Made obsolete within a few weeks...
on August 7, 2025
Posted by: Nicholas H
Seemed pretty good. Nice design, felt good to wear and didn't remain soggy after the shower like the original.
Unfortunately, I only had the band for a matter of weeks before Whoop 5.0 was released and made this obsolete. It's now useless as it doesn't fit the new slimmer design.

Comfortable with exceptions…

The whoop blur band is as comfortable as the mesh versions. The band lacks the almost infinite adjustment of the basic band , and the latching mechanism is troublesome to install. I still have problems with the promenant device catching when I put on my coat.

Loving the new band!

I have a few whoop bands that absorb water & sweat, as I’m active I would have to keep taking them off, washing them & rotating between them daily. New band is rubber which is perfect for me!

fit

Great overall, but the strap came loose and nearly fell off while I was on the metro — needs a more secure fit.

Sports flex band 4.0
on July 31, 2025
Posted by: Kelly H
Hi there,
I am writing to communicate what I believe is a fault in the product I have received / bought. I bought my husband a sport flex 4.0 band for his whoop but it simply just does not remain fastened and keeps coming undone. He is a triathlete and this therefore is not conducive to be warn during training or otherwise to be honest.

I would be interested to know if you are aware of this fault in design, if others have complained or indeed if you feel this is purely just a fault of this one band?
This is a great shame as he likes the comfort and look of the band.
I look forward to hearing from you promptly.
Thanks,
Kelly Higgins

Nice band but now I've upgraded to the MG it was just an expensive waste of money

This is a good band for wearing when doing sports - running, swimming, cycling, it's comfortable and doesn't mind a bit of sweat.
But then Whoop brought out the 5/MG device, which I upgraded to, and existing bands are no longer compatible with it due to the tiniest of changes in the new design.
Maybe Whoop will bring out an adapter to make the older straps work with the newer ones, but right now it's just sat on my windowsill, where it's been consigned to until I get round to selling it on Vinted.

Not great. Gave me a rash
on July 7, 2025

I bought this so I could swim with it. I have never been allergic to silicon or anything similar but this band gave me a rash after a week of wearing that took weeks to heal fully. Wasted purchase.

Good fit but causes skin irritation
on July 7, 2025
Posted by: Margot E
Unfortunately the band caused my skin to go get very itchy and blistery. I am not at all prone to allergies and sensitivities so there might be something in this band that causes a problem. The band is a great fit and easy to put on and off, but I simply can't use it and have had to go back to the original band supplied by Whoop, which is disappointing, not to mention the cost of the band which I cannot use.
