Questions & Answers
Is this a genuine original part?
This is a genuine Lalizas Sigma series lifejacket, a world-renowned brand for marine safety equipment, fully certified to international ISO standards.
How do I check the firing mechanism status?
The Sigma 170N features a built-in clear viewing window. If the indicator on the JS1 firing head is green, the unit is armed and ready for use. If it is red, it requires re-arming.
Does it come with a crotch strap?
Standard Lalizas Sigma lifejackets are designed for use with or without crotch straps; while many versions include them as standard, please check your specific package or purchase the Lalizas crotch strap (part 72081) separately for enhanced security.
Note: Always inspect your lifejacket before use. For replacement gas cylinders, use only Lalizas 33g CO2 re-arming kits to ensure total compatibility. Available at 4boats.co.uk.
