What do you wear under sweatpants

Short answer: Ordinary underwear. Sweatpants are not cut to be worn directly against the skin, and a layer of underwear keeps sweat away from the thick fabric, so the trousers need washing less often.

Sweatpants are not made to touch the skin

Sweatpants are cut like outerwear. They are made of thick fabric, with seams and a waistband that are not meant to sit against the skin all day. The answer is therefore simple: wear underwear. It makes the trousers more comfortable and keeps them fresh between washes, because you wash the inner layer instead of the thick trousers.

Underwear keeps sweat away

The inner layer is washed every day, and sweatpants are not. A layer of underwear takes up sweat and skin oil, so the thick fabric of the trousers does not have to. That means sweatpants can be worn several times between washes. See women's bamboo sweatpants for the days at home.

Without a layer they need washing every time

Directly against the skin, sweatpants become an inner layer. They then pick up sweat and skin oil and need washing after every wear, just like underwear. That is not wrong if you want it that way, but it means more washing of a thick garment, and it rarely makes life more practical.

Seams are felt less with a layer

A smooth inner layer takes away the friction from thick seams. The seam does not touch the skin directly, and the pressure is spread over a larger area. That makes a difference when you sit for a long time. See bamboo panties as a layer under sweatpants if you want something soft and smooth against the skin.

Choose thin, smooth underwear

Thin, smooth underwear does the most good under thick sweatpants. It does not bunch up and lies flat under the trousers. Avoid underwear with thick seams or heavy embroidery, or you only move the problem from the trousers to the underwear. Choose something whose fit you can forget. That is the whole idea of an inner layer.

How to look after your sweatpants

With an inner layer, sweatpants can hang on a hanger or over a chair between wears. In a pile they get no air. Wash them when they have stains or smell, not by the calendar. That keeps the amount of laundry down without compromising on everyday comfort. The rule is easy to follow and needs no special routine.

Sweatpants at home and outdoors

At home people often sit in sweatpants all day, and outdoors they are worn for short walks. The same rule applies in both cases: a layer of underwear under the trousers. That gives the same comfort whether you sit on the sofa or go for a walk. See women's most popular items for the models people choose most.

Underwear for every day

Underwear under sweatpants does not have to be special. It should be clean, smooth and in your size. Change it every day as usual, and let the sweatpants go several times between washes. That gives you the comfortable fabric on the outside and a layer that takes up sweat and skin oil where you need it.
