Gray Man | How To Blend In By Hiding In Plain Sight

By Just In Case Jack | Last Updated: May 21, 2019

Gray Man - How To Blend In

Today, we’re going to discuss the gray man theory, otherwise known as “hiding in plain sight.” But not about hiding “things” using diversion safes, but hiding YOU.

We’re going to dissect the psychology behind the Gray Man theory.

The gray man concept is not new. Others have written about it, and we’ve even touched on it in previous articles as well:

“Sometimes the best hiding place is the one that’s in plain sight.” – Stephanie Meyer

But today, we’ll dive even deeper into this intriguing psychological phenomenon, such as:

The “Gray Man” concept is a collection of techniques to operate in a way that won’t draw attention to yourself.

It’s the science behind blending into your environment. It’s a way to hide in plain sight. It allows you to move through a group or crowd unnoticed.

At its core, the concept relies on our brain’s Reticular Activating System (RAS).

You can think of a RAS as your brain’s information filter.

What do filters do? They remove unwanted or unnecessary items. In the case of your brain, it filters out the “unnecessary” sensory data streaming in.

And you should take a moment to THANK your RAS system. Because without it, you’d become immediately incapacitated. You’d become overwhelmed by the vast amount of data entering your brain.

Our brains are not able to process most of the sensory data coming in every millisecond. So without it, you’d be in constant sensory overload!

Several Examples Of Your RAS In Action

A Stroll Around The Block

Here’s an example to explain what’s going on…

When you take a leisurely stroll around the block, your RAS is working hard in the background. You may think you’re seeing lots of “stuff” but you’re only aware of a fraction of the visual data coming in. You’re missing way more than your “seeing”.

Let’s say you notice a few minute details on your walk. Maybe you saw a bunch of flowers, all the cars passing by, you met a friendly dog and a few smiling neighbors.

But if it seems like you got a large dose of sensory detail, you only got a tiny fraction. You only became aware of the details your brain determined were the most important.

You missed all the ants and bugs on the sidewalk, or you missed thousands of individual rocks and pebbles. There’s no way you noticed every blade of grass or every bird that flew within your field of view.

Heck, you even overlooked an average human who happened to be strolling through the park. And even if you did notice them, you quickly deemed them unimportant. Not a threat, not a friend, sort of a nobody.

They may have briefly been in your field of view, but they never triggered your RAS…

The bottom line is:

There’s no way our brains can process even a fraction of available information. So it filters – a lot of it.

It only focuses on the data we perceive as most important. That way, we can make decisions and take action without constant sensory overload.

Faces In A Crowd

For example, if you walk through a crowd at a large sporting event, you’ll pass by thousands of unfamiliar faces. You’re lucky if you can recall any of them even a few seconds later. That’s the RAS doing its job.

Yes, your field of vision “your eyes” saw each face, but the RAS filtered them out of your conscious memory. Why? Because those faces didn’t rise to the level of needing a response.

But when you see a friend at the event – a familiar face – it’s a worthwhile stimulus. It immediately bypasses the RAS filter. Your brain has a stored memory of this face – it’s seeing someone you know – you better respond or you’ll be a jerk!

And it’s not just faces either, interesting or odd features also form memories.

For example – someone who’s extremely tall or short you may recall with vivid detail later. Or someone with purple-colored hair. Or a person wearing a funny shirt, or even someone with very strong cologne.

Even interesting-looking animals or buildings tend to stick out in our consciousness. But it requires something, unique, or different to rise above the level of filtration.

Before vs. After A Purchase

Have you ever purchased something – new thinking you were one of the only people to own such a device? Then after you buy, you start noticing so many others NOW have it as well.

Before you bought the item (or desired the item), your RAS was filtering it out. You were not aware of it, so it was not important, and the RAS system glossed over it.

Once you bought it (or wanted it), you started to “see it.”

This is typical of new vehicle purchases. The day after you buy a new car, it seems like there are so many more people driving the same model as you.

This is not true, you just “notice” these models now, while before, you didn’t notice them. Sure you SAW them but you didn’t NOTICE them. See the difference?

So when following the Gray Man concept – you can use this human quirk to reduce attention. You do this by managing your actions, your movements, and your physical appearance.

This allows you to slip past others staying well below their RAS threshold. Never forming much of a conscious recognition or memory of your presence.

Think of it as a superpower.  A way to hide in plain sight. It’s like a cloak of invisibility.

While it’s not TRULY the same as being invisible, it can come awfully close in certain situations!

For those of us who prepare, it allows us to move about safely without giving away how well-prepared we are.

