Together, these features provide practical flotation and additional security during onboard activities.

Automatic Inflation with LALIZAS JS1

The Sigma 170N features the LALIZAS JS1 automatic inflation mechanism.

Upon immersion in water, the system activates and releases CO₂ into the inflatable chamber. Consequently, the lifejacket provides emergency buoyancy without requiring manual activation.

A manual pull handle offers an alternative activation method when necessary.

Furthermore, the oral inflation tube allows additional inflation according to the manufacturer’s instructions.

The JS1 mechanism is designed for reliable marine operation. However, correct arming and regular inspection remain essential.

Integrated Safety Harness and Crotch Strap

The Sigma 170N Black Harness Lifejacket includes an integrated harness for additional onboard safety.

Its D-ring provides an attachment point for a compatible marine safety line.

As a result, the wearer can use the lifejacket as part of an appropriate deck safety arrangement.

The adjustable crotch strap helps prevent the inflated lifejacket from riding upward.

Moreover, its clip fastening allows convenient adjustment and removal.

The harness and crotch strap perform separate functions. The harness supports safety-line attachment, while the crotch strap improves lifejacket retention.

Only compatible safety lines should be used. Always follow the manufacturer’s fitting and operating instructions.

Protective Zipper and Plastic Buckle

This Sigma configuration combines a protective zipper with a plastic fastening buckle.

The zipper keeps the folded inflatable chamber enclosed during normal wear.

Meanwhile, the plastic buckle provides convenient fastening and removal.

Adjustable webbing helps maintain a secure fit during onboard activities.

Additionally, the compact outer cover reduces unnecessary bulk.

These features make the lifejacket practical for regular use during sailing and marine operations.

ISO 12402-3 Certification and Marine Safety

The Sigma 170N is certified according to ISO 12402-3.

This standard covers Level 150 lifejackets designed to provide appropriate emergency flotation.

The inflatable chamber offers 170N buoyancy when fully inflated.

In addition, the integrated harness provides an attachment point for a compatible safety line.

LALIZAS lists ISO 12401 approval for its integral black harnesses. Therefore, users should follow the specific harness documentation and approved operating limits.

Correct adjustment remains essential for both flotation and harness performance.
