Questions & Answers

Is this a genuine original part?

This is a genuine Seago product, supplied in original retail packaging with all safety manuals and the pre-installed CO2 cylinder.

How do I know if it is compatible?

This is a "one size fits all" adult lifejacket suitable for chest sizes up to 55 inches and users weighing over 40kg. If you require a tether attachment, please look for the Seaguard "With Harness" version.

What happens if it gets splashed by rain or waves?

The UML Mk5 automatic system requires total immersion to activate. Light rain or spray will not cause the lifejacket to inflate; it must be fully submerged in water to trigger the firing mechanism.

Note: Please verify your safety requirements before purchasing. This model does not include a safety harness D-ring.

For the products under £150 the shipping is £6.99.
