Great Band!

I ordered this band about a month ago, before this I had been using the silicone/rubber fitness band and it didn't agree with my skin. This one has been perfect and feels amazing! Highly recommend.. The color is very true to the image.

Great color, superknit bands are nice

The Whoop super knit bands come in a wide range of colors/designs and wear well. One thing I like is that they dry quickly (relatively), so you can wear them when working out and still have them look good when at dinner. Having options to coordinate the band color with your wardrobe is nice and can add a bit of color to your fashion.

Love my whoop

I had the 4.0 which I loved, and the transition to the 5.0 was easy. Gifted my old Whoop to my partner to test, and back to work with my new toy. My journey with Whoop has been life changing. I'm a cross-fitter/functional endurance athlete, so knowing my recover is key. But the sleep element has been so powerful. Gotta love data!
