It’s ok
Good for a few weeks but loses elasticity. Maybe if I had a few and would rotate them out it would be better

BEST EVER!!!! Great for lots of swimming and beach
BEST WHOOP BAND EVER. super lightweight, not bulky and doesn’t smell. Dries super quick and the color is stunning. Works with the charger. I’ll be buying a lot more of these. I love it so much. Very smooth and thin band; unlike the knit ones that collect water and irritate my wrist. This one is perfect and super comfortable. Could not recommend it more
