Abyssal zone. Layers of the pelagic zone The abyssal zone is the abyssopelagic layer or pelagic zone that contains the very deep benthic communities near the bottom of oceans. "Abyss" derives from the Greek word ἄβυσσος, meaning bottomless. At depths of 4,000 to 6,000 metres (13,123 to 19,685 feet), this zone remains in perpetual darkness and never receives daylight. It is the deeper part of the midnight zone which starts in the bathypelagic waters above.[1][2] The area below the abyssal zone is the sparsely inhabited Hadal zone.[3] The zone above is the bathyal zone.[3] These three zones belong to the deep-sea realm.

A flight suit is a full body garment, worn while flying aircraft such as military airplanes, gliders and helicopters. These suits are generally made to keep the wearer warm, as well as being practical (plenty of pockets), and durable (including fire retardant). Its appearance is usually similar to a jumpsuit. A military flight suit may also show rank insignia. It is sometimes used as a combat uniform in Close Quarters Battle or Visit, Board, Search, and Seizure situations, for its practicality. History[edit] A flight suit worn in 1925 As aviation developed in unheated open cockpits, the need for warm clothing quickly became apparent, as did the need for multiple pockets with closures of buttons, snaps, or zippers to prevent loss of articles during maneuvers. Where bomber pilots could wear their dress uniforms as flight gear, fighter pilots needed a uniform that functioned in the tight confines of the typical fighter plane cockpit.

Protective equipment may be worn for job-related occupational safety and health purposes, as well as for sports and other recreational activities. "Protective clothing" is applied to traditional categories of clothing, and "protective gear" applies to items such as pads, guards, shields, or masks, and others.
