Mustang MIT 150 Convertible Inflatable PFD - Red

When you're heading offshore or working a shoreline all day, a life vest you forget you're wearing is the one you'll actually keep on. The Mustang MIT 150 Convertible Inflatable PFD in red is built around that idea. Its exclusive Membrane Inflatable Technology (MIT) and high-tenacity nylon face fabric keep the profile low and the fit flexible, so it sits close without the bulk of a foam vest. At 1.75 lbs, it stays out of your way whether you're trimming a sail, running a center console, or casting from a kayak.

The headline feature is right in the name. This PFD converts between fully automatic and manual-only inflation by swapping the inflator cap, and both caps are included in the box. In automatic mode, a water-soluble bobbin dissolves on immersion and fires the CO2 cylinder for hands-free deployment, which is what you want if you're knocked overboard unconscious. Switch to the manual cap and the vest only inflates when you pull the handle, the setup a lot of river runners and anglers prefer so a wet deck or a rain squall doesn't set it off. Making the change takes a minute at the dock, not a trip to a dealer.

Buoyancy is a genuine 38 lb, enough to turn most wearers face-up and keep an airway clear well offshore. The vest carries a USCG Type V approval, so it counts as your required wearable PFD as long as it's worn. Front entry with a single buckle makes it quick to don and doff with gloves on, and the one-fold design means repacking after a test inflation or a re-arm isn't a wrestling match.

Mustang built in the small touches that matter on the water. A zippered hip pocket stows the spare converter cap where you can find it. An inflator inspection window and access flap let you confirm the cylinder is sealed and the bobbin is in date without tearing the cover open, so your pre-season safety check takes seconds. There's a D-ring positioned for an engine cut-off switch lanyard, handy on a tiller skiff or a PWC where a kill-switch tether is the difference between a swim and a runaway boat.

The shell is 500D Cordura nylon, the same abrasion-resistant fabric that holds up to a season of rubbing against rod holders, hiking straps, and console corners. Fit is universal, sized for chest measurements of roughly 76 to 132 cm and recommended for wearers over 80 lbs, so one vest covers most adults on the boat. It's a strong pick for boating, sailing, fishing, and paddling where you want protection without giving up mobility.

A few honest notes from people who use these hard. The waist and chest straps run generously, so slimmer wearers will want to snug everything down before a day of tacking. Anyone caught in brackish or salt spray should rinse the vest in fresh water regularly and check the oral inflation tube each season, since salt is tough on any inflatable over time. And if you inflate it, whether by accident or on purpose, you'll need the correct re-arm kit before it's ready again. For this model that's Re-arm Kit F (Model #MA7113), and keeping a spare aboard means a single accidental firing doesn't end your day.

Set-up out of the box is straightforward. Decide how you'll mostly use the vest, thread the matching cap, and store the spare in the hip pocket. Log the cylinder and bobbin dates so you know when the automatic bobbin is due for replacement, since a dissolved or expired bobbin won't fire when you need it. A few minutes at the start of the season keeps the vest honest for the rest of it.

This is a wearable inflatable, not a foam vest, so it isn't rated for non-swimmers or for kids, and it needs to be worn to count toward your requirement. For the boater who hates bulky vests and ends up leaving them in the locker, though, the MIT 150 Convertible is the kind of PFD that actually stays on. That's what makes it safe.
