Frequently asked questions
Check out the BOXR FAQ for answers to all your questions about our comfortable basics.
What are the benefits of a Bamboo Undershirt?
You stay dry under your shirt, it feels silky soft on the skin, and it stays invisible without riding up. Exactly what you should expect from an undershirt, and nothing you need to think about after that.
How do I keep an Undershirt from showing under a dress shirt?
Go for a slim fit model with a V-neck in a light colour. Bamboo undershirts are thin enough not to show through and long enough not to ride up.
Are Bamboo Undershirts suitable for men who sweat a lot?
Yes. Bamboo absorbs up to 70 percent more moisture than cotton and dries faster, making it ideal for warm days or intensive workdays.
What kind of Undershirt suits me best?
That depends on what you're wearing it under. A close-fitting undershirt sits neatly beneath a dress shirt, while a regular fit gives you more freedom of movement. Every model stays put thanks to the extra length.
How long does a Bamboo Undershirt last?
With proper care your undershirt keeps its shape. Should a hole appear within six months, the BOXR No Holes Guarantee gets you a free replacement.
Is a Bamboo Undershirt better than cotton?
For an undershirt, yes. Cotton soaks up sweat and holds onto it, so you spend the rest of the day with a damp layer against your skin. Bamboo wicks it away and dries faster. And because bamboo feels softer, you stop noticing the layer that sits against you all day.
How do I wash an Undershirt?
Machine wash at 30°C with similar colours. No chlorine or bleach, and fabric softener isn't needed. Don't tumble dry: laying it flat to dry keeps the fabric and the fit in the best shape.

What makes a bamboo undershirt so special?
Bamboo fibres have a structure that wicks moisture away quickly and helps regulate heat. That keeps the fabric comfortable, even when you wear the undershirt for a long time. Compared to cotton, bamboo feels soft and light. That makes a BOXR undershirt a comfortable base under your everyday clothes.
A fit that moves with you
A good undershirt shouldn't shift or pinch. That's why BOXR bamboo undershirts are extra long, so they stay neatly tucked into your trousers. The mix of bamboo and elastane gives stretch that moves with your body while keeping its shape. So the shirt feels comfortable and airy while you wear it.
When do you wear a bamboo undershirt?
You can wear a bamboo undershirt all year round. The thin fabric makes it suitable as a base layer under all kinds of clothing. Which undershirt feels right depends on things like the season, what you wear over it and how much you sweat during the day.
A bamboo undershirt in summer
On warm days, a bamboo undershirt helps wick moisture away from your skin. That means sweat is less likely to go straight into your shirt or T-shirt. The light, breathable fabric makes an undershirt a good extra layer without wearing a heavy shirt under your clothes. Prefer a shirt you can also wear on its own? Then take a look at our men's bamboo T-shirts.
An extra layer in winter
In winter, an undershirt can work as an extra layer between your skin and your outer clothing. So you don't have to go straight for a thick base layer. Want more coverage on your arms? Then take a look at our long-sleeved undershirts.
Under a shirt at the office
An undershirt under your shirt forms an extra layer between your skin and the fabric of your shirt. That's pleasant during a long workday and helps stop sweat from soaking straight into your shirt. The extra length helps the undershirt stay tucked in when you move or get up regularly.
For sweat patches
Do you quickly get visible sweat patches? A bamboo undershirt can help absorb moisture and wick it away from your skin before it reaches your top layer. An undershirt won't stop you sweating, but it does add an extra layer between your skin and, say, your shirt.
For sensitive skin
An undershirt sits directly against your skin all day. A soft fabric can therefore be pleasant if your skin reacts quickly to clothing. Bamboo feels smooth and soft, forming a comfortable layer between your skin and your shirt, jumper or T-shirt.
Bamboo or cotton: which suits you better?
Bamboo and cotton can both be used for an undershirt, but they feel different to wear. Bamboo feels soft and light and wicks moisture away. That can be pleasant if you sweat easily, want a soft fabric against your skin or wear an undershirt under other clothes throughout a long day.
Cotton often feels a bit sturdier and is a familiar choice for a lot of men. Mainly looking for a soft, breathable base layer that helps wick away moisture? Then a bamboo undershirt may suit you better. In the end, it's mostly your preference and when you wear the undershirt that decide which material feels right.
Fresh, day after day
The moisture-regulating properties of bamboo make our undershirts well suited to men who are on the move or active a lot. The fabric helps wick moisture away from the skin, so the undershirt stays comfortable during a long day too.
Keeping your undershirts in top shape
With the right care, your undershirts stay looking good for longer. Wash your bamboo undershirt at a maximum of 40 degrees, let it air dry and avoid fabric softener. That helps the shirt keep its elasticity, softness and fit.

Comfort you notice without feeling it
A good undershirt works without drawing attention. BOXR makes basics that fit comfortably, without itchy seams or chafing fabric. We take care of the basics, so you can focus on the rest of your day.
Isn't wearing an undershirt warm?
An undershirt doesn't automatically feel warmer. A thin bamboo undershirt is breathable and helps wick moisture away from your skin. That can make it pleasant to wear a light base layer under your shirt or T-shirt. On warm days, the undershirt also helps stop sweat soaking straight into your outer clothing. In winter, that same extra layer works in your favour when you want to hold on to a bit more warmth.
