The first thing everyone notices about Cool-jams BambooSoft is the feel. The second thing, a few months in, is that it still feels that way, but only if it has been washed right. Viscose from bamboo is a wonderfully soft fiber, and like most wonderful things, it has opinions about how it wants to be treated.
This is the BambooSoft owner's manual: the full care routine, the reasons behind each step, the short list of things to never do, and answers to the questions our inbox asks most. If you want the wider background on the fiber itself, we have a separate piece on what bamboo viscose actually is. This guide stays focused on your BambooSoft pieces and how to keep them at their best.
Why viscose from bamboo needs gentler care than cotton
Viscose from bamboo is a regenerated fiber with a smooth, delicate structure. That structure is what gives BambooSoft its drape and its cool, gentle hand. It is also why aggressive heat and harsh chemicals damage it faster than they damage sturdy cotton. The whole care philosophy fits in one sentence: keep it cool and keep it gentle. Everything below is just that idea applied to each step of laundry day.
Water temperature: cold, always
Wash BambooSoft in cold water, full stop. Hot water swells and stresses the fibers, which leads to shrinking and a rougher feel over time. Cold water cleans sleepwear perfectly well and preserves both the fit and the softness you bought it for. There is no scenario where hot water helps and several where it hurts, so this is the easiest habit to lock in first.
Detergent: mild and simple
Use a mild, gentle detergent. Avoid heavy-duty formulas and anything with added bleach or brighteners. You need less detergent than you think for sleepwear, and an overdose leaves residue that stiffens the fabric. When in doubt, use a little less than the cap suggests.
Machine washing: yes, on gentle
BambooSoft is machine washable on a gentle or delicate cycle. Two easy upgrades protect it further: turn pieces inside out to shield the surface you actually touch, and use a mesh laundry bag so zippers and hooks sharing the load cannot snag the fabric. Both take five seconds and pay off for years.
The dryer: skip it entirely
This is the rule that matters most. High heat is the fastest way to shrink viscose from bamboo and permanently roughen its smooth surface. Lay pieces flat or hang them to dry, away from direct sunlight. They dry surprisingly quickly, and air drying is the single biggest thing you can do to extend their life.
Hand washing: when and how
Hand washing is never required, but it is the gentlest option for pieces you especially love. Use cool water, a small amount of mild detergent, a gentle swish, and a thorough rinse. Press the water out by rolling the garment in a towel. Never wring or twist, because that stresses the fibers at their weakest point, which is when they are wet.
Storage: loose, not compressed
Fold BambooSoft loosely in a drawer or hang it. Avoid cramming it into a packed shelf for months, because compression sets creases into the drape. If you rotate sleepwear seasonally, store it clean, since body oils left in fabric are what quietly attract damage over time.
The never list
- No chlorine bleach. It attacks the fiber itself.
- No fabric softener. It coats the fibers and dulls the natural softness. BambooSoft does not need it.
- No high heat, in the washer, the dryer, or the iron. If you must iron, use the lowest setting with a pressing cloth.
Frequently Asked Questions
Can I put BambooSoft in the dryer?
No, and this is the one rule worth memorizing. High heat shrinks viscose from bamboo and permanently roughens its smooth surface, which is the exact thing you bought it for. Lay it flat or hang it to dry. It dries quickly on its own, we promise.
Does BambooSoft shrink?
Washed cold and air dried, shrinking is minimal. Nearly every shrinking story we hear ends with the words "and then I put it in the dryer." Keep heat out of the routine and the fit stays true.
What detergent should I use?
A mild, gentle detergent, and less of it than you think. Skip heavy-duty formulas and anything with built-in bleach or brighteners. Harsh chemistry is hard on delicate fibers, and detergent residue makes soft fabric feel stiff.
Can I use fabric softener?
Please do not. Fabric softener works by coating fibers with a waxy film. On BambooSoft, that film buries the natural softness under a layer of buildup. The fabric is already the soft one, so let it do its thing.
How do I remove stains?
Act fast and stay gentle. Use cold water and a small amount of mild soap, dabbed rather than scrubbed, as soon as you can. Avoid hot water, which can set stains, and never use chlorine bleach. For stubborn spots, repeat the gentle treatment rather than escalating to something harsh.
Does it really get softer over time?
It stays beautifully soft, and many customers say it feels even more broken-in and gentle after the first few washes, the way a favorite garment does. What we can tell you for certain is that washed correctly, the softness lasts. Washed hot and machine-dried, no fabric can save you.
Can I iron BambooSoft?
Usually you will not need to, because the drape releases most wrinkles once you hang it. If you want a crisp finish, iron on the lowest setting with a pressing cloth between the iron and the fabric. Never use high heat directly on the surface.
How often should I wash it?
After two to three wears, like any sleepwear. Overwashing ages every fabric, and underwashing leaves body oils in the fibers, which is its own slow damage. Two to three wears is the happy middle.
Help, I accidentally dried it. Is it ruined?
Take a breath. One accident, especially on low heat, is usually recoverable. Check the fit and the feel. If it tightened slightly, wearing it will relax it somewhat. What matters is that the dryer does not become a habit, because the damage from heat is cumulative.
How long will BambooSoft last?
With proper care, years of regular wear. Cold washing, air drying, and no softener are what protect both the fiber and the fit. The routine sounds fussy written down, but in practice it is one habit: wash it cold, hang it up, walk away.
Care for it well and it takes care of you
Cold wash, gentle cycle, air dry, no softener. That is the whole religion. Follow it and your BambooSoft sleepwear will stay the softest thing in the drawer for years.
