What does IWB stand for?

IWB stands for Inside-the-Waistband. It refers to a holster worn inside your pants, between your body and your waistband, to conceal a firearm under everyday clothing.

What does IWB mean in holsters?

IWB means the holster is designed to sit inside your waistband — inside your pants — rather than outside them. This positions the gun against your body where it is hidden under a shirt or jacket.

How do you wear an IWB holster?

Clip or loop the holster over your waistband, position it at your preferred carry position (3–4 o'clock strong side or 1–2 o'clock appendix are most common), thread a stiff gun belt through the loops, and tuck your shirt over the grip. Ride height and cant can be adjusted with a screwdriver on most Kydex holsters.

What is the most comfortable IWB holster position?

Strong-side at 3–4 o'clock is the most comfortable position for most people — the gun sits on your hip where clothing naturally drapes over it. Appendix carry (1–2 o'clock) is preferred by many for faster draw and better concealment when seated, but takes more adjustment to get comfortable.

What is the difference between IWB and OWB holsters?

IWB holsters sit inside your pants for concealment. OWB (Outside-the-Waistband) holsters clip outside your pants on the belt — they are easier to put on and generally more comfortable, but require a cover garment to conceal.

What is an AIWB holster?

AIWB stands for Appendix Inside-the-Waistband. It is an IWB holster worn at the front of the body (1–2 o'clock position, near the appendix) rather than the side or rear. AIWB holsters often include a claw or wedge to push the grip into the body and reduce printing.

IWB stands for Inside-the-Waistband. An IWB holster is worn inside your pants, positioned between your body and your waistband, so the firearm stays completely hidden under a shirt or jacket. It is the most popular method of concealed carry in the United States.

What Does IWB Mean?

IWB is short for Inside-the-Waistband. The holster clips or loops over your belt and the holster body — and the gun — sits inside your pants against your body. From the outside, all that is visible is the clip on your waistband and a slight belt bulge. Under any loose shirt, nothing shows at all.

The opposite of IWB is OWB (Outside-the-Waistband) — a holster that mounts on the outside of your pants. OWB is more comfortable and faster to put on, but requires a jacket or cover garment to conceal. IWB conceals under a t-shirt.

AIWB (Appendix Inside-the-Waistband) is a variant of IWB where the holster is worn at the front of the body (1–2 o'clock) instead of the side. See our full IWB vs AIWB guide if you are deciding between the two.

How to Wear an IWB Holster

Choose your position — start at 3–4 o'clock (strong side hip) if you are new to IWB
Thread a stiff gun belt through your pants loops before clipping the holster — a dress belt will sag and make everything uncomfortable. Our gun belt guide covers what to look for.
Clip or loop the holster over your waistband at your chosen position
Holster your unloaded firearm and adjust ride height — the grip should be fully accessible above the waistband with your shirt untucked
Adjust the cant (angle) — most people find 10–15° of forward cant comfortable for a strong-side draw
Dress over it — tuck your shirt over the grip for full concealment

IWB Carry Positions Explained

Where you position the holster on your waistline changes everything — comfort, concealment, and draw speed. Here are the main options:

Position	Clock Location	Best For
Appendix (AIWB)	1–2 o'clock	Fast draw, seated concealment
Strong side	3 o'clock	Natural draw, all-day comfort
Behind the hip	4–5 o'clock	Deep concealment when standing
Kidney	5–6 o'clock	Larger builds, seated comfort

Appendix (1–2 o'clock): The gun is at the front of your body. Faster to draw seated, excellent concealment when properly set up with a claw and wedge. Requires a holster built for appendix use. Read our appendix carry guide before committing to this position.

Strong side (3 o'clock): The gun sits on your dominant hip, directly aligned with your hand at rest. The most natural draw stroke and the most comfortable for extended wear. Where most people start, and where many stay.

Behind the hip (4–5 o'clock): Slightly behind the hip bone, this position conceals the grip better when standing but can be harder to reach while seated or driving. Our full breakdown of all positions is in the IWB carry positions clock guide.

IWB vs OWB: Which Should You Choose?

Feature	IWB	OWB
Concealment	Excellent — under a t-shirt	Requires cover garment
Comfort	Good with proper setup	Generally more comfortable
Draw speed	Slightly slower (gun sits lower)	Faster — gun is more accessible
Setup time	More adjustment required	Simple
Best for	Everyday concealed carry	Range, open carry, or cover garment carry

For most people doing everyday concealed carry, IWB is the right choice. For range use, open carry states, or when you always wear a jacket, OWB may be more practical.

What Makes a Good IWB Holster

Not all IWB holsters are equal. These are the features that matter:

1. Gun-Specific Molding

The holster must be molded to your exact firearm — not "fits Glock" or "fits most pistols." Retention, trigger safety, and consistent draw all depend on a shell that fits your specific model. Browse our model-specific guides: Glock 19, Glock 17, Glock 43, Glock 43X, Glock 45, Glock 26.

2. Full Trigger Guard Coverage

Nothing should be able to contact the trigger while the gun is holstered — no fabric, no drawstrings, no fingers. This is the single most important safety feature of any holster. See our reholstering safely guide.

3. Adjustable Cant and Ride Height

Most shooters need to tune the angle and depth of the holster to their body and carry position. Look for a holster with at least two adjustment screws. Our cant and ride height guide shows exactly how to dial this in.

4. Sweat Shield

A full-length sweat shield keeps the metal slide off your skin and your sweat off the gun — both matters over a long carry day.

5. Audible Retention Click

You should hear and feel the gun seat into the holster. A holster that lets the gun slide in silently gives you no confirmation it is retained.

6. A Real Gun Belt

The most common complaint about IWB comfort is actually a floppy belt. An IWB holster on a cheap dress belt will sag, rotate, and dig into your side. A dedicated gun belt — rigid enough to support the weight without flexing — fixes most "the holster is uncomfortable" problems.

Kydex vs Leather for IWB Holsters

Kydex is the dominant material for IWB holsters today. It is rigid, moisture-resistant, holds its shape indefinitely, and gives a consistent draw every time. It requires no break-in period.

Leather is softer and conforms to your body over time, which some carriers find more comfortable. It requires a break-in period and can soften to the point of losing retention if it gets wet repeatedly.

Hybrid holsters combine a leather or neoprene backing (against your skin) with a Kydex shell (holding the gun). These are popular for all-day comfort, especially for larger builds.

Comfort Tips for IWB Carry

IWB carry does take adjustment. Here is what makes the biggest difference:

Buy pants one size up in the waist — the holster and gun add approximately 1 inch of waistband thickness
Use a stiff gun belt — the single biggest comfort upgrade most new carriers can make
Start with 2–3 hour sessions and build up — your body adapts to the pressure over days and weeks
Adjust ride height so the grip clears your waistband without the muzzle digging into your thigh
Add a wedge if the grip prints — a foam wedge behind the muzzle tilts the grip into your body
Try different positions — what is comfortable for one person may not work for another body type

Who Is an IWB Holster For?

IWB holsters work for most concealed carriers, but they are the best fit if you:

Want to conceal under everyday clothing without a jacket
Carry in a warm climate where cover garments are impractical
Work in an environment where printing must be avoided
Carry a compact or subcompact pistol (though full-size guns like the Glock 17 carry fine IWB with the right setup)
