HydroKnit Nylon Sport Band Compatible with Whoop 4.0 | Soft, Elastic, Fast-Drying, Water-Resistant, and Comfortable Replacement Strap for Active Lifestyles

Great price and product. Looks the same as Whoop band that came with the Whoop.

Band Looks good and fits my Whoop. The one side that clips onto the trap doesn't stay in place perfectly so the strap has fallen off once. could be that I just have to press it in a little harder to get it to click in properly. Over all I am happy with my purchase though and enjoy the quick dry fabric. It also shipped quickly.

I got the whoop, but didn't really care for the band. Especially while wet. So I'm trying this out. Replacing the band on the device is really easy, didn't need instructions, heck didn't see any. It came with a qr code on the package, so that might have been the instructions. But the package was in Chinese of course so who knows, I didn't try. I opted to try wearing it on my ankle, showering bothered me less during and after as opposed to the original band. And I went for a very long walk, an hour and 17 minutes, and wasn't too bothered with it on my ankle, though it did feel a bit tight. I have loosened it, and slept with it. I don't think I like this one much more than the original, but it was easy to put on.

My reviews for this one item isn’t saving…It’s a comfortable band but has a few small issues that made me take away stars;• J hook and bracket that go on whoop are flimsy and are very loose. They come off often when I remove the whoop, but stay on when properly secured.• Strap is cut at a diagonal, has 2 sharp corners which can be felt when you move your wrist: solution is to to tuck extra material under the corner of the whoop bracket.

The sports band seems to have hardware like 'Whoop', though the fabric is more nylon than the sports fabric used by Whoop. While it is significantly less expensive, the battery does not easily fit over it (precision of metal components), making it difficult to charge.

Fits my Whoop 4.0 perfectly. It is made of quality material. The value for the material is great and easy to adjust and comfortable to wear.

Pros:Soft, elastic fabric feels comfortable during long wear.Fast-drying material handles sweat and water exposure well.Band adjusts easily for a secure and customized fit.Minimal design pairs well with casual or workout outfits.Durable stitching holds up to frequent stretching and movement.Cons:Band edges fray slightly with heavy use.Elastic loosens a bit faster than expected.Attachment to device feels less secure than official bands.Color fades slightly with exposure to sun and chlorine.Adjustment slider can shift during intense workouts.

Works for my whoop just fine