The secret to blending in – is to appear as “normal”, “average” and “non-threatening” as possible. This includes how you dress, how you interact with others, even how you move.

So the first step in becoming a gray man is to establish a baseline. 

Determine what’s the appropriate dress code, mannerisms, and ways of acting for each situation. There are different baselines in a formal office setting vs. an outdoor summer concert vs. a tropical beach.

For example, many survivalists love the idea of wearing tactical pants and tactical backpacks (and some even go with a ghillie suit). And why not? This type of survival attire has some significant survival advantages. And while they help hide you in the wilderness – they get noticed in the city.

They draw unwanted attention in urban environments.

That’s why colors and patterns that “match the masses” are better to remain discrete in crowds.

Popular Gray Man Gear

So before we move on to specific Gray Man tactics. I want to share what gray man gear looks like.

Note: Blending in is a relative skill.

There is no single answer blending in everywhere. For example; clothes used to blend into a U.S based coffee shop might stick out like a sore thumb at a Western Rodeo Conference.

The same goes for different cultures and different countries. You’ll have to figure out what the “average” or “typical” is like in the location you want to blend in…

For the following gray man gear suggestions – we’re targeting the streets of a typical modern US city.

Gray-Man Pants

Under Armour Covert Tactical Pants – Perfectly Boring!

We’ve mentioned some of these options in the past, such as these tactical “gray man” pants.

These “covert tactical pants” are gray and they look just plain average. Perfect! 

Which is exactly what you want to blend in.

And they’re comfortable, durable, breathable, and stretchy – what’s not to like.

Gray-Man Backpack

An Incognito Backpack That Includes Conceal Carry Pouch

If you’re ever caught in an emergency in an urban environment – you’ll want a pack that blends in.

For example, carry a streamlined backpack or messenger bag, like this one.

My favorite part of this bag is its quick access bottom compartment for internal concealed carry.

It doesn’t have very many external pockets and the color is perfectly forgettable. Exactly what you want to stay under the radar.

Here an article where we go over 12 more everyday carry bags.

Gray-Man Jacket

Simple Looking Jacket With Surprising Tactical Features

Speaking of outer layers, there are even gray man-approved jackets.

This one includes both discrete storage and tactical features (even dedicated CCW pockets).

Plus, they have a modern clean-cut look.

Gray-Man Accessories

Leave the tactical survival belt with extra pockets and a large survival knife or machete at home. Or at least keep it out of sight under a jacket or in your pack.

Instead, wear a neck knife under your new jacket. The best ones leave virtually zero imprints.

Gray-Man LockPicking Tools

One of the best ways to remain hidden is to stay out of sight. So there’s no better way to travel than by accessing locked buildings and warehouses.

The Ultimate Lockpicking Toolset

The Ultimate Lockpicking Toolset

If they’re locked, you know it won’t be crowded inside. So you can move undetected throughout a city from build to building IF you know how to pick locks and carry the proper set of lockpicking tools.

Human Features Matter

Shaved heads (women) or very long hair (men), will stand out in someone’s mind far more than a “generic” haircut.

If you’re particularly tall or short, fat or thin, it may be harder to pass by unnoticed no matter what else you do.

If you fit any of these categories, think about how you could reduce the appearance of that trait.

The average is the name of the game for the gray man.

This applies to your mannerisms as well.

Gray-Man Mannerisms

While in a crowd, pay attention to social cues. If everyone else is engaging in small talk, make sure you do as well to avoid appearing standoffish.

Be prepared to discuss normal topics like the weather or local events. But keep away from any controversial subjects like politics or religion.

Also too much or too little eye contact can also be memorable.

If you smoke, avoid it unless you’d be noticeable NOT doing it – like visiting a smoking area without a cigarette.

Keep a constant tab on your situational awareness. But do so with subtle observations, not constantly scanning the crowd and the room.

Gray Man Mistakes

The biggest mistake people make in trying to be a “gray man” is to look like this image below:

Sorry but that person looks like they have something to hide…

Hiding in plain sight doesn’t mean actually looking like your hiding. It’s looking like you have nothing to hide – a big difference!

Wearing a hoodie jacket is fine but don’t put the hoodie up (unless everyone else is) – otherwise, it looks suspicious. Also, don’t hunker your shoulders in an extreme effort to look small. People notice when someone looks like this.

Instead, model the look, feel, and behavior of the average person where you are. Not too confident, but also not sad. Avoid walking too fast or too slow.

Looking overly sneaky has the opposite effect- people notice.

Gray Man Disguises For Access

For the most part, we’re discussing being an everyday gray man. Someone who goes about their business all over town.

