Sigma 170N Harness Lifejacket – Key Features
This automatic inflatable lifejacket combines reliable emergency flotation with practical safety equipment.
Its single inflatable chamber provides 170N buoyancy when fully inflated. In addition, the automatic inflation system helps provide flotation following immersion.
The integrated harness and crotch strap improve security during onboard activities.
Key features include:
- 170N rated buoyancy.
- Automatic inflation upon immersion in water.
- Manual inflation activation option.
- Oral inflation tube with non-return valve.
- Integrated safety harness with attachment point.
- Crotch strap for improved lifejacket retention.

Automatic Inflation and Emergency Flotation
The Sigma 170N features an automatic inflation system designed for marine emergencies.
Upon immersion, the inflation mechanism activates and releases CO₂ into the inflatable chamber. Consequently, the lifejacket provides buoyancy without requiring manual activation.
A manual pull handle provides another activation method when needed.
Furthermore, the oral inflation tube allows inflation according to the manufacturer’s instructions.
The inflatable chamber is designed to support the wearer in the water. However, correct fitting and regular maintenance remain essential.

Integrated Safety Harness and Crotch Strap
The Sigma 170N Harness Lifejacket features an integrated harness for additional onboard safety.
Its attachment point allows connection to a suitable marine safety line. As a result, the wearer can use the lifejacket within an appropriate deck safety system.
The crotch strap helps prevent the inflated lifejacket from riding upward.
Moreover, the adjustable webbing helps achieve a secure fit without restricting normal movement.
The harness and crotch strap serve different purposes. While the harness provides a safety-line attachment, the crotch strap improves lifejacket retention.
Always use a compatible safety line and follow the manufacturer’s instructions.
Navy Blue Design and Wearing Comfort
This version features a navy blue protective outer cover.
The compact construction reduces bulk during normal onboard activities. Meanwhile, adjustable straps help maintain a comfortable fit.
Its lightweight design makes the lifejacket practical for regular use during sailing and marine operations.
In addition, the outer cover protects the folded inflatable chamber during storage and everyday wear.
The combination of comfort and safety makes this configuration suitable for adult boat users.
Visibility and Emergency Safety Equipment
The LALIZAS Sigma inflatable lifejacket incorporates important emergency safety features.
Its high-visibility inflatable chamber helps rescuers identify the wearer in the water.
Retroreflective material improves visibility in poor lighting conditions. Furthermore, the integrated whistle provides an audible signalling method.
Safety features include:
- High-visibility inflatable chamber.
- Retroreflective material.
- Integrated emergency whistle.
- Automatic CO₂ inflation system.
- Manual inflation activation.
- Oral inflation provision.
- Integrated safety harness.
- Crotch strap for improved retention.
Together, these features support flotation, visibility, and practical onboard safety.
