Pilots flying high-performance fighter aircraft experience intense physical stress from rapid acceleration. Positive G-forces push blood away from the brain and toward the lower extremities. Without protection, this causes vision loss, blackouts, and eventually G-induced Loss of Consciousness — better known as G-LOC.

Anti-G suits are designed to counter this by applying pressure to the lower body during high-G maneuvers. This pressure helps maintain blood flow to the brain and prevents G-LOC during flight.

The anti-G suit isn’t a new concept. It has been used in military aviation since World War II, with early versions tested by both Allied and Axis powers. Modern versions like the CSU-13B/P and CSU-15A/P are used across multiple airframes including the F-15, F-16, A-10, and F-18.

Vinyl Technology’s G suits are critical for pilots in fast jets capable of pulling more than 6Gs during normal operations. Some suits, including those manufactured to MIL-DTL-83406D standards, support protection up to 9G+.

What Goes Into an Anti-G Suit

The CSU-13B/P and CSU-15A/P anti-G suits are engineered to reduce the risk of G-LOC by delivering pressurized support to the lower body during high-G flight. These suits are standard across many combat aircraft and are built for both performance and durability in demanding operational settings.

Each suit includes a fire-resistant aramid cloth outer shell. This material protects the wearer from heat and flame exposure while maintaining structural integrity under pressure. Inside the shell is a bladder system made from polyurethane-coated nylon. The bladder inflates in response to increased G-forces, exerting pressure on the body to keep blood flowing toward the brain.

The bladder system targets the abdomen, thighs, and calves. These are the primary regions where blood pools during acceleration. By compressing these areas, the suit counteracts the downward pull and helps the pilot stay conscious and responsive.

Functional components include a hose that connects to the aircraft’s anti-G system, waist and leg entrance slide fasteners for secure donning, and six lacing zones with covers that allow fine-tuned adjustment. The suit also features two leg pockets with slide fasteners to accommodate mission essentials.

Performance Expectations for Modern Anti-G Garments

Modern anti-G suits like the CSU-13B/P and CSU-15A/P are expected to perform under extreme flight conditions, providing protection up to and beyond 9G. This level of performance is vital for pilots flying aircraft like the F-16 or F-15, which regularly push the limits of acceleration. The suit’s bladder must respond instantly to pressure cues from the aircraft system, delivering reliable compression with every maneuver.

Comfort, fit, and size variety are central to performance. A poorly fitted suit can reduce effectiveness or even interfere with flight operations. These suits are available in seven sizes to accommodate different body types, and lacing areas allow for fine adjustments at the waist and legs. Comfort also affects pilot focus and endurance, especially during long missions or multiple sorties in a day.

Aircraft compatibility is non-negotiable. The suits must integrate with onboard life support and anti-G systems without failure or lag. The hose, connectors, and bladder response all need to meet exact specifications so pilots can count on the system to activate precisely when needed.

All of this ties back to MIL-DTL-83406D, the governing specification for CSU-13B/P and CSU-15A/P garments. This document defines materials, pressure response, hardware, and durability requirements. Manufacturers must meet every line item in that spec to produce garments that qualify for operational use.

Production Standards and Testing Requirements

Producing an anti-G suit to military specifications involves meeting strict requirements outlined in documents like MIL-DTL-83406D, which governs every aspect of the CSU-13B/P and CSU-15A/P suits — from material composition to hardware placement to pressure performance. These specs impact sourcing, assembly methods, and even the way each unit gets packed and labeled.

Aviation garments used in military applications follow a set of QC benchmarks that go beyond basic dimensional checks. Bladders must pass pressure decay tests. Stitching must meet thread count and seam strength standards.

Each component, from the hose connectors to the slide fasteners, gets checked for compliance with specific tolerances. Visual inspection alone is inadequate. Garments must be measured under load, tested in simulated use conditions, and sometimes reviewed by government inspectors before shipment.

For gear that sees operational use, a strong qualification and testing program is essential. Failures in the field can cause blackouts or worse during flight. Manufacturers that supply anti-G garments to defense contractors or government agencies need to demonstrate repeatable compliance. That includes batch testing, retention samples, detailed lot traceability, and complete documentation.

Why Outsourcing to a Qualified Anti-G Suit Manufacturer Matters

Manufacturing anti-G suits isn’t like stitching together basic workwear. The materials behave differently, the performance requirements are high, and the margin for error is about zero. A suit that fails under pressure puts lives at risk. That’s why reliability and deep technical experience are the minimum requirements.

Bladder construction is one of the harder parts to get right. Polyurethane-coated nylon isn’t difficult to source, but it takes skill to cut, weld, and seal it in a way that passes pressure decay testing. Add in aramid outer shells, complex lacing systems, and hose interface points — and now you’re in a production environment that needs tight process control, trained operators, and the right machinery.

Manufacturers and commercial sewing services providers must hold Qualified Producers List (QPL) status. Companies have to maintain production standards, pass periodic inspections, and comply with specs like MIL-DTL-83406D. Anyone off the list isn’t supposed to be supplying gear for military or aerospace use.

Procurement teams in defense and aerospace need partners who know how to work inside those boundaries. That means understanding contract language, meeting packaging requirements, and being ready for audits. Vinyl Technology has handled those expectations for over 40 years. We’ve produced thousands of anti-G garments that are currently in use across multiple airframes and branches. We know the specs, we follow the rules, and we deliver on schedule.

We manufacture anti-G suits and related textile gear for government and aerospace contractors. If you need a qualified anti-G suit manufacturer with the experience and certifications to meet defense standards, reach out. We can help you meet your project needs without guesswork.

How We Support Defense and Aerospace Programs

Vinyl Technology brings over 40 years of manufacturing experience to military and aerospace projects. Our anti-G suits are in service with air forces around the world and are built for use in high-performance aircraft like the F-16, F-15, A-10 & F-18.

We produce every garment with a focus on precision, durability, and consistency. Our process supports fast turnaround and repeatable quality. Most production setups require little or no tooling, which helps shorten lead times and reduce cost without compromising accuracy.

Each project benefits from experienced staff, controlled environments, and a production system built for complex textile and polymer film assemblies. We meet contract requirements, maintain documentation, and stay focused on supporting mission-ready equipment with dependable results.

Let’s Talk About Your Program Needs

Aerospace contractors, defense buyers, and procurement teams — if you’re sourcing anti-G suits or related textile gear, we’re ready to support your build. Vinyl Technology manufactures for other companies and government agencies. We don’t sell retail products, we’re a custom sewing contractor. Everything we produce is custom-made for clients with technical requirements and real-world performance demands.

We bring decades of experience, industry approvals, and the kind of production capability that’s been proven in the field. Our team understands the materials, the specs, and the systems these suits need to connect to.