But what if you want to be a gray man at a specific event, time, or place? Then you might want to put on a gray man disguise…

There are people in the world who naturally go unnoticed.

Janitors, homeless, and security personnel are prime examples.


If you want access to an event or inside a restricted building, you might slip past if you look like a janitor.

Janitors move throughout buildings with ease and without a second glance. Janitors walk around – cleaning and fixing things. It’s not abnormal behavior.


If you want to observe something outside on the city streets, the homeless are often ignored.

Especially if you’re an average, sleepy homeless. You need to look the part but act like a passive homeless person – not an aggressive one.

So, no threatening people passing by, and no talking to yourself. Just find a seat next to a dumpster and blend into the background of the city…

Security Guards

Finally, security guards, look like they have authority and can go anywhere they want. The trick is to avoid other security personnel, they might call you out as a fraud.

The other issue with security guards is in the event of an emergency, you’re the guy who everyone expects to help.

So while security guards have unfettered access, and blend in during times of calm, not so much in times of chaos or an all-out riot.

During a crisis, everyone becomes hyper-aware.

This is the brain’s way of sorting all the incoming information. It’s trying to access it’s best options that could help in a fight or flight response.

Even subconsciously, people notice things that would have otherwise gone undetected in emergencies.

For example:

Someone who doesn’t reflexively gasp at an explosion likely had prior knowledge of the event.

Also, moving (especially running) against the crowd is a sure way to draw attention. To blend in, always work with the flow of traffic, breaking away only when doing so won’t be noticeable.

Know your exits, but remember anyone who darts for the closest exit first in an emergency will stand out. Wait for others to move first if you want to stay under the radar.

After an emergency, there are two types of people whose attention you would be best off avoiding:

  1. Those in need of a leader.
  2. Those in search of a victim.

Those In Need Of A Leader

The vast majority of people fall into the first group, those in need of a leader.

These are people who failed to prepare for an emergency and have little in the way of skills or supplies. They need help to navigate the situation.

They’ll instinctively seek out anyone who can provide them with answers and security.

If you want to remain unnoticed, don’t become a hero. Avoid becoming the unintentional leader of the unskilled and unprepared masses. These new followers will limit your resources, time, energy, and options.

Unfortunately, not helping may go against your nature. Is hiding your abilities the moral thing to do? That’s your call. But if you do, you will no longer blend in. You’ll quickly become the center of attention.

Those In Search Of A Victim

The second group, those in search of a victim, is generally smaller but can be far more dangerous.

These are predators and opportunists who may recognize your abilities. And if they do, they may take your supplies by force or make you do their bidding.

Avoiding the attention of these bad dudes can be a matter of life and death. So it’s critical to learn how to identify them quickly in a crowd.

So how do you blend into a crowd after an emergency situation?

Essentially, you’ll want to take whatever emotion the crowd is showing and mimic it at a bit lower intensity.

If the crowd is panicking and unruly, don’t remain calm. Even if it’s an act, a little fake panic will help you go unnoticed.

If they’re dazed and confused by the situation, a confident person will stand out. Go about your business with a shuffling, hesitant air and you’ll find no one pays attention to you.

Be aware of your surroundings, but try to be subtle about it. People notice someone with their head on a swivel.

Dense Crowd


If you really want to hone your ability to hide in plain sight, you need to figure out what makes people memorable.

One of the best ways to learn is to practice the art of observation.

Visit a busy public area – parks, shopping centers, coffee shops, are all great options.

As people walk by, make a point of finding one standout trait about each person. Try to think of the first thing that caught your attention when you looked at them.

Do they have an old walk? A big nose? Are they wearing too much makeup or perfume?

Anything you’d use to point them out to a friend can be a memorable feature to identify them later.

These are the kinds of things you want to avoid or mitigate in your own public appearance. Ideally, you want to have zero noticeable characteristics. Nothing that can catch someone’s unwanted attention.

While you’re observing the crowd, keep an eye out for the person who *doesn’t* draw your attention. This is harder than it seems.

But if you wait long enough, you’ll eventually come across a few of these “generic” humans. You’ll know it when you struggle to come up with an identifying characteristic.

Once you notice someone like this, take note of how they dress and how they move. If they interact with other people, how do they behave?

Pay attention to their body language and how they speak. These are the traits you’re trying to mimic.

Learn what draws attention and what goes unnoticed – and how that changes from one setting to another.

This will allow you to perfect your own “gray man camouflage”. To blend into any situation and melt away unnoticed. To adapt and vanish as conditions change.

In time, you’ll become near invisible to the casual observer.
