Product Care

During the COVID 19 pandemic, we have updated our product care recommendations to align with guidance from the CDC and Life Jacket Association. Please visit our COVID 19 page for detailed instructions on how to minimize risk.

EVERY USE Rinse after use, especially after use in salt water. Hang to dry away from sunlight.
OCCASIONALLY Hand wash in mild detergent to help prevent mildew, rinse and hang to dry. We like McNett’s Wetsuit and Drysuit Shampoo. McNett’s MiraZyme or Sink the Stink is good if your PFD has developed a funk, or you can use all natural Surf Remedy to shed the stink!
SEASONALLY Inspect PFD for tears and holes, be sure zippers and buckles are working properly. If material is faded the fabric has probably lost strength. Foam deteriorates over time, so test your PFD and be sure it keeps your mouth out of the water. If you notice fraying of fabric or straps, serious UV damage, or crushed foam, please discard and replace with a shiny new MTI PFD.


Manual Inflatable PFD Care

Sure, you haven't needed it yet, but is your inflatable PFD ready to be deployed in an emergency? Follow these tips to keep your MTI inflatable in ship-shape and ready to perform.

EVERY USE If the PFD has been submerged, open the shell, unfold the bladder and hang to dry.
SEASONALLY If you aren’t going to be using it for an extended period of time, back the cylinder out, making sure you don’t break the black plastic bayonet on the cylinder. Tuck the JERK tag inside so it can’t accidentally inflate if caught on something, but make sure you untuck it before use.
YEARLY Inspect for tears and fraying on the shell and straps. Open up the air bladder and visually inspect it. Check the CO2 cylinder for corrosion and make sure the black plastic bayonet is not broken. Ensure the inflation mechanism is working and the Jerk tab string is not frayed. Orally inflate the bladder using the red tube and make sure it will hold air for an hour.


Automatic Inflatable PFD Care

Arming Your Inflatable PFD

CO2 Cylinder Care

MTI inflatable PFDs use CO2 cylinders that have a black “bayonet” installed on the threads. This plastic piece makes installation quick, easy and secure. Once the CO2 cylinder has been properly installed, the small window on the inflator mechanism will be GREEN instead of RED. If you inflate the vest by pulling the JERK tab and puncturing the CO2 cylinder, the black ring is designed to snap off and trip the inflator, showing RED to alert you that your PFD needs rearming.

The left CO2 cylinder is unused and ready to be installed. Broken Bayonet The right CO2 cylinder has most likely been used and needs to be replaced.


If you are not careful when installing the cylinder, you can break the bayonet without puncturing it. It is possible to install an unused cylinder with a broken bayonet by pressing down the white prongs and inserting the cylinder normally.

CAUTION: The inflator will always show RED when a cylinder with a broken bayonet is installed. You should check before EVERY use to make sure the cylinder has not been punctured.


Corroded and rusted metal is weaker, and letting your CO2 cylinder get to this point can be dangerous, as it could accidentally puncture. Water is a corrosive environment, especially salt water, which is why we recommend checking your equipment every season and replacing before they get this far. Yikes!
