Mustang HIT Orange Automatic Inflatable Work Vest

The Mustang Survival HIT Inflatable Work Vest, model MD3188, is a low-profile automatic vest built for all-day wear in hot conditions.

A work vest is a specific classification, not a description: if it does not say work vest, it is not one. That distinction matters where a job requires one, since a recreational inflatable of similar appearance will not satisfy the requirement however comfortable it is.

HIT stands for hydrostatic inflation technology, which fires on water pressure rather than on contact with moisture. That is what stops a vest inflating in heavy spray, rain or a wet deck, which is the failure that makes crews stop wearing automatic vests altogether.

The low-profile fit adds mobility while cutting heat build-up, which is what makes all-day wear realistic. A vest that is uncomfortable in heat gets taken off, and a vest that is off does nothing at the moment it is needed. Explore more life jackets and PFDs.
