Review on SKYLET Fitbit Ionic Bands For Men With Case - Soft Replacement Sport Wristband Compatible With Fitbit Ionic Smart Watch With Metal Clasp For Men And Women - Black (Tracker Not Included) by Eric Webb

Not sure what secondary rubber compound is on this protective case / band for the Iconic, but it prevents slipping so I can wear a little looser than normal. This is probably the smallest profile case / band combo you'll find. The only negative I would give this case is where the band and case meet, depending on your activities you could get some dust / small dirt particles up under the rubberized casing.
