Honestly, sleepwear is one of those things we usually overthink or completely ignore. We either spend way too much on silk sets that feel amazing for twenty minutes before they get static-y and weird, or we just wear a t-shirt from a 5K run back in 2012. But Gap sleepwear for women has carved out this strange, permanent middle ground. It’s not "luxury," but it’s also not the cheap stuff you find in a plastic bag at a big-box pharmacy.
People buy it because it’s predictable. In a world where every online brand is trying to "disrupt" pajamas with eucalyptus fibers or cooling minerals, Gap just makes cotton. Good cotton.
Most of us have a pair of their modal joggers that have survived three house moves and a dozen breakups. Why? Because the fabric doesn’t pill after the third wash. It's actually kind of impressive how they’ve maintained a grip on the market when brands like Skims or Adore Me are constantly shouting for attention.
What People Get Wrong About the Fabrics
There’s a huge misconception that all pajamas are basically the same once you get past the price tag. They aren’t. When you look at Gap’s lineup, you’re mostly looking at three things: Pure Body, Dreamwell, and their classic poplin.
The Pure Body line is where they use Lenzing™ Tencel™ modal. If you aren't a textile nerd, just know that modal comes from beech trees. It’s semi-synthetic but breathes better than pure polyester. It’s heavy, too. That’s the secret. Thin pajamas twist around your legs while you sleep. Gap’s modal has enough weight to stay put, which is probably why it's been a bestseller for literally decades.
Then there’s the poplin.

Poplin is polarizing. Some people think it feels like sleeping in a dress shirt. It’s crisp. It’s 100% cotton. If you’re a hot sleeper, poplin is actually your best friend because it doesn't cling to your skin when you start to overheat. Gap usually does these in those classic menswear stripes. It's a look. It’s very "I have my life together even though I’m just eating cereal at 11 PM."
The "Dreamwell" Factor
A few years ago, Gap leaned hard into the Dreamwell collection. It was their answer to the boutique lounge movement. These are usually satin-finish or very soft brushed jerseys. They feel a bit more elevated. You could probably wear the Dreamwell top with jeans and no one would know you just woke up.
The Sizing Reality Check
Let’s talk about the fit because this is where people get frustrated. Gap is notorious for "vanity sizing." If you are a Medium at a high-end boutique, you are almost certainly a Small—or even an Extra Small—at Gap.
Their sleepwear is cut for comfort. That means wide leg openings, dropped shoulders, and elastic waists that don't dig in. If you want that sleek, "Instagrammable" pajama look, you actually have to size down. If you want to actually be able to breathe while eating pizza on the couch, stay true to size.
They also offer "Tall" and "Petite" lengths. This is a big deal. For women over 5'9", finding pajama pants that don't look like high-waters is an eternal struggle. Gap is one of the few places where you can get a 33-inch inseam on a pair of pajama bottoms without paying a custom tailor.

Why Gap Sleepwear for Women Actually Lasts
Sustainability is a buzzword every brand throws around, but true sustainability is just not throwing stuff away. Gap’s construction is surprisingly robust. They use reinforced seams on their leggings and joggers.
I’ve seen reports from long-time customers who still have Gap Body pieces from the early 2000s. The elastic might give out eventually, but the fabric itself doesn't thin out until you've washed it hundreds of times. That’s the "Value Per Wear" math. If you buy a $50 set and wear it twice a week for four years, you’re paying pennies.
Comparisons that Matter
How does it stack up against others?
- VS. Target (Stars Above): Target is cheaper, sure. But the Stars Above line tends to lose its shape. The knees bag out after one night. Gap’s jersey has better "recovery"—it snaps back.
- VS. Eberjey: Eberjey is the gold standard for soft pajamas, but they are $120+. Gap’s modal is about 80% as soft for 30% of the price.
- VS. Old Navy: They are owned by the same company, but the quality floor is different. Old Navy sleepwear is often thinner and uses more synthetic blends that can feel "sweaty" at night.
The Seasonal Trap
You have to be careful with the flannel.
Every November, Gap releases a mountain of plaid flannel. It’s iconic. It’s festive. But be warned: Gap’s flannel is thick. If you live in a modern apartment with good heating, you will bake in these. They are designed for drafty houses or mid-winter in Vermont.

Also, the flannel doesn't stretch. At all. While the modal and jersey pieces are very forgiving, the flannel sets require you to get the sizing exactly right or you’ll feel restricted when you roll over in bed.
Wash and Care Truths
Stop drying your pajamas on "High." Seriously.
Even though Gap sleepwear is durable, the heat destroys the elastic fibers (elastane or spandex) in the waistbands. If you want your sets to last five years instead of two, wash them on cold and tumble dry on low. Or, if you’re feeling productive, hang dry the modal pieces. They dry fast anyway.
Practical Steps for Building a Sleep Wardrobe
You don't need twenty sets. You really don't. A functional "sleep capsule" using Gap pieces usually looks like this:
- Two Modal Sets: These are your workhorses. One long sleeve for winter, one short sleeve or tank for summer.
- One Cotton Poplin Set: For those nights when you’re feeling a bit overheated or just want to feel "crisp."
- The "Big Shirt": Gap often sells oversized sleep shirts. These are underrated for Sunday mornings.
Check the "Gap Factory" site too, but look closely at the fabric labels. Sometimes the Factory version uses a higher percentage of polyester to keep costs down, which defeats the purpose of buying for breathability. Stick to the main line if you want the Tencel blends.
The best time to buy is always the "Big Gap Sale" cycles. Never pay full price. Gap runs 40% to 50% off sales almost every other week. If you see a pajama set for $70, just wait seven days. It’ll be $38 soon enough.
Invest in the modal joggers first. They are the "gateway drug" of the collection. Once you realize you can look decent enough to answer the door for a delivery driver while feeling like you're wearing a cloud, there's no going back to those old high school gym shorts. Focus on the fabric weight and the inseam length, and you'll end up with a drawer full of stuff you actually use instead of just "pretty" sets that sit in the back of the closet.
