In my experience, bamboo pajamas don’t smell bad, even after a sweaty night, and they feel really comfortable. If you wake up damp from night sweats, that combination matters. I wanted to find out why they work for me, what the evidence says, and what to look for if you want to try a set.
Quick answer: pajamas sold as “bamboo” are usually viscose (rayon) made from bamboo pulp. They tend to smell less than polyester because viscose is a plant-based cellulose fiber, like cotton, and not because bamboo is antibacterial. They’re soft, light and absorb moisture, which helps on sweaty nights. The catch is that they can feel damp once soaked, so having a second set to swap into helps.
Quick answers
Do bamboo pajamas smell?
Less than synthetic pajamas, in general. A 2024 study from the University of Alberta and the University of Otago found cotton and viscose absorbed and released fewer odor compounds from sweat than polyester, nylon or wool. They can still smell if you wear them for days without washing.
Are bamboo pajamas good for night sweats?
Many people find them comfortable for night sweats because the fabric is soft, light and absorbent. They are not a treatment, and a heavily soaked set can feel damp and clingy, so keep a spare.
Is bamboo fabric naturally antibacterial?
Not as far as the evidence shows. The US Federal Trade Commission says there is no evidence that rayon made from processed bamboo is naturally antibacterial.
What should I check on the label?
The fiber content. Look for mostly viscose (or rayon) made from bamboo, ideally with little or no polyester.
Why bamboo pajamas smell less
The reason is the type of fiber, not the plant it came from. In the 2024 study, researchers soaked cotton, viscose, polyester, nylon and wool in simulated sweat and measured the odor compounds each released. Cotton and viscose absorbed and released smaller amounts than the other fibers. Polyester is the odds-on offender: it is oil-loving, so it absorbs more of the oily compounds in sweat, which can later break down into smelly substances. You can read the University of Alberta write-up of the study.
Bamboo pajamas are usually viscose, so they fall on the cellulose side of that divide, along with cotton. That fits what I’ve found: a bamboo set smells fresher than a polyester one after the same night.
What bamboo marketing gets wrong
You will often see “naturally antibacterial” on bamboo clothing. The FTC says that when bamboo is turned into rayon or viscose, it is no longer the plant, and that there is no evidence the fabric is naturally antibacterial. Companies that make those claims need reliable scientific evidence. See the FTC guidance on bamboo fabrics. So I would not buy pajamas because of that claim. Buy them because viscose is soft and, as the study suggests, holds less of the sweat odor that polyester does.
Why they feel good on sweaty nights
- Soft and light. Viscose has a smooth drape, so there is little to scratch or cling when you toss and turn.
- Absorbs moisture. Like cotton, it takes up sweat instead of leaving it sitting on your skin, as polyester can.
- Relaxed fits breathe. Short sleeves, shorts and loose cuts let air move around you. Buying guides for hot sleepers consistently recommend relaxed fits and avoiding polyester-heavy blends.
The limits
Viscose absorbs a lot, and a set that is truly soaked can hold the moisture and cling to you until it dries. Some brand guides also point out that very thin fabric, around 150 gsm or less, can cling more once it is wet. If you sweat heavily, keep two or three sets so you can change in the night.

What to look for when you buy
- Fiber content: mostly viscose from bamboo. A little spandex (about 5%) gives stretch. A big share of polyester works against the point.
- Fit: relaxed, with short sleeves and shorts if you run hot.
- Care label: most are machine washable on a cold, gentle cycle. Check it before you buy.
- Honest labeling: in the US it should say viscose or rayon from bamboo, not just “bamboo”.
- Quantity: a multi-pack or two sets lets you rotate, which matters more than any single feature.
Bamboo pajamas I would look at
I checked each of these on Amazon on October 29, 2026. Prices and stock change, so check the current listing. All have add-to-cart available and the fabric content below comes from the listing.
Women
- Latuza women’s V-neck short-sleeve pajama set (shorts): 95% viscose made from bamboo, 5% spandex. About $20 when I checked, rated 4.6 stars from more than 10,000 ratings. Machine wash cold on gentle, do not tumble dry.
- Latuza women’s short-sleeve top with pants: the same fabric with full-length pants. About $35, rated 4.6 stars from more than 5,000 ratings.
Men
- Latuza men’s V-neck viscose sleep shirt, 3-pack: 95% viscose made from bamboo, 5% spandex. About $45 for three (roughly $15 each), rated 4.7 stars from 146 ratings. These are tops only, so pair them with your own shorts. Three shirts make rotating easy.
- BAMBOO COOL men’s pajama set: a full set, but the fabric is 74.5% viscose from bamboo and 25.5% polyester. About $50, rated 4.5 stars from 337 ratings. That polyester share means it may hold more odor than the pure viscose options above, so I would pick it only if you want a sturdier set.
I haven’t tested all of these sets myself, so I’m describing them from their listings and ratings, not from my own use.
How to keep them fresh
- Wash them regularly. Odor comes from sweat and the bacteria on your skin, and no fabric prevents that completely.
- Follow the care label. The Latuza listings say to machine wash cold on a gentle cycle, not to use bleach, and not to tumble dry.
- Air them out in the morning and rotate between two or three sets.
- If the sweating is new, or comes with fever, weight loss, chest pain or dizziness, see a doctor.
The bottom line
Bamboo pajamas are a comfortable, practical choice for night sweats, and they smell less than polyester. The reason is that viscose is a cellulose fiber, not that bamboo is antibacterial. Pick a set that is mostly viscose, keep a spare, and wash them regularly.
