Mustang Survival MIT 100 Convertible A/M Inflatable PFD, Red

The Mustang Survival MIT 100 Convertible is an automatic and manual inflatable life vest built for boaters who want real protection without the bulk of a foam PFD. It stays flat and low-profile until you need it, then fires automatically the moment it hits the water. Prefer to trigger it yourself? Pull the manual handle. And if you want to shut off the automatic side entirely, the included inflator cap lets you convert it to manual-only in about a minute.

MIT stands for Membrane Inflatable Technology, Mustang's way of keeping the inflation cell folded flat inside a slim nylon shell. What that means on the water is a vest you'll actually wear. It sits close to the body, doesn't ride up on your neck, and won't cook you on a hot afternoon the way a thick foam vest does. For anglers working a deck all day, or cruisers standing a long watch, comfort is the difference between wearing your PFD and leaving it in the locker.

The automatic side uses a water-sensitive trigger that fires the CO2 cylinder as soon as it's submerged. That's the setup most boaters want, because in a real overboard situation, especially if you're knocked out or disoriented, you don't have to do a thing for the vest to do its job. But there are times manual-only makes sense. Kayak anglers who take intentional dunks, or anyone working around heavy spray who's had nuisance inflations, can pop in the inflator cap and switch off the auto function. You still get instant inflation from the pull handle and a backup oral tube. It's your call, and this vest gives you both.

Once inflated, it delivers 38 pounds of buoyancy. That's plenty to keep an adult face-up and floating in calm to moderate water. Worth being honest here. If you're heading well offshore in heavy weather with boots and layers of foul-weather gear, 38 pounds sits on the lighter end of what you'd want, and adding a crotch strap makes good sense. For inshore fishing, day sailing, and general powerboating, it's right in the sweet spot, and most boaters spend their whole season in exactly that kind of water.

The universal adult fit adjusts across a wide range of chest sizes, so one vest covers most of the crew and swaps easily from one person to the next between trips. The high-visibility red shell helps a spotter find you fast if you go over, which matters more than people think once the sun drops and the water gets choppy. Keep in mind this is a Type V device, which means it only counts toward your Coast Guard carriage requirement when it's actually worn, not when it's stuffed in a locker. So wear it. That's the whole point of a vest this comfortable.

Inflatable vests need a little more attention than foam. Store it dry. Salt and humidity are hard on the automatic bobbin, and a damp locker can trigger a false inflation or corrode the sensor over a season. Check the status indicator before every trip, rinse and dry the vest after a wet day, and give it a full look-over at the start of each season. If it ever deploys, rearm it with the Mustang re-arm kit that matches this exact model. Don't mix cartridge sizes or caps from another vest, because a mismatched cylinder is the most common cause of a first-use leak.

This listing is for a single vest in red with the inflator cap included. It's a smart pick for boaters who've been meaning to upgrade from a foam vest they never actually wear, and it's comfortable enough that you might forget you've got it on until the day you're glad you did.
