Bamboo undershirts and how to wear them

Short answer: You wear a bamboo undershirt as the layer closest to the skin, under a sweater or top. It should sit smooth without squeezing or folding. Here is a plain guide to fit, length, layers and care.

What an undershirt does

An undershirt is the layer that lies closest to the upper body. It protects your outer clothes from rubbing and gives a smooth layer under thicker fabric. Many wear it on cold days, but it can also be pleasant in the in between months if it is light and soft.

The right fit

An undershirt should sit close enough not to fold, but without squeezing the upper arms and chest. If it is too large, it rolls up under your clothes, and if it is too small, it rides up and can rub. Measure your chest and compare with the size guide.

Length matters

Choose a length that still covers when you bend or reach up. An undershirt that creeps up quickly becomes annoying. Often a slightly longer model is the most comfortable, so that it stays tucked into your trousers. Check the length on the product page before you buy.

Bamboo in clothing and the feel on the skin

Bamboo in clothing is viscose made from bamboo, and the fabric often falls soft and smooth. That can be pleasant under a knit, especially if you dislike scratchy fabric. See the range under bamboo underwear for men, and check for yourself.

Short or long sleeves

For cold days a layer with long sleeves can give more calm, and you can see the options among the long sleeve models. On warmer days a short sleeve is often enough. Choose by what you wear on top and how long you will be outside.

Layer on layer

Under several layers the undershirt should be thin and smooth so that it does not form bulges. Thick seams can show through clothing, so look for flat seams. Think in a few thin layers, so that you can take them off and on when the temperature changes through the day.

What you wear below

The whole day hangs together, and the undershirt is only one layer. Socks such as bamboo socks and underwear of the same kind often feel alike against the skin. That makes a day where nothing rubs or squeezes and you can think about something other than your clothes.

Washing and care

Wash by the care tag, preferably at a low temperature, and skip fabric softener, which can leave a film on the fibres. Let the undershirt air dry, and it keeps its shape for longer, and the neck does not stretch out so quickly. Change it every day, especially if you sweat.

Frequently asked questions

Should an undershirt sit tight or loose?

It should sit smooth and close enough not to fold, but without squeezing the chest and upper arms. Measure yourself and choose by the size guide.

How do I stop my undershirt riding up?

Choose a slightly longer model in the right size. If it is too small, it pulls up when you bend. Check the length on the product page before you buy.

Do I need an undershirt with short or long sleeves?

It depends on the weather and what you wear on top. Long sleeves give calm on cold days, while a short sleeve is often enough when it is warmer.
