The short answer
Pick the fabric for the bedroom, not for the photo. If your December nights stay mild and the heat rarely runs, start with bamboo christmas pajamas or a cotton set. If you live where the furnace runs all night, or the guest room at Grandma's sits over a cold garage, fleece earns its place. Satin is the dressy choice for adults, and a short-sleeve top is the fix for the one person in every family who sleeps hot. Fabric can also decide how far your sizes go, so check both before you fall for a print. PatPat sells every set named here, and nothing below was wear-tested; the warmth judgments come from reading each listing's fabric line.
| Your nights look like this | Start with | Keep as the backup |
|---|---|---|
| Mild winter, heat off or barely on (much of Florida, Southern California, South Texas) | Bamboo viscose or cotton, long sleeves | A short-sleeve top for the warm sleeper |
| Heated home, bedroom roughly 65–70°F | Regular polyester stretch knit, cotton or bamboo viscose | Fleece for the person who is always cold |
| Cold winter, heat turned down at night (Northeast, Midwest, Canada) | Polyester fleece two-piece | Coral fleece onesie for mornings and lounging |
| Mixed household: one runs hot, one runs cold | Two fabrics in the same color family | Layer a cold sleeper rather than overdress everyone |

Before You Choose a Christmas Pajama Fabric, Take Your Bedroom's Temperature
Most families pick a fabric by what they think their house feels like. An inexpensive thermometer on the nightstand for three nights will tell you more. Read it twice: once when you go to bed and once when the first person wakes up. The gap between those two numbers is what your Christmas pajamas actually have to handle.
The Sleep Foundation puts a comfortable adult bedroom at roughly 65 to 68°F. Use that as a reference point, not a target you must hit. What matters for buying pajamas is which side of it your house falls on:
- Above about 70°F at 3 a.m.: fleece will likely be too much for most adults. Look at bamboo viscose, cotton or a regular polyester knit, and consider a short-sleeve top.
- Roughly 65 to 70°F: almost any fabric works, so let the sizes and the print decide. Keep fleece for the person who always asks for another blanket.
- Below about 65°F, or a big drop overnight: this is fleece territory, especially for anyone who kicks off the covers and then wakes up cold.
Canadian readers: 65°F is about 18°C and 70°F is about 21°C.
Two other things change the reading. Bedding counts: a family that sleeps under a heavy comforter can wear lighter pajamas than one that uses a thin quilt. And the room is not always your room. If Christmas Eve means sleeping at a relative's house, take the reading there if you can, or ask what the thermostat is set to overnight. A guest room over a garage or at the end of a long hall can run several degrees colder than the rest of the house.
Babies are a separate question with their own rules, covered later in this guide and in more depth in our bamboo vs. fleece baby sleepwear guide.
Best Christmas Pajama Fabrics for Warm-Winter States
In a mild climate the risk is waking up sweaty, not cold, so go light first. Here is how the three lighter options in PatPat's Christmas range compare, using what each listing says about itself.
Bamboo viscose
The green Christmas tree set lists 93% viscose from bamboo and 7% spandex, with a 95/5 blend on the trim. The red gingerbread set lists the same 93/7 main fabric. Both descriptions call the cloth soft, stretchy and breathable. Under FTC guidance on bamboo textiles, fiber like this is a rayon and should be called something like "rayon made from bamboo," so a label that says only "bamboo" with no rayon or viscose is a reason to ask questions.
Who it suits: warm sleepers who still want long sleeves in the family photo, and anyone who dislikes the slightly slick feel some polyester knits have.
One caution on titles. A third listing in the range has "Bamboo" in its title while its description gives a cotton composition. Where the title and the description disagree, we treat the description as the record and ask before buying. We left that set out of this guide.
