The A-4 is one of Entire Studios' numerous bomber styles, crafted from 16oz cotton canvas. It then features an enzyme wash that may cause slight variances in appearance. Two-way front zip fastening allows for various styling options, as the garment is outfitted with four compartments including waist pockets, a chest pocket, and an internal pocket. Rib knit trims are implemented at the collar, cuffs, and hem to complete the look.
