Collection: Fitbit Sense Bands

No. The Sense 2 pairs with the Fitbit Versa 4 and uses a different locking attachment, so its bands will not seat in the original Sense. The Sense shares its fitting with the Versa 3 instead, which is why bands here are labelled for both. Our Fitbit Sense 2 bands collection covers the newer watch.

Check the device name in the Fitbit app, since the two look almost identical from the front. The quickest physical check is the band: if a Versa 3 strap clips in, you have the original Sense. The Sense 2 is slightly thinner and lighter, and takes the same bands as the Versa 4.

Silicone or the sports loop. The Sense tracks sleep and overnight skin temperature, so it stays on through the night, and a soft strap with no metal against the wrist is easier to sleep in. The sports loop closes with velcro, so it can be slackened at bedtime and tightened again in the morning.

Yes, more than the material does. A band that slides around loosely lets the sensor lose contact with the skin, while one worn too tight is uncomfortable over a full day. Aim for snug with a little movement. Milanese and the sports loop adjust anywhere along their length, which makes fine-tuning easier than fixed holes.

Both are silicone and sit at the same price. The AirVent is perforated along its length so air moves across the skin, which suits sweaty workouts and warmer weather. The standard strap is solid silicone, smoother against the wrist and easier to wipe clean. Either clips into the Sense the same way.
