Interspiro BA systems are recognized worldwide as the pinnacle of breathing protection for professional firefighters. The latest models have been designed in cooperation with firefighting personnel, and feature a host of desired characteristics, both mechanical and electronic, with fire professionals in mind. For instance, the new Incurve system has a minimum of textile parts.
The Incurve is a new SCBA harness from Interspiro with a unique design developed together with firefighters – with every little detail in mind. With a minimum of textile parts, the Incurve harness is easy to clean, robust and lightweight, without compromising comfort. The shoulder straps and hip belt are non-textile to prevent contamination and designed to be body shaped for excellent ergonomics.
The back plate is made of heat-resistant polymer and Kevlar webbing for minimum weight (the standard Incurve weighs only 3.6kg) and the harness is ready for machine washing and decontamination.
The harness can be adjusted easily for different body sizes in four different size settings. The selected size is clearly visible from both the front and the back. Thanks to the practical design, the size adjustment can be made with the cylinder mounted on the back and without removing the apparatus from the fire truck.

The Incurve harness offers numerous features that have been reached through a ‘wish-list’ in consultation with many professional firefighters and fire managers from various fire brigades. These features include:
- Hip belt and shoulder straps move independently for maximum mobility.
- Large rescue handle – easy to grab to drag out firefighter in an emergency.
- Open back plate for good ventilation and low weight.
- Easy-to-handle and adjustable cylinder strap.
- Multiple attachment points for accessories.
- Small and light warning whistle.