Cotton
The blue Christmas tree set lists 91% cotton and 9% spandex, and its description calls the fabric lightweight and moisture-wicking. The cream gingerbread and tree set lists 95% cotton and 5% spandex and calls it breathable. Cotton suits people who simply prefer a natural fiber against the skin. Both of these sets use a different kids' scale from most PatPat Christmas pajamas (2T through 5T, then 6, 8 and 10), so check the chart before you assume a 6-7Y fits.
Short sleeves
Short sleeve christmas pajamas solve a narrower problem: the house is warm, but the family still wants long pants in the photo. The festive dog set pairs a short-sleeve top with full-length pants for adults and kids, in a 95% polyester, 5% spandex knit. The navy reindeer glow-in-the-dark set does the same. Neither is a lightweight fabric; the cooler feel comes from bare forearms, which is often enough for someone who runs just a little warm.
For kids only, the 3-piece bamboo sets go further: a short-sleeve top, long pants and shorts in one package, listed as 95% bamboo fiber and 5% spandex, in sizes 2T to 12. On a warm night a child can swap the pants for the shorts and still match the top. These are labeled "Wear Snug-fitting, Not Flame Resistant," which matters for sizing (see the kids' section below).

Fleece Christmas Pajamas for Cold Climates and Drafty Houses
If your bedroom drops below about 65°F overnight, start with fleece christmas pajamas. Almost all of PatPat's fleece is polyester, and it comes in two quite different forms.
Two-piece polyester fleece
The green gingerbread, green Santa and candy cane, red Christmas tree and Santa, and apricot reindeer and tree sets are all two-piece fleece. Their fabric notes describe a soft fleece knit, and several say it is brushed on both sides. A two-piece is easier than a onesie for children who are newly toilet trained, and you can take the top off a child who has warmed up without waking them fully.
Two of them stand out on sizes. The green gingerbread fleece ran from kids' 2Y to 12-13Y and adult S to 3XL when we read it, with baby sizes and a pet size. The red tree and Santa fleece reached 3XL in adults, but its kids' sizes in stock stopped at 8-9Y. If you have a tween, check that first.
Coral fleece onesies
Coral fleece is the long-pile, plush version. The white and gray reindeer onesie, the black candy cane onesie, the gray snowman onesie and the cream gingerbread onesie are all hooded one-pieces with a front zip. Their fabric notes describe plush coral fleece, and two of the descriptions call it "thick, warm" and "super warm." Of everything in the range, these sound warmest on paper.
That makes them better for a cold morning than a heated bedroom. In our judgment they suit a family that opens presents in a chilly living room, a cabin trip, or the person who never takes off their robe. For a child who sleeps hot, a coral fleece onesie under a comforter is likely to be too much, and the hood is one more layer you cannot easily remove. The reindeer onesie's listing also mentions a glow-in-the-dark print, which kids tend to enjoy at bedtime.

A note on reading titles. "Fleece" describes the brushed, napped surface of the cloth, and "polyester" describes the fiber, so two sets can share a fiber line and still feel very different. When warmth is the reason you are buying, read the title, the fabric line and the description together.
Satin, Modal and Regular Knit: Where Each Christmas Pajama Fabric Fits
Not every fabric choice is about temperature. Three more options fill the gaps.
Satin is for looks, mostly for grown-ups. The navy gingerbread and the Christmas village satin sets are 100% polyester with a smooth, lightweight finish and button-front collared tops. The listings call the feel silky and lightweight, and in our judgment satin is a style choice rather than a warm one. It reads well in photos and suits a couple who want something dressier than a printed knit. Both satin sets reached 3XL in adults when we read them. Note the care difference: the satin care notes say to line dry and skip fabric softener, while most knits say tumble dry low. Our Christmas pajama washing guide covers the rest.
Modal is a kids' option. The color-block kids' set is 93% modal and 7% spandex, labeled snug-fitting, in sizes 2T to 12. Modal is another cellulose fiber, smooth and stretchy. It is a single kids' set rather than a family listing, so they coordinate by color rather than matching a parent's print.
