Men's underpants sizing and the measurements that count
Short answer: Men's underpants sizing depends on your hip measurement, not on the size you usually wear in trousers. Measure yourself, compare with the size guide and take the larger size if you fall between two. Here are the measurements that count.
Start with a tape measure
The most reliable approach is to measure yourself. Take a soft tape measure and go around your hips at the widest point. Write the number down and hold it up against the size guide for the exact pair you are looking at. Never guess from your trousers, because their sizes follow other rules.
Hips and waist are not the same
Your waist measurement decides where the waistband sits, but your hips decide whether the underpants lie calmly. Many people choose by the waist and end up with a pair that is too small. Use the hips as the main measurement and check the waist afterwards. Browse bamboo underpants for men.
Leg length matters too
Leg length is the next measurement. With strong thighs a short leg can press, and with slim thighs a long leg can wrinkle. Measure around the thickest part of your thigh and choose a length that ends in roughly the same place every time you walk.
When you fall between two sizes
If you fall between two sizes, take the larger one for a loose feel and the smaller one for a close fit. Think about how you use them. For desk work a little extra room is pleasant, while for sport you may want them close to the body.
Fabric with stretch and without
Some fabrics give a little and others do not. Bamboo clothing is viscose made from bamboo, and many models have elastane mixed in so they follow the body. Read the material in the description so you know whether to go by the measurements or allow some extra room.
Washing and shrinking
The size can change in the wash if you use high heat and a tumble dryer. Follow the care label and let them air dry if you can. That way you keep the fit you measured for. If you are unsure, lay a pair flat and measure it again.
How to test the fit at home
Put them on, walk, sit and bend forward. Notice whether the waistband cuts in or the leg creeps up. If something presses, the size is too small, and if something hangs, it is too big. Give them a few calm days before you decide to buy more.
Write down your measurement for next time
Write your hip measurement and the size you ended up with in a note on your phone. Then you avoid measuring again the next time you buy. If the size fits, you can use it for the rest of your bamboo underwear for men and for bamboo T-shirts for men.
