The UARM EVV™ (Exchangeable Vest Ventilation) is a modular comfort and thermal-management insert designed to sit between your body and your plate carrier. Sold as a set of two — one for the front plate pocket zone and one for the back — the EVV uses a large-cell 3D-grid channel construction to draw heat and moisture away from your torso continuously. Beyond comfort, the system reduces the backface deformation impact on the body to virtually zero when worn behind armor. Available in standard sizes S, M, L, and XL, each sized to cover the same zone as the corresponding UARM hard plate.

Who this is for

• Tactical operators and military personnel: who wear plate carriers for extended missions in hot or humid environments and need to manage heat and moisture without removing their kit.
• Law enforcement and security professionals: who wear body armor daily and want a washable, replaceable comfort layer that keeps odor and chafing under control shift after shift.
• Trainers and serious shooters: who spend long hours at the range or in force-on-force exercises and want reduced fatigue from heat buildup inside their carrier.

Compatibility with plate carriers

The EVV attaches to any plate carrier via a large adhesive Velcro® panel. Installation and removal take approximately one second. While the system is sized to match all UARM plate carriers and hard plates directly, it can physically attach to third-party carriers that present a compatible Velcro field. Using an EVV that is larger than your carrier's plate zone may limit shoulder mobility; using one that is smaller reduces ventilation coverage. Contact us if you want to confirm fit before ordering.

Ventilation and thermal management

Ventilated panels, padded load-bearing points, and a multilayered liner work together to deliver continuous airflow across the torso. The large-cell design creates open air channels that push warm, moist air out rather than trapping it against the skin. This reduces the fatigue associated with heat accumulation during prolonged wear and lowers the risk of skin irritation, chafing, and infection in high-humidity conditions.

NIR (near-infrared) materials across the EVV reduce your detectable heat signature, limiting visibility to enemy night-vision and thermal imaging systems. This makes the EVV relevant not only as a comfort layer but as a signature-management tool during low-light or night operations.

Backface deformation reduction

When worn behind a hard armor plate, the EVV's internal structure acts as a damper, absorbing and distributing the residual energy of a backface deformation event. The system reduces the BFD impact transferred to the body to virtually zero. This is a secondary protective benefit on top of the plate's own ballistic performance — the EVV itself carries no ballistic rating.

Maintenance and serviceability

Because the EVV detaches in seconds, you can pull it before a mission, wash it with your regular laundry, and reinstall a clean unit without touching the carrier itself. This keeps the vest serviceable and odor-free far longer than systems with integrated padding. UARM recommends having a spare set so one is always clean and ready.

All materials meet MIL-SPEC standards for functionality, durability, and longevity under field conditions.

Specifications

Frequently asked questions

What plate carriers does the EVV work with?

It is sized and designed to fit all UARM plate carriers directly. It can attach to third-party carriers that have a compatible Velcro field, though fit and coverage efficiency will vary by carrier model. Contact us with photos of your carrier and we can help assess compatibility before you order.

Does the EVV have a ballistic rating?

No. The EVV is a comfort and thermal-management accessory with no ballistic protection rating. Its BFD-damping benefit applies only in combination with a ballistic hard plate — it does not stop or slow projectiles on its own.

How do I choose the right size?

Size matches the hard plate you are using. If you run a size M plate in your carrier, order a size M EVV. Using an oversized EVV can push on your shoulders and restrict movement; an undersized EVV reduces the ventilated coverage area. Refer to the Size Chart in the product's Tech Specs tab or contact us for guidance.

Can I use the same EVV on both the front and the back?

Yes. The EVV is ergonomically designed to fit equally well on the front and the back. Each set ships with two identical pieces so you can run one in each position simultaneously.

How do I clean the EVV?

Yes, it is machine washable. Detach it from the carrier — which takes about one second — and wash it with your regular laundry. Having a spare set on hand means you can swap in a clean unit immediately and never wear a dirty EVV.

Does the EVV work with soft armor panels or only hard plates?

It depends on the carrier configuration. The EVV is designed around the hard plate zone. It can be used in carriers that also accept soft armor, but the BFD-damping benefit is specifically relevant to hard plate impacts. For soft-armor-only setups, the primary benefit is thermal management and moisture wicking.
