Boxers, trunks and briefs for men
Short answer: Boxers, trunks and briefs are the three most common cuts in men's underpants, and they differ in leg length, fit and how much support they give. Which cut is best depends on your trousers, your activity and your own taste. Here is a sober overview.
Boxers
A boxer is loose and has a longer leg, usually without pulling. Many like it because it gives freedom and air and suits relaxed days. Under close-fitting trousers, though, the fabric can bunch and the leg can ride up, so the fit should be tried.
Trunks
A trunk is something in between, with a shorter leg that sits closer to the body than a boxer. It gives more support and lies flat under trousers, and it often keeps its position when you move. See bamboo underpants for men to compare the different cuts.
Briefs
A brief is the shortest and most close-fitting, without legs, and it gives the most support. It lies flat under tight trousers and is practical for sport. Some find it too tight, so try it and choose a size that does not pull at the groin or the waistband.
Which cut for which trousers
With loose trousers and shorts a boxer suits well, while trunks and briefs are better under tight trousers, where you do not want the underwear to make folds. For a suit many choose a trunk. Think about whether the underwear should be invisible or whether you put comfort first.
For daily life and for sport
In daily life you can choose by comfort, but for sport support and fit matter more. A cut with some leg length can prevent chafing between the thighs, and one with a firm waistband stays in place. Try different cuts and find out what works for you.
Waistband and seams
The waistband should sit firmly without cutting in, and the seams must not chafe. Look at how the waistband is made and whether it is wide enough to lie flat. Seams on the inside can be an advantage if you chafe easily.
Size and fit
Choose the size that suits your waist and body, and follow the size chart. Underwear that is too tight can chafe, and underwear that is too loose can bunch. Take your measurements and compare them with the chart instead of guessing from what you usually wear.
What else you wear
Underwear is part of the whole. See bamboo underwear for men if you want to see more than underpants, and bamboo T-shirts for men for what goes over them.