Regular polyester stretch knit is the default. Most of PatPat's family Christmas pajamas are a 94% to 96% polyester knit with spandex. They are not marketed as warm or cool, which is exactly why they work for a heated home in the 65 to 70°F range. If nobody in your family runs notably hot or cold, you can skip the fabric question and choose by print and sizes.
Woke Up Too Hot or Too Cold? Signs Your Christmas Pajamas Are the Wrong Weight
The first night in new pajamas is a test. Here is how to read the results the next morning and what to change, starting with the cheapest fix. These are practical observations, not medical advice, and they apply to adults and older kids.
| What you notice | Likely meaning | Try this first |
|---|---|---|
| Damp hair or a sweaty neck, covers kicked off | Too warm overall | Lighter bedding before lighter pajamas; then swap fleece for a knit, cotton or bamboo viscose |
| Woke up hot around 2 or 3 a.m., then fell asleep fine without covers | Pajamas fine, bedding too heavy for the overnight temperature | Keep the pajamas, use a lighter blanket |
| Woke up cold after kicking off the covers | Pajamas too light for a restless sleeper | Fleece two-piece, or add socks |
| Cold feet only | The rest is fine | Socks; many PatPat family sets include a pair of buffalo plaid socks |
| Hot upper body, cold legs | Sleeves are the problem | Short-sleeve top with long pants |
| Fine at night, cold on Christmas morning | Living room colder than bedroom | Keep the pajamas and add a coral fleece onesie or a robe for present-opening |
Two points are worth taking from this table. First, bedding is easier to change than pajamas, and changing it keeps everyone in the matching set. Second, a family can solve most of these problems by giving one person a different top or an extra layer rather than switching the whole family to a different fabric.
For babies, do not use this table. The AAP's guide to safe sleep says to dress a baby in only one layer more than you are wearing in the same environment, to keep blankets out of the sleep space, and not to put a hat on a baby indoors. If you are planning a baby's first Christmas outfit, our guide to baby's first Christmas pajamas covers sizes and sleep safety together.
How to Mix Fabrics in One Family and Still Look Matching
Each PatPat listing sells one print in one fabric, so if the family needs two fabrics, you are buying from two listings. That can still look matched in photos if you follow three rules.
- Match the color family before the print. A navy satin set and a cream coral fleece onesie both carry gingerbread, but they will read as two families in a photo. Two different gingerbread prints that both sit on dark green or both sit on red will read as one. Our three-color method explains how to check this.
- Split by role, not at random. Give the lighter fabric to the people who run hot (often adults under a comforter) and the warmer fabric to whoever runs cold. A common split is parents in a regular knit or bamboo viscose and kids in fleece, or the reverse in a house where the kids' rooms are warmer.
- Keep one element constant. Same print family, same color, or same sock: many family sets include buffalo plaid socks, and matching feet tie a mixed group together in a sofa photo.
Layering one cold sleeper without changing the set
If only one person runs cold, keep the whole family on one listing and adjust that person. In order of effort:
- Socks first. Cold feet keep many people awake, and the buffalo plaid socks that come with many sets are an easy first step.
- A plain long-sleeve tee under a short-sleeve top, in a color pulled from the print, keeps the look and adds a layer.
- A heavier blanket on that one bed, which changes nothing in the photo.
- A robe or coral fleece onesie for the morning only, taken off for the photo and put back on for present-opening.
The simplest option is one listing for everyone in the photo and a layer for the person who runs cold: a plain sweatshirt over a bamboo top, or socks and a robe on Christmas morning. One listing means one print, one color and one fabric, with each member's size chosen separately.
Shop the look
For a family that wants gingerbread across two fabrics, warm sleepers wear the navy satin set and cold sleepers wear the cream coral fleece onesie. Each is one listing where you choose each member and size.

Kids' Labels, Travel and Other Fabric Rules That Override Comfort
Three things can overrule what feels comfortable.
