band and your sensor are all you need.

The nylon is woven to stretch, so the band gives a little as your wrist flexes and stays soft against your skin through long days, workouts and nights. The open weave lets air through, and the band is light on the wrist.

The Rep comes in nine colors: Black, White, Denim Blue, Charcoal, Olive, Indigo, Stone, Midnight Blue and Starlight. Charcoal is made for the WHOOP 4.0 and 3.0 sliders only; the other eight colors come in all three versions.

Choose the version for your sensor

WHOOP has changed the size of its sensor between generations, and the slider has to match the sensor it holds. That is why the Rep is made in three versions, and why you choose WHOOP 5.0, WHOOP 4.0 or WHOOP 3.0 under Sensor before you order.

• WHOOP 5.0: the slider for the 5.0 sensor, which is smaller than the 4.0.
• WHOOP 4.0: the slider for the larger 4.0 sensor.
• WHOOP 3.0: the slider for the earlier 3.0 sensor.

The versions are not interchangeable. WHOOP itself says its 4.0 bands don't fit the 5.0 and MG sensors, because the newer sensors are smaller, and the same goes for the Rep: a version made for one generation won't hold another generation's sensor securely.

The Rep is listed for WHOOP 5.0, 4.0 and 3.0. If you wear a WHOOP MG, choose one of the bands listed for MG on our WHOOP bands page.

How to put it on and size it

Slide your sensor into the black slider on the band. Wrap the band around your wrist with the sensor on top, then hook the black clasp over the sensor to close the loop. To change bands, unhook the clasp and slide the sensor out. No tools needed.

One size fits wrists 5.9 to 8.7 in (150 to 220 mm), with about 1.2 in (30 mm) of stretch in the weave. If you're not sure where your wrist falls in that range, our fit guide shows how to measure it.

Wear it snug but not tight. The sensor should sit flat on top of your wrist without sliding around, and the band shouldn't leave deep marks. The stretch makes that easy to get right, since the band gives a little when you flex your wrist or grip a bar.

Care

Take the sensor out before you wash the band. Hand wash it in warm water with a little mild soap, rinse well, press the water out with a towel and let it air dry flat. Skip the washing machine and the dryer, as heat is hard on the stretch in the weave.

Nylon handles sweat, rain and showers, but it holds water longer than silicone. Rinse it in fresh water after salt water or a pool. If you train most days, two bands in rotation let one dry while you wear the other.
