Underwear for Sport and Training – Men

Short answer: Underwear for sport has to keep you dry, stay in place without pinching, and not chafe during movement. Close fitting models with a long leg in bamboo viscose meet all three requirements, which makes them a strong choice for running, strength training and classes.

Dry skin matters most

Damp skin withstands friction far less well than dry skin, which is why chafing and blisters only appear once you have turned wet with sweat. Bamboo viscose moves the moisture away from the skin and out into the fabric where it evaporates. See the range under bamboo underwear for men.

The cut has to sit close

A loose model folds during movement, and a fold is exactly what chafes. For training the item has to sit close to the body all the way around, without pinching at the groin or the leg opening. If there is a red mark from the waistband afterwards, it is too tight, and then you need a size up or another model.

A long leg for most forms of training

For running, cycling and anything where the thighs work against each other, a long leg is the simplest answer to chafing. The opening has to end past the widest point of the thigh, otherwise it rolls up and lands in the middle of the area it was meant to protect. For strength training a shorter leg often works fine.

Wash the same day

An item worn for training has to be washed the same day and cannot be worn again. Odour develops in the damp period before the wash rather than during it, and an item that has lain rolled up in a bag for an evening has already started. That habit matters most for whether training clothes stay fresh.

Number of sets

If you train three times a week, add three sets to whatever you otherwise use for everyday wear. Using the same ones for both wears them out twice as fast, and the whole drawer has to be renewed at once. Keep training clothes separate, even when they are the same model.

The rest of the layer

The same logic applies to the upper body. An inner layer that soaks through and stays wet cools you as soon as you stop, and that is felt most outdoors in winter. See bamboo t-shirts for men and bamboo underwear for men, where the material is the same.

Bamboo against synthetics for sport

Synthetic fibres dry fastest and are strongest when wet, and for competition over long distances they still have an advantage. For everyday training, the gym and classes, bamboo is at least as good, softer against the skin and smells less afterwards, because the fibre does not bind skin oils in the same way.
