Bamboo Basics undershirts for men and women
Short answer: The undershirts from Bamboo Basics are thin base layers that absorb sweat before it reaches the shirt. They come with and without sleeves and are worn all year round, both under shirts and under knitwear.
What the undershirt does
A thin layer between skin and shirt absorbs moisture and protects the outer layer. That extends the time between washes and makes the shirt more comfortable to wear all day. See the models in bamboo undershirts for men.
With or without sleeves
Without sleeves adds the least bulk under the arm, but does not catch sweat there. With sleeves protects the shirt best, because the fabric sits between armpit and shirt. See the difference in undershirt without sleeves or with sleeves.
Under the shirt at work
Under a light shirt, a skin tone or light grey undershirt is the least visible, because it creates no contrast through the fabric. A white undershirt can show as a clear edge. Choose a neckline that sits lower than the open collar.
For women
For women, the undershirt is worn both as a layer under knitwear and on its own in summer. A thin sleeveless model fits under a blazer, while one with short sleeves works under a thin jumper. Find the models in bamboo undershirts for women and at Bamboo Basics.
Why bamboo viscose
Bamboo viscose is smooth and soft and feels cool against the skin. It absorbs moisture and moves it away, so you do not feel clammy when you go from the cold outside to the warmth indoors. The fabric is thin enough not to add bulk.
Layering in winter
In winter, a thin layer under your knitwear does more than an extra jumper on top, because the air between layers holds the warmth. The bamboo viscose undershirt adds almost no bulk. See the whole principle in bamboo undershirt as a base layer.
Fit
An undershirt should fit closely enough not to crease under the shirt, but not so tightly that it rides up when you lift your arms. It should be long enough to stay tucked in all day.
Washing and replacing
Undershirts are washed after every wear and must therefore handle many washes. 40 degrees and air drying keep the shape longest. Avoid fabric softener, which makes the fabric less absorbent. See the washing guide.
How many you need
If you wear an undershirt every working day, you need at least five, ideally a couple more, so you do not have to wash midweek. Identical models are easy to replace together when they wear out.
When to replace them
A neckline that has gone slack and fabric that has thinned under the arms are signs that the undershirt is finished. When it starts to show through the shirt, it is time for a new one.
Frequently asked questions
Should the undershirt have sleeves or not?
With sleeves protects the shirt best from underarm sweat. Without sleeves adds the least bulk and is a good choice in summer or if you do not sweat much.
Which colour shows least under a white shirt?
A skin tone or light grey shows least, because it creates no contrast through the fabric. A white undershirt is often more visible through a thin shirt.
Can the undershirt be worn on its own?
Yes, especially in summer or at home. The models are simple enough to work alone, but they are mainly meant as a thin layer under other clothing.
