Undershirt with or without sleeves for men

Short answer: A bamboo undershirt for men can have sleeves or not, and the choice depends on where it will be used. Without sleeves it is discreet under a shirt or a short-sleeved top, while sleeves give a little more coverage and warmth. Here is a calm walk-through of which suits you.

What an undershirt is for

An undershirt is an innermost layer that sits between the skin and the outer clothes. You wear a bamboo undershirt for men to keep the outer clothes free of sweat and to have a soft surface closest to the body. It is not meant to be seen, but to make the day more comfortable.

Without sleeves

A sleeveless undershirt is discreet under clothes with short sleeves or none. It leaves the arms bare and gives more freedom in the shoulders. It suits warmer days or if you warm up quickly. If you look at bamboo underwear for men, it is the classic basic model.

With short sleeves

With short sleeves you get a little more coverage over the upper arms and a fit like a T-shirt. It is a good choice if you want an extra layer at the shoulders or wear an open outer layer. The sleeve must not stick out below the sleeve of the outer clothing.

With long sleeves

Long sleeves are a warmer, more covering layer for cold days when you also want to protect the arms. They fit under a sweater, but must not bunch at the elbow. They come as long sleeve models, which can also be worn alone in the in-between seasons.

Fit and length

The undershirt should sit close enough not to wrinkle under the outer clothes and be long enough to stay in the trousers. If it is too short it rides up, and if it is too tight it pulls. Choose your usual size and move around when you try it on.

Colour under clothes

White can show through under a light shirt, and black can be seen under white. Choose a colour that goes with what you wear over it, for example a skin-like or grey tone under light things. Test the colour in daylight in front of the mirror before you decide.

Combine with boxer briefs

If the undershirt fits, the rest of the base layer often does too. Bamboo boxer briefs in the same fabric give a consistent feel and a set that feels like one. Then you are dressed in one layer before you put on the rest.

Washing and care

Wash according to the care label and avoid high heat so the shape holds. Wash undershirts with similar colours and do not use fabric softener on bamboo viscose. Let them dry flat or on a hanger so they do not pull in length or wear early.
