Nylon Sport Loop Wristband Compatible with Whoop 4.0 for Women Men, Soft Adjustable Breathable Replacement Bands for Whoop 3.0/4.0 Durable Sleep, Wearable Health, Fitness & Activity Tracker

Okay, I really like these wristbands! They work a bit differently than your standard Whoop band, and have two primary differences that I feel make them the best option for stomach and side sleepers who tend to put their hands under their pillows as they sleep.First, the Whoop itself snaps into a hard plastic covering case, versus using the more finicky process of sliding into two clips and then snapping a clip on top of the Whoop, like a standard Whoop band. This means that you reduce the chance of accidentally unsnapping the clip & losing your Whoop just from moving in your sleep, which I have done more than a few times.The band is adjustable and secured with velcro, and is not particularly elastic. This means that you can set up a fit and not have to worry about the band loosening or traveling all over your wrist as you sleep. For me, a standard Whoop band would migrate during the night and get twisted or tighter and cut off circulation or put pressure on my wrist, causing me to wake up. The Y-Kocos design does NOT come with this issue, meaning I slept much better as I was not constantly waking up to wrist pain or discomfort. The band simply stayed put all night.The one downside is that this does NOT dry quickly; make sure you fully take off the band when washing your hands, cooking, etc. I got this band wet and had to blowdry it as it doesn't air-dry like other Whoop bands.But for me, being able to sleep without the Whoop band popping open or cutting off circulation solves my biggest issue with my Whoop, so these bands are very much worth it in my opinion!!

Not what I expected and it doesn't have a hook. It works for a temporary fix but not without wrangling. Thankfully the charger fits over the protective case and allows charging while wearing, I was doubtful about that at first. Otherwise, it feels comfortable.

Cool band, nice sleek design, not really that bulky but bulkier than the OG band… now the issues with it, so far after having it for several days is that the fact the plastic covers the top poses a issue with how the tracker charges, it needs a certain amount of resistance away from the buck and the sensor but the plastic slows down or completely stops charging at times. THIS MAY JUST BE ME, I’ll still be using it as I appreciate the design and ease of adjustment but you need to charge it in the original band :/

You get what you pay for. Poor quality. Functional if that’s what you need.

These were scratchy and gross. I returned immediately.

The sensor sits well in the plastic casing. The bands are a little bulkier than the original, but still soft and comfortable. No issues at all with the charging pack sliding right over the top just the same as the original. I like the bright orange best!

It’s cheap not a good quality but it works

Love if, one thing they can improve is charging with this band is not possible
