Level 4 Body Armor: Weighing Protection Against Comfort

Level IV plates offer the highest level of protection against rifle threats. They can stop armor-piercing rounds like the dreaded .30-06 M2 AP "Black Tip". For those facing high-powered rifles, Level IV armor is a must-have. But that protection comes at a cost - Level IV plates tend to be heavier and thicker than lower-rated armor. This can impact comfort and mobility. It's important to weigh your need for protection against the realities of all-day wear.

What threats does Level 4 armor protect against?

By definition, Level IV plates are tested to stop .30 caliber steel core armor-piercing (AP) bullets (U.S. Military designation M2 AP). This includes other lesser threats. If it can stop M2 AP, it can handle the rest. In plain English, Level IV plates are made to defeat the most common rifle rounds seen in combat. This includes 5.56 NATO, 7.62x39, and even the big .30-06 Springfield. If it comes out of a rifle, chances are Level IV can stop it.

How heavy are Level IV plates?

The weight of Level IV plates varies by size and manufacturer. In general, you're looking at 7-8 lbs per plate for a 10x12 inch shooter cut single curve plate. The chart below shows some common options:

Brand	Plate Size	Plate Weight
Hoplite	10x12 Single Curve	7.4 lbs
Highcom	10x12 Single Curve	7.3 lbs
RMA Armament	10x12 Single Curve	7.5 lbs

Add a front and back plate, and you're looking at around 15-16 lbs of armor weight alone. Throw in a plate carrier, and your loadout can quickly approach 20 lbs. For reference, a gallon of water weighs about 8 lbs.

Thickness of Level 4 body armor plates

The thickness of Level IV plates also impacts comfort. Most Level IV plates measure around 1 inch thick. Compare that to 0.6 inches for Level III or 0.8-1.2 inches for Level III+. That extra thickness can make a difference in how the plate sits against your body. A thicker plate may be more noticeable and could push the carrier further off your torso. This can affect shoulder strap placement and overall fit.

How long can you comfortably wear Level IV body armor?

The length of time you can comfortably wear Level IV plates depends on several factors - your physical conditioning, the fit of your plate carrier, and environmental conditions. In general, most people start to feel the weight after a couple hours of continuous wear. If you're wearing Level IV plates all day, look for opportunities to take a load off. Sitting down, taking short breaks, or temporarily removing your plate carrier can provide much-needed relief. Stay hydrated and be mindful of fatigue.

Do Level 4 plates affect mobility?

The bulk and weight of Level IV plates can hinder mobility, especially in tight spaces or when getting in and out of vehicles. The added thickness may make it harder to shoulder a rifle or bend at the waist. Opting for a shooters or swimmers cut plate can improve range of motion. Multi-curve plates that match the body's contours tend to move better than flat plates. Proper fitment of the plate carrier is also key to maximizing mobility with Level IV armor.

Ceramic vs steel Level IV plates

When it comes to Level IV protection, you generally have two material choices: ceramic or steel. Ceramic is the most common type of Level IV plate. It tends to be lighter than steel but is more expensive and has a shorter lifespan. Steel Level IV plates offer a budget-friendly option, but the added weight and spalling (fragmentation) risk are significant drawbacks. For most users, ceramic is the way to go for Level IV.

Foam or padded plate backers for Level 4 plates

To improve comfort, some choose to add foam backers or padded plate backers to their Level IV plates. These sit between the plate and the body, providing a cushioning layer. Plate backers can make a difference in long-term comfort, especially if you're wearing a minimalist plate carrier. Just be sure to account for the added thickness when sizing your carrier. Shop our selection of foam and padded plate backers.

Tips for improving comfort with Level IV armor

Beyond plate material and backers, there are other ways to improve comfort in Level IV armor: 1. Ensure your plate carrier is properly adjusted. Shoulder straps should be tight but not digging in. The cummerbund should be snug around your torso. 2. Consider a padded plate carrier. Look for options with built-in shoulder pads, mesh lining, and breathable materials. 3. Train with your Level IV armor setup. Acclimating your body to the weight and bulk takes time and consistency. 4. Use the right clothing. Opt for a snug-fitting base layer to reduce chafing. Moisture-wicking materials can help manage sweat.

Best Level IV plates for comfort and weight

If comfort and weight are your top priorities, look for Level IV plates that prioritize these factors. Some top picks: - Hesco 4800 - A thin, lightweight multi-curve plate - Highcom Guardian 4S17M - A 7.2 lb multi-hit plate rated for special threats - Hoplite 26605 - A multi-curve swimmer cut plate for improved range of motion No matter what, remember that Level IV plates are the heaviest armor option. Go in with realistic expectations and be ready to train with your setup.

Multi-curve vs single-curve Level 4 plates

More and more, plate manufacturers are moving to multi-curve designs for Level IV plates. This means the plate is curved both vertically and horizontally to better match the shape of the human torso. Multi-curve plates tend to be more comfortable and provide better coverage than single-curve or flat plates. They sit closer to the body which aids in weight distribution. If given the choice, opt for a multi-curve plate.

Sizing Level 4 body armor plates to your body

Getting the right size plate is crucial for comfort and protection. A plate that's too small leaves gaps in coverage. A plate that's too big will be cumbersome and uncomfortable. To find your plate size, measure your chest width and length. Most manufacturers provide sizing charts to help you choose based on your measurements. When in doubt, size up for more coverage.

Mixing protection levels - Level IV plates with Level III+ or III sides

Some choose to mix-and-match protection levels, using Level IV plates in the front and back with Level III+ or III plates on the sides. This can shave some weight and bulk compared to an all Level IV setup. The tradeoff is less protection on the sides, where many vital organs reside. Ultimately, it's a personal choice based on your threat assessment and comfort needs. Shop our selection of Level III and Level III+ side plates.

Maintaining and replacing Level IV body armor plates

Level IV ceramic plates have a lifespan of around 5 years, after which they should be replaced. Steel plates can last much longer, but should be inspected regularly for damage or corrosion. To extend the life of your plates, store them in a cool, dry place out of direct sunlight. Avoid dropping or impacting the plates, as this can cause unseen damage that compromises ballistic performance.

Are Level IV plates worth the added weight?

Only you can decide if Level IV plates are worth the added weight and bulk. It's a highly personal choice based on your needs and risk assessment. If you're likely to face high-powered rifle threats, Level IV armor is the way to go. The tradeoff in comfort is worth the potentially life-saving protection. But if you're more concerned with handgun or general fragmentation threats, Level III or III+ plates may suffice.

Bottom line - Protection vs comfort

At the end of the day, choosing body armor is a balancing act between protection and comfort. Level IV plates offer the highest level of rifle protection currently available, but that protection comes with added weight and bulk. Assess your threats, choose quality plates that fit your body, and train with your setup. Remember, the best armor is the armor you actually wear. Opt for the level of protection that allows you to stay comfortable and alert throughout the day.
