You see them everywhere—loose, light blue denim that looks like it came straight from a 1990s barbecue. You wonder if this is a legitimate fashion trend or just people giving up on style.

Dad jeans¹ are a specific style of denim characterized by a relaxed fit, a straight leg, and a medium-to-high rise. They are typically light wash (stone wash), 100% cotton with no stretch, and sit loosely on the hips and thighs, prioritizing comfort and utility over a fitted silhouette.

As a denim manufacturer with 20 years in the game, I look at "dad jeans" and see a return to basics. For a long time, everything was skinny, stretchy, and tight. Dad jeans are the opposite. They are what we call "anti-fit." They don't hug your body. They hang off your body.

While some people in the fashion world turn their noses up at the "relaxed fit²" silhouette, there is a reason this shape has survived for decades. It is honest. It is durable. It is comfortable.

What Are Dad Jeans vs Mom Jeans?

People often confuse these two retro styles. They both look vintage, they both have high waists, but the engineering of the pattern is completely different.

The main difference is the leg shape and the fit through the hips. Mom jeans have a high waist with a tapered leg that gets narrower at the ankle (carrot shape), while dad jeans have a straighter, boxier leg that stays loose from the hip down to the shoe.

Let's dive deeper into the pattern making. When we cut Mom Jeans, we are thinking about curves. The waist is high to cinch the stomach, the hips are rounded to accommodate a woman's shape, and the leg tapers down. It draws attention to the waist and the backside.

Dad Jeans, on the other hand, are rectangular. We cut the fabric to be boxy. The rise (the distance from the crotch to the waist) is medium or high, but there is no attempt to "shape" the rear end. It is just a straight line down. In the factory, we call this a "stovepipe" leg.

Think of it this way: Mom jeans are trying to be flattering in a retro way. Dad jeans are not trying to be flattering at all; they are trying to be comfortable. Dad jeans usually have a zipper fly, while vintage mom jeans often have a long zipper or buttons. The dad jean leg opening is wide, perfect for covering a pair of chunky white sneakers.

What Are Dad Jeans Made Of?

You might think denim is denim, but the material used for dad jeans is very specific. It is not the soft, stretchy stuff you find in skinny jeans.

Dad jeans are almost always made of 100% heavyweight cotton denim without any elastane or spandex. They are built for durability and structure, often featuring a "stone wash" or light blue finish that softens the thick fabric without compromising its toughness.

In my factory, we have different rolls of fabric for different clients. When a client wants a dad jean, I go to the 100% cotton³ section. We avoid "stretch" at all costs.

Why? Because the dad jean needs to hold its own shape. If you use soft, stretchy fabric for a relaxed fit, it just looks like sweatpants. It drapes too much. Real dad jeans need to stand away from the leg.

This connects directly to durability. Brands like Rustler or LL Bean are famous for this. They use denim that feels like armor. I have seen Rustler pants that are tougher than almost any designer jean on the market today. They are built for working in the yard, not for a runway.

If budget isn't an issue, some "dads" go for Iron Heart⁴ jeans. This is the extreme end of the spectrum. Iron Heart uses incredibly heavy 21oz denim. It is overkill for most people, but it fits the "dad" philosophy: buy one thing that lasts forever. The lack of stretch means you have to break them in, but once you do, they are yours for life.

What Are Considered Dad Jeans?

You walk into a store—what exactly are you looking for? Is it a brand? A fit? Or just a vibe?

Dad jeans are typically defined by models like the Levi's 550⁵ or brands like Kirkland (Costco), Rustler, and Duluth Trading Co. They feature a relaxed fit, a light wash, and are often paired with practical items like chunky white sneakers or plaid shirts.

The quintessential example is the Levi's 550. This is a "relaxed fit" jean. In the fashion world, we often say relaxed fit is a "big no-no" if you want to look sharp. It creates a lot of extra fabric around the thighs and knees. But that is exactly what makes a jean a "dad jean."

If you go to Costco and pick up a pair of Kirkland Signature⁶ jeans, you are buying the ultimate dad jean. They are generic, sturdy, and cheap.

They aren't trying to impress anyone. Duluth Trading Co. is another great example. I have had the same experience as many of you—their pants are incredibly durable. They add gussets (extra fabric in the crotch) for movement. This is engineering for function, not form.

The "look" is completed by the accessories. You don't wear dad jeans with Chelsea boots. You wear them with New Balance or Reeboks (the white ones). You wear them with a button-down short-sleeve plaid shirt. It is a uniform of suburban practicality.

What's the Difference Between Dad Jeans and Regular Jeans?

Is "dad jean" just a nickname, or is there a technical difference in how they are cut?

The main difference is that regular jeans usually follow the line of the leg with a standard fit, whereas dad jeans add extra room in the "seat" (butt) and thigh area. Dad jeans are cut with a "relaxed" pattern that does not touch the skin, creating a looser, less defined silhouette.

Let's look at the "Regular Fit" versus the "Dad Fit" (Relaxed).
If you are slim, a regular fit jean will look clean. It follows your lines.
A dad jean takes that pattern and adds maybe 2 inches of circumference to the thigh and 1 inch to the rise.

This creates what we call "diaper butt" if you aren't careful. Because there is so much extra fabric in the seat, it can sag. Regular jeans are designed to sit closer to the body. Dad jeans are designed so you can squat down to fix a lawnmower without the fabric pulling tight.

My advice? If you are carrying a little extra weight, the relaxed fit (dad jean) is comfortable. But be careful—it can make you look bigger than you are. If you are not "fat," stick to a slim or regular straight cut. You can still get the durable, thick denim without the baggy silhouette that makes you look shapeless.

Why Are They Called Dad Jeans?

It seems like a strange name for a piece of clothing. Why do we associate a specific cut of pants with fatherhood?

They are called dad jeans because they became the default uniform for middle-aged American fathers in the 1990s and 2000s. The term was popularized as a slightly derogatory label for uncool, practical denim, most famously associated with figures like Barack Obama.

The term really took off when President Obama threw out the first pitch at an All-Star Game in 2009 wearing these loose, light-wash jeans. The media went crazy. They called them "Dad Jeans." It was meant to say: "This guy has given up on looking cool."

But here is the irony. In the fashion cycle, "uncool" eventually becomes "cool."
The dad jean represents a rejection of trends. A dad doesn't care if skinny jeans are in style; he wants pants that fit. He goes to LL Bean because he knows the quality is good. He goes to Costco because the price is right.

This attitude—prioritizing function and comfort over looks—is actually very attractive to the younger generation now. They call it "Normcore⁷." So, while the name comes from suburban fathers who just wanted to be comfortable, the style has been adopted by people who admire that effortless, "I don't care" attitude.

Conclusion

Dad jeans are light-wash, relaxed-fit denim that prioritize comfort and durability over fashion. Whether you buy durable pairs from Rustler and LL Bean or high-end versions from Iron Heart, they are a statement of practical confidence.
