Yes! Both the Comfort-Fit and the Active-Fit Bands are compatible with JrTrack 1, 2 and 2 SE.
Comfort-Fit bands are made with a soft Synthetic Fabric, and are secured with Velcro. Active-Fit bands are made of premium silicone, and have a buckle and tuck-away design.
We’ve linked a video above on how to change the bands. You can use a paperclip or pencil to push the pins in on the Active fit, or use the built-in handle lever on the Comfort-Fit.
