surundo Nylon Sport Band Compatible with Whoop Band 4.0 Strap Men Women with Bumper Case, Breathable Nylon Adjustable Waterproof Replacement Wristbands Straps for Whoop 4.0

So easy to use, love the variety of colors and fits Charge 6 perfectly

Very nice band for my whoop. So much less expensive than than ordering it from the Whoop website

The darker colors are fine, but the lighter ones seem to pick up color transfers—I wear a lot of dark colors and the fabric seems to leave smudges on the strap that won’t come off, as you can see on the strap loop in my picture. It just looks grimy now and I won’t wear the lighter ones because of this. I’ve never had this problem with the many kinds of rubber replacement bands I’ve bought over the years and it’s a small thing but I’m disappointed.

The bands were exactly what I expected. Easy to put on and the colors are good. Love the double clasp.They also are very flexible and comfortable.

These colors are really nice. I like how many different options come in the one package. They are easy to attach/detach from my Fitbit and stay on once they are attached. They are comfortable and breathable. It's winter now, so can't say if they'll make you sweaty in the heat, but during workouts they have not caused sweat issues.

The clasp where you slide the whoop into the frame is too open for it to fit. It slides on, but slides off immediately. Not well made.

Nice band, nothing fancy, but made out of a material that I can keep on for swimming and showering. Good value. Initially I was concerned because it doesn't have a standard type buckle, but haven't had any trouble with them in several months. Fun to change out colors

Good-looking band, but small for a man's wrist. It does fit, just barely, and my wrists are not large. A tight fit for sure.
