BLAYKE Premium SportFlex Wrist Band - Soft-Touch Silicone, Waterproof, Sweatproof, Compatible with WHOOP 4.0

I loved this Sportflex Strap! It’s super lightweight and feels great on my wrist. The silicone material is high-quality, long-lasting, and comfortable, even during intense workouts. I’ve tried multiple other brands, but they didn’t last—cheap silicone that faded after a few days. The metal parts on those also rusted quickly, whereas this one looks like titanium and feels much more premium. It fits perfectly with my Whoop device and stays secure during workouts. I highly recommend it!

I had issues with the Whoop clasp breaking, but this strap is soft, the buckle is strong, and it looks and feels premium.

does not fit a whoop 4.0, don't waste your time buying this

Nice looking band but caused contact dermatitis after wearing while exercising/sweating.

I ordered this to try out the style, having two of the knit-style band. It has a velvety texture that doesn’t seem to hold onto dirt. The band adjustment seems to hold fine and attaches seamlessly, just like my other two whoop branded bands. The one compromise is that it does get a bit sweaty if you’re working out, but wipes dry easily. I have worn it for the last two weeks and have no complaints. Will update if it wears prematurely.
