Just needed to replace my old Fitbit 3 with a Charge 4. The good news is that any straps you bought for the Charge 3 will fit your Charge 4. Thank God. I'm always looking for a super light, breathable harness. This set is great. I chose white/grey and black. They have a velcro-like hook/loop that you can easily push and pull to release. The material has a slight stretch which makes it more comfortable. So far this is one of my favorite types of groups. They had better printing options, but it's a bit like a woven ribbon, which can limit choices. Either way, I'd rather have comfort than those footprints. You can adjust the bracelet to fit your wrist exactly how you want it. I like mine slightly loose. No problem as there are no holes that you NEED to go in that may not be just right. Looks and feels like it will last a while too. Despite this, I never hesitate to update my reviews when new information seems useful.
