The BrightLine Bags B4 SWIFT Modular Gear Bag is one of the most popular flight bags in aviation, designed specifically for VFR pilots, flight instructors, aircraft owners, and business travelers who need exceptional organization without unnecessary bulk. Built around the innovative BrightLine FLEX System, the B4 SWIFT offers ample room for two aviation headsets, an iPad or Electronic Flight Bag (EFB), charts, handheld radios, charging accessories, and everyday cockpit essentials—all in a compact, modular design.
At the heart of the B4 SWIFT is a 4-inch Center Section (CS4) that provides generous storage while maintaining a streamlined profile. The modular FLEX System allows you to customize your bag as your needs evolve by adding or removing compatible center sections and accessories. Remove the center section and (with the optional Slim Handle Kit) convert the B4 into the ultra-slim B0 SLIM, giving you two highly functional bags in one.
The B4 SWIFT includes two versatile side pockets:
-
Side Pocket Echo – An insulated, adjustable pocket designed to securely hold a water bottle.
-
Side Pocket Foxtrot – A large zippered storage pocket perfect for handheld radios, batteries, cables, flashlights, or other flight essentials.
Whether you're flying cross-country, instructing students, commuting to the airport, or traveling for business, the B4 SWIFT keeps your gear organized, protected, and easily accessible.
