CQYD/I-100N Waist Life Jacket
Compact 100N Buoyancy with a Self-Positioning Inflatable Chamber
The CQYD/I-100N Waist Life Jacket is a compact personal flotation device designed for adult users who require reliable buoyancy support without the bulk of a conventional life jacket.
Worn around the waist, it uses a single independent air chamber and a 24g CO₂ cylinder to provide at least 100N of buoyancy. Its lightweight design allows greater freedom of movement, making it suitable for experienced swimmers participating in appropriate boating, swimming, fishing and recreational water activities.

Self-Positioning Inflatable Chamber
A distinguishing feature of the CQYD/I-100N is its patented chamber configuration.
After the air chamber is fully inflated, it automatically surrounds the wearer’s waist. The user does not need to continue holding the inflated chamber in position, helping the flotation device remain properly arranged around the body.
Rapid Automatic or Manual Inflation
The CQYD/I-100N can be activated by pulling the inflation cord or through contact with water. The product page states that the independent air chamber inflates in less than five seconds.
Once fully inflated, the chamber provides buoyancy intended to help keep the wearer’s head, neck and shoulders above the surface of the water.
The oral inflation tube provides an additional method for manually adding air to the chamber when required.
Visibility and Emergency Assistance
Reflective tape is fitted to the product to improve the wearer’s visibility in low-light conditions.
An integrated safety whistle provides an additional means of attracting attention and requesting assistance during an emergency.
Recommended Applications
According to the product information, the CQYD/I-100N can be used for suitable activities in:
- Ocean environments

Inflatable waist flotation devices are particularly suited to experienced swimmers seeking a compact alternative to a conventional flotation vest. They are best used in appropriate water conditions, including calm waters and situations where the user remains relatively close to shore.

Important Safety Information
The CQYD/I-100N is intended to provide protection against drowning, but it does not guarantee rescue or survival.
The product provides its intended buoyancy only after the air chamber has been completely inflated. Users must carefully read the operating instructions and product information before use and follow all information marked on the life belt.
CO₂ cylinders are stored under high pressure and must be handled carefully. Keep the cylinders away from children and use only cylinders that meet the product’s specified requirements.
Inflatable life belts are intended primarily for experienced swimmers. They are not designed for high-impact or high-speed activities such as water skiing or tubing. They are also not ideal for cold-water conditions or for boating alone without other people nearby.
Compact Flotation Support for Suitable Water Activities
Combining a waist-worn design, 100N minimum buoyancy, rapid inflation and a self-positioning air chamber, the CQYD/I-100N provides a compact flotation solution for suitable boating, fishing, swimming and recreational water applications.
