Jeggings vs leggings: which one you actually want
Key takeaways
- Both are knits. The difference is how far each pretends to be denim.
- Above about 12 percent elastane a knit clings like a legging; jeggings usually sit lower and hold a shape.
- A jegging has jean details on a knit: colour, pocket stitching, sometimes a mock fly.
- Opacity is decided by fabric weight and knit density, not by the name.
What each one is made of
A legging is a knitted tube, usually a nylon or polyester blend with a high elastane content, sewn to a waistband. At around 12 percent elastane and above the fabric behaves like a second skin: it stretches in every direction and returns, and it follows the body exactly. A jegging is the same construction with a denim look: the yarn is dyed to read as indigo, pockets and seams are stitched or printed on, and the elastane is often lower so the fabric holds a leg shape rather than mapping it.

How they behave differently
Leggings move with you and layer under anything; they also show every line of what is under them and, in a light or thin knit, go translucent when stretched over the seat. Jeggings hold a shape at the thigh and knee and read as jeans from a short distance, which is the point, but they are still a knit and do not have the structure of a woven. Neither has real pockets you can rely on unless the listing says the pockets are functional.
Opacity is not decided by the name
Whether a knit stays opaque when you bend depends on the weight of the fabric and how tightly it is knitted, not on whether it is called a legging or a jegging. A heavy, dense knit in either stays opaque; a light one in either goes see-through at the seat. Our product pages record opacity where it has been tested and read "Not measured" where it has not.
Which to choose
If you want to move, exercise, layer or wear a long top, leggings do it better. If you want to read as wearing jeans at a distance and still have the comfort of a knit, jeggings do that and leggings cannot. If you want the look of jeans with real pockets and a working fly, neither is the answer; a pull-on jean in a woven stretch denim is, and it is a different garment again.
What to check on the listing
Three things: the elastane percentage, which tells you cling or shape; whether the pockets are functional, which most jeggings are honest about; and the waistband depth, because a knit at any elastane level needs a band at least 2 inches deep to stay up without rolling. Everything else is styling.

Frequently asked questions
- Are jeggings just leggings that look like jeans?
- Mostly. Both are knits. A jegging adds denim colour and jean details and usually sits lower on the elastane scale, so it holds a leg shape rather than clinging.
- Which is more opaque?
- Neither by name. Opacity depends on fabric weight and knit density. A heavy dense knit in either stays opaque; a light one in either goes see-through at the seat.
- Do jeggings have real pockets?
- Sometimes. Many have stitched or printed pockets for the look. The listing usually says whether they are functional; if it does not, assume they are not.
