Bamboo undershirt for men and choosing the right size

Short answer: A bamboo undershirt for men should fit close enough to lie smooth under other clothes, but not so tight that it pulls across the chest. Measure chest and waist and compare with the size guide. Here is what to check before you choose.

What an undershirt is for

An undershirt is a thin inner layer between the skin and the rest of your clothes. It keeps the outer layer clear of sweat and gives a little extra warmth in winter. Bamboo viscose is soft on the skin, which makes it a comfortable choice for the purpose.

Measure chest and waist first

Take a tape measure and measure around the chest at its widest point and around the waist. Compare with the size guide for the specific model, since sizes vary. If you are between two sizes, decide whether you want a close or a slightly looser fit.

Sleeveless or with sleeves

Sleeveless models allow free movement and stay hidden under a close fitting sweater. Models with short or long sleeves give more warmth and cover the arms. Look at long sleeve models if you often feel cold around the arms in the cold season.

Length on the body

The undershirt must be long enough to stay tucked in when you bend or reach up. If it is too short, it rides up and forms an edge. Check the length in centimetres in the size guide and choose a longer model if you are tall.

Neckline under other clothes

Choose a neckline that cannot be seen under a shirt or sweater. A round neck suits most people, but a deep neckline is better under open collars. Check that the neck does not pull when you raise your arms.

Seams and comfort

Flat seams and soft fabric mean the undershirt does not chafe, even if you wear it all day. Notice whether anything presses over the shoulders or under the arms. It is often small things that make the difference between a garment you wear and one you avoid.

Washing and care

Follow the care label, wash on a gentle cycle and avoid fabric softener. Hang the undershirt on a line so it keeps its shape. Viscose can shrink if washed too hot, so keep that in mind when choosing the size.

Combine with the rest of the underwear

Once the undershirt fits, you can put the whole layer together. Bamboo underwear for men and bamboo boxer briefs in the same softness give a uniform feel. Start with two or three pieces so you can change without washing every day.

Frequently asked questions

Should an undershirt fit tightly?

It should lie smooth without pulling. A close fit bulks less under other clothes, but it must not squeeze across the chest, arms or neck.

How do I choose a size if I am between two?

Choose the larger for a loose fit and the smaller for a close fit. Also check the length in the size guide.

Can a bamboo undershirt shrink?

Viscose can shrink if it is washed too hot or dried hard. Follow the care label and choose a gentle cycle and air drying.
