Let’s talk about these nylon bands for the Whoop 4.0. First off, the breathability is a game-changer—especially if you’re like me and hate that clammy feeling after a workout. The double-layer nylon weave keeps things light, and the hook-and-loop closure stays put even during intense sessions.

But here’s the catch: that scratchy texture out of the box? Real. It’s like wearing a tiny burlap bracelet until you wash it a few times. And while the plastic clamshell design locks the tracker in securely (no accidental launches mid-burpee), it blocks the charging port. Major oversight if you ask me—nobody wants to swap bands just to power up.

Compared to OEM bands, these dry faster post-sweat or swim (huge win), but they lack that seamless ‘click’ when attaching. For $13 though? Solid backup straps with fun color options—just don’t gift them to someone who hates charging hassles.
