Blackout Sleep Mask with Built-In Stereo — Optimize Your Recovery Every Night
The Night Is When Your Body Rebuilds. Make It Count.
Sleep is the most underrated performance tool in your stack. Poor sleep destroys testosterone, spikes cortisol, tanks recovery, and kills focus. The Bento316 Sleep Mask blocks out 100% of light while delivering your favorite audio — so you can optimize every hour of sleep you get.
The Two-in-One Sleep Stack
Total blackout + stereo audio in one slim, weightless design. Unlike earbuds that fall out or headphones that press into your skull, the built-in flat speakers sit perfectly over your ears — no pressure, no discomfort, no wires pulling you awake.
