The Evolution of Paddleboarding Safety Gear

Before we dive deep into the Onyx M16 Inflatable Belt Pack, let’s take a moment to understand the journey of water safety equipment. Personal flotation devices have come a long way from the bulky, uncomfortable life jackets of the past.

In the early days of stand-up paddleboarding (SUP), water enthusiasts were limited to rigid, restrictive safety gear that often felt more like a burden than a lifeline.

The water sports industry has witnessed a remarkable transformation over the past decade. Manufacturers like Absolute Outdoor recognized the growing need for safety equipment that doesn’t compromise comfort or performance. 

This understanding gave birth to innovative solutions like the Onyx M16, which represents a paradigm shift in how we approach water safety.

The Science Behind Inflatable PFDs

Modern personal flotation devices are a marvel of engineering and design. The Onyx M16 isn’t just a piece of safety equipment; it’s a carefully crafted solution that combines advanced materials, intelligent design, and a deep understanding of water safety principles. 

The manual inflation mechanism is a testament to human-centered design, putting the user in complete control of their safety.
