This Rebreather Bag connects to your gas mask hose and has a shut off valve at the other end.
 The wonderful rubber smell of this bag is a big plus for the rubber fetishist.
But the bag is mainly used to enhance breath control play.
If you exhale and re-inhale in the bag, the oxygen level drops.
The valve at the other end of the bag allows you to regulate the intake of fresh air.
 Breath control play is great fun, especially in combination with bondage.
But safety first: solo breath play is a known killer in the kink scene.
NEVER play alone.
NEVER leave your partner unattended, not even for a minute.