Children's sleepwear rules. In the US, children's sleepwear is regulated for flammability, and sets cut to fit tightly are excepted from the flame-resistance test, as are qualifying infant garments sized nine months or smaller. The CPSC's summary of the children's sleepwear rules sets out the coverage and exceptions. In practice that gives two routes, flame-resistant or snug-fitting, and we do not rank one as safer. Many PatPat fleece and polyester family listings state that their kids' and babies' pieces are flame-resistant. The kids' bamboo and modal sets are labeled snug-fitting, and a snug-fit set has to fit close: do not size up for a cozier, looser feel. Several cotton and bamboo family listings describe a close, snug cut without stating the route in the description, so read the label inside each child's piece when it arrives. Our guide to children's sleepwear rules explains the background. Adult sleepwear is not covered by these rules.
Size coverage. Fabric and size range travel together. If one person in the family needs 3XL or a 12-13Y, check that before choosing the fabric. Here is what was in stock on the family sets in this guide when we read them:
| Set | Fabric | Adults up to | Kids in stock | Baby in stock |
|---|---|---|---|---|
| Green gingerbread | Polyester fleece | 3XL | 2Y to 12-13Y | 3-6M to 12-18M |
| Red tree and Santa | Polyester fleece | 3XL | 2Y to 8-9Y | 3-6M to 12-18M |
| White and gray reindeer onesie | Coral fleece | 3XL | 2Y to 10-11Y | 3-6M to 12-18M |
| Green Christmas tree | Bamboo viscose | 3XL | 2T to 8 | 3-6M to 12-18M |
| Red gingerbread and tree | Bamboo viscose | 2XL | 2T to 10 | 3-6M to 12-18M |
| Blue Christmas tree | Cotton | 2XL | 2T to 10 | 3-6M to 12-18M |
| Navy gingerbread | Satin | 3XL | 2Y to 10-11Y | 6-9M and 12-18M only |
| Festive dog, short sleeve | Polyester knit | 3XL | 2Y to 10-11Y | None offered |
Stock changes daily, so treat this as a snapshot from the day we read it. The Christmas pajamas size finder filters by size across prints.
Travel to a different climate. A Florida family spending Christmas with relatives in Ohio, or a Minnesota family heading to Arizona, is packing for someone else's thermostat. Pack the lighter set and a warm layer, not the heaviest set: a fleece hoodie or socks can be added, but a too-warm onesie cannot be made cooler. Our holiday travel packing list covers the rest of the bag.
For a wider comparison of fabrics across every print, the Christmas pajamas fabric guide lists each fabric type side by side.
Frequently asked questions
Are bamboo Christmas pajamas cooler than fleece? On paper they are lighter and their listings call them breathable, while fleece listings describe warmth. We have not measured either, so treat bamboo viscose as the lighter choice rather than a cooling one.
What Christmas pajamas should I buy if I live in Florida? Start with bamboo viscose, cotton or a regular knit, and add a short-sleeve top for anyone who runs warm. Save fleece for a trip north.
Is fleece too hot for a heated house? It can be for warm sleepers, especially under a heavy comforter. Try lighter bedding first, then switch that one person to a regular knit.
Does PatPat sell flannel Christmas pajamas? No. The warm options are polyester fleece and coral fleece.
Are PatPat's bamboo pajamas pure bamboo? No. The family sets list 93% viscose from bamboo with spandex, and bamboo viscose is a type of rayon.
Can our family wear different fabrics and still match? Yes, if you keep the same color family and split fabrics by who runs hot or cold. One listing plus an extra layer for the cold sleeper is the simplest way.
Should I size up kids' pajamas to make them warmer? No for snug-fitting sets, which must fit close. For warmth, choose a warmer fabric in the child's true size.
Take the bedroom reading this week, pick the fabric, then check every family member's size on that listing, because sizes sell out one at a time and the fabric you want may not have the size you need by mid-December.
