The Knockout is composed of 5 pieces: the mouthpiece, the stainless steel curved tube, the stainless steel straight tube, the connector and one way valve. You can disassemble the Knockout so it fits in the small cloth carrying case. Once disassembled you can take The Knockout just about anywhere: the park, a festival, the beach, your grandma’s house etc.
The Knockout is made of 100% stainless steel and food-grade silicone so it can take some wear n’ tear. Each piece was professionally designed to be party perfect. The mouthpiece allows for smooth chugging, while the stainless steel pieces allow for easy air flow into the bottle. The connector piece acts as a joint so the Knockout can be easily assembled/disassembled. Last but not least there is the one-way valve. Depending on the Knockout you have you may either have a cross slit valve or a duckbill valve. Both work to allow air to flow into the bottle but it does not allow beer to flow out of the bottle through the stainless steel tube.
