White Briefs With a Fly – Guide

Short answer: White underwear with a fly is the classic under pale clothing. White does not show through light trousers, and the fly makes the model practical day to day. In bamboo viscose you get the classic in a softer and more breathable version than the cotton most people know it from.

When underwear should be white

Under white, beige or pale grey trousers and shorts, black underwear shows through clearly, while white and skin toned pairs disappear. That is the one real reason to keep white pairs in the drawer, and in summer and with pale workwear it is reason enough. See the range under bamboo underwear for men.

White or skin toned under white

If the trousers are thin and fully white, a skin toned pair is actually less visible than a white one, because white fabric under white fabric can read as a lighter rectangle. Under pale grey and beige, white is the right call. Under very thin linen trousers, expect something to show whatever you choose.

The fly makes the classic practical

The fly is a classic detail on traditional men's models, and many prefer it for purely practical reasons. It saves time, especially in workwear and outerwear where there are several layers to get through. Not every model has one, so check the individual description. JBS carries the classic models with more than a hundred years behind them.

How the pair should sit

A white model gives away a poor fit faster than a black one, because pale fabric highlights folds and pulls. The waistband has to lie flat without rolling, the legs have to finish without binding, and the rise has to be right so the fabric does not pull askew. When it all sits, a white pair looks better than anything else in the drawer.

Bamboo viscose suits white well

Bamboo viscose moves moisture away from the skin and out into the fabric where it evaporates, and that means fewer of the damp marks that are most visible on white. The material also releases dirt readily in the wash. Together that is why white bamboo underwear stays presentable longer than white cotton pairs do.

How to keep them white

Wash the white pairs on their own or with other pale items at 40 degrees. Avoid fabric softener, which gives a yellowish cast over time and also closes off the moisture transport. Wash them a little more often rather than leaving them in the basket, because old marks set and become hard to lift out later.

When they turn yellowish anyway

A pair that has taken on a yellowish cast can often be saved by soaking it overnight in cold water with ordinary detergent, followed by a normal wash. Chlorine based products work in the short term, but they break down the fibres and the elastic, and then the rescue costs more than the pair is worth.

How many white pairs do you need

Most people need far fewer white pairs than black ones. Two to four cover the days when the clothing is pale, and the rest of the drawer can be black. That way you do not wear the white ones out within six months, and they stay presentable for the days they are actually needed. See also the right fit in underwear and washing guide.
