The invention provides a generally X-shaped utility garment comprising two main straps that form an ‘X-shape’ on a wearer's back and a cross-strap above the X shape to stabilize the garment on the wearer's body. The garment, referred to herein as a strapvest, provides a plurality of pockets and/or receptacles for carrying items the wearer needs to access easily. Its receptacles can be detachable, and a user can select which receptacles to have on the strapvest according to the wearer's immediate needs. It can be adjustable in size to fit a wide range of wearers, and can be adapted to carry many different types of items that are needed for work or recreation, by a combination of built-in pockets and other built-in carriers and optional modular receptacles that can be detachably mounted on the straps of the strapvest. It is more convenient for accessing the stored items than a backpack, which needs to be removed to access its contents; it carriers more and potentially heavier items than a utility belt without a tendency to pull the wearer's pants down; and it can be worn with a variety of different types of weather-related or protective outerwear because of its open design and potentially adjustable size.
