Size guide for Bamboo Basics men

Short answer: Bamboo Basics uses standard men's sizes from S to XXL. Because much of the range is sold in multipacks, it is a good idea to try one piece first and then buy the pack.

Find the chart

The measurements are in the Bamboo Basics men's size guide. Use it before buying a whole pack. Charts differ between brands, so a size that fits at one brand may be too big or too small here. Go by centimetres rather than letters.

Try before buying the pack

If you buy a multipack in the wrong size, you end up with several pieces you will not wear. Buy one first if you do not know the model, and wear it for a few days. If it fits, you can buy the pack with confidence. More in underpants in multipacks.

How to measure

For underpants, measure your waist where your trousers usually sit. For tops, measure your chest at the widest point with your arms down. Use a soft tape, keep it level and do not pull it tight. Write the numbers down for your next purchase.

Underpants

Choose by the waist measurement where your trousers sit, not by your trouser size. The waistband should sit firmly without digging in, and the legs should not ride up when you walk. See the models in bamboo underpants for men and compare with the chart.

Tops

T-shirts and undershirts must fit at the shoulder first. If the shoulder seam sits outside the shoulder, the top is too big. The length should reach past the belt so it stays tucked in. For wear under a shirt, choose the closer fit. See bamboo t-shirts for men.

Socks

Socks follow shoe size in ranges, usually two to three sizes per sock size. If you are at the top of a range, the next size up may be more comfortable, so the heel does not slip under your foot. See sock sizes.

Between two sizes

If you are between two, think about the use. Underpants and undershirts for under a shirt fit best in the smaller size, as the fabric gives a little. A t-shirt worn alone and loose can be taken in the larger one.

After washing

At 40 degrees with air drying, the clothes keep their size. A tumble dryer can tighten the fabric slightly over time and wear the waistband elastic. Skip fabric softener too, as it makes the fabric less absorbent. See the washing guide.

Why measurements beat habit

A measurement in centimetres is the same at every brand, while letter sizes are not standardised. Measure yourself once, write the numbers down and use them every time you buy. That way you get it right even with brands and models you have not tried.

The fabric gives a little

Bamboo viscose stretches slightly with wear. New underpants may feel a little snug for the first hour and then fit right for the rest of the day. If they are loose from the start, they are probably too big, and the smaller size is better.
