HydroKnit Nylon Sport Band Compatible with Whoop 4.0 | Soft, Elastic, Fast-Drying, Water-Resistant, and Comfortable Replacement Strap for Active Lifestyles

It’s really the hydroknit band, good replacement for WHOOP users. Band is stretchy and dries really fast after washing hands or shower. Gave 4 stars because the loop that locks it in place is loose and doesn’t stay place, snaps off easily once you remove the band. Also where the logo is supposed to be isn’t aligned properly and is very visible.
