Knebel mit Atemloch

Wasn't sure about the perforated ball at first, but it makes a real difference when you're wearing it for a while. The airflow keeps things comfortable and the straps adjust easily for a snug fit.

The breath hole in the ball actually works — I could breathe through my nose easily and didn't feel panicky at all. Straps adjust fine and the black finish looks exactly like the photos.

The breathable holes in the ball make a huge difference for longer sessions, since I can actually breathe through my nose without feeling panicked. The straps adjust easily and stay put, and the ball itself feels solid without being uncomfortably heavy.
