wellenshop Lalizas Sigma 170N, 2355 review

The highest newton figure on the shelf, and the trigger mechanism named by model.

The bottom line The highest published buoyancy here, with the trigger named by model and a rescue loop — the only one on this shelf that thinks about getting you out.

What the maker puts in writing

  • 170 N instead of 150 N
  • Declared to ISO 12402-3 · stated to turn the wearer onto their back
  • Lalizas JS1 water-activated trigger · CO₂ cartridge · manual handle
  • Integrated rescue loop
  • Reflective strips · signal whistle
  • Wide adjustable waist belt · hook-and-loop bladder cover · transparent carry bag · from 40 kg

The mechanism, named

Mittels eines wasseraktivierten Auslösers (Lalizas JS1-Mechanismus).

A named trigger is not marketing. It is how you buy the right rearming kit two years from now, and how you know what the yellow part in the jacket actually is. Two other jackets on this shelf name UML; this one names JS1.

The loop

An integrated rescue loop, for securing on deck or lifting someone back aboard.

Every other item on this shelf is concerned with keeping a person afloat. This is the only one that also considers getting them out.

What goes unpublished

No service interval. No upper weight limit. No chest range. Two inflatable jackets on this shelf publish a 24-month first service and a full fit table.

Questions that come in about this one

What does 170 N buy over 165 N?

Five newtons of published buoyancy, on a shelf where two other jackets state 165 N in the same class. The seller frames it as margin for heavy clothing. All three figures are their makers’ declarations.

What is the rescue loop for?

Clipping the wearer to the deck, or lifting them back aboard. Getting an unconscious person out of the water is the part nobody plans for, and this is the only jacket on this shelf with a loop built in for it.

When does it need servicing?

Not published here. Two other inflatable jackets on this shelf state a first service no earlier than 24 months after the production date, read from the vest label. Every inflatable jacket has a service requirement; this listing does not give its interval.

Who this one is for

Boat work where the highest published buoyancy and a recovery loop both matter
