Resteröds long underpants for winter

Short answer: Long underpants in bamboo viscose are worn as a base layer under trousers in winter. They add warmth without bulk and do not itch the way wool can, and they fit under work trousers, jeans and suit trousers alike.

A base layer rather than extra trousers

A thin inner layer holds warmth better than a thicker outer pair on its own. The air between layers insulates, and you can move freely. That is why long underpants are used for outdoor work and cold days when you stand still for a long time. See the styles in Resteröds.

Bamboo rather than wool

Wool is warm but itches for many, especially on the thighs and behind the knee. Bamboo viscose is smooth on the skin and moves moisture away, so you do not feel clammy when you go indoors. On the other hand, wool insulates more in hard cold. The comparison is in bamboo vs wool.

Length and fit

The leg should end at the ankle without riding up when you move. The waistband should hold without digging in, even when you sit. If you are between two sizes, choose by waist, as leg length is rarely the issue. See the size guide.

Who they are for

They are mostly worn by people who work outside, cycle long distances or get cold legs indoors. Many also take them on winter holidays or wear them under rain gear. If you are unsure, try one pair first on a cold day. See the whole group in bamboo long johns.

When you notice the difference

The difference between a base layer and nothing is greatest when you stand still in the cold, for example on a platform or at a football match. When you walk fast, the body makes its own heat, and moving moisture matters more than extra insulation. Here bamboo viscose helps by carrying sweat away.

With the rest of your winter wardrobe

Long underpants work best with an undershirt in the same material, so your whole body has a thin inner layer. On top you can add knitwear and a jacket to suit the weather. More advice on layering is in bamboo clothing for cold days.

Washing

40 degrees without fabric softener. Avoid the tumble dryer, which wears the waistband elastic and can shrink the fabric slightly. Hang them by the waistband so the legs hang straight and dry quickly. Wash them after a few days of wear. See the washing guide.

How many pairs you need

If you only wear them on the coldest days, two pairs are enough. If you work outside all winter, three to four pairs are better, so a dry pair is always ready. A pair that rests between wears also keeps its waistband shape for longer.
