I was wearing original style straps for my Fitbit 3 charger until I came across these. They are so much more comfortable to wear. 1 v They have holes for air access, 2 v. these are soft ligaments and 3 BC. You don't have the part where the extra tape goes through when you tighten it. This species slips through the gap and invades itself. I will never buy any other kind again.
