Griffin Technology - Sleep Sport Band for Select Fitness Trackers - Black

This is a very comfortable band to hold my Fitbit One. I use it on my ankle and wrist and have not had a need to use the extension band it comes with. Great fit, comfortable and less bulky than the one I have from Fitbit. The only complaint, which is the same one I have with the Fitbit band, the cover is a mesh material, so sometimes I can't make out certain numbers. Otherwise, this band is awesome! I haven't experienced the velcro losing its holding power as some have already experienced and I use this everyday and have had this for five weeks. I have to admit that I use the original Fitbit band when I am spinning because of the amount of sweat and don't want to ruin the Griffin band....yet. If it does get ruined, I will probably purchase the Griffin band again!

I bought fitbit one and it comes with a sleep band and I found the fitbit would fall out sometimes because it goes in from the top and it is wide, this one loads from underneath and is not very wide, lot more comfortable

Like to wear device on my ankle, lost one misfit with the magnetic clip that was supplied in box The band offers greater security for th device, band is comfortable you do not realize you are wearing. Can be worn on wrist or arm band is adjustable and will work for men.

I found that the original sleep band that came with the FitBit One inadequate. The Griffin stays in place much better and holds the FitBit securely. The quality of the Velcro could be better, but otherwise a good product.

I've had a fitbit one for a couple years now and been through two of the sleep bands that came with it. The Velcro gets gunked up and they start falling off during the night. I like this one much better. It's slimmer on your wrist (more like a watch) and the tracker fits in more securely AND the Velcro still works well. Great product!

I use this with my fitbit one and fitbit alta. I have very sensitive skin, it is a great alternative to the watch style fitness trackers that irritate my skin. The only drawback is, the velcro does not hold up to repeated hand washing for more than 2 months.

Holds Fitbit in pocket on the band. Easy to use and very comfortable. Allows you to see screen through the material without having to remove Fitbit from band.

This band s very comfortable to wear when sleeping. I purchased a second one because the first one is getting a bit stretched out. It is still wearable, but I keep it for a back-up or for use when traveling.
