Sleeveless vs. Sleeved Undershirt – Which Should You Choose?

Short answer: Sleeveless is coolest and adds the least bulk, while sleeves let the fabric absorb sweat under the arms before it reaches the shirt. Choose sleeves when the issue is sweat marks and warm rooms, and skip them when the issue is a smooth layer under a close fitting blouse.

Two different jobs

A vest can either keep the upper body dry and smooth, or it can cover the armpit. Sleeveless solves the first, sleeves solve both. Which one is right therefore does not come down to taste but to which problem you want to get rid of.

Without sleeves

The sleeveless model is coolest, adds the least bulk under a close fitting shirt and does not show in an open collar or under a short sleeved outer layer. For an ordinary day in a temperate room it is enough, and it is the one most people end up wearing most.

With sleeves

With sleeves the fabric reaches past the armhole and absorbs sweat before it can show in the shirt. It is the only model that does anything about sweat marks. For warm rooms, long days of meetings and parties, it is the one to pack. Have a look at bamboo vests for men.

What shows at the neck

A round neck shows in an open shirt. If you want to avoid it, choose a deep V neck or a model with a low round neck, and check it in the mirror with the shirt you wear most. That detail sends more vests back into the drawer than any other.

In winter

As a base layer under a jumper, sleeves are an advantage, because otherwise the arms have wool directly against the skin. If you want long sleeves, a bamboo long sleeved t-shirt for men works the same way and can be worn alone indoors.

In summer

When it is genuinely hot, a thin bamboo t-shirt is often better than a vest under a shirt, because it can be worn on its own. Have a look at the bamboo t-shirts for men, and save the sleeveless models for days when a shirt goes over the top anyway.

The same choice for women

For women the dividing line runs between a wide strap, a narrow strap and sleeves, and the same two jobs decide. Have a look at bamboo vests for women, where all three exist, and choose according to what goes over the top.

How many of each

Most people end up with a majority of sleeveless ones for everyday wear and two or three with sleeves for warm days and occasions. Do not buy only one kind before you have worn both for a whole day, because it is the hours and not the fitting room that reveal the difference. See also the undershirt as a base layer in winter.
