An Overview On Long Underwear

Long underwear comes in three different weights: lightweight, for moderate to cool weather; midweight for cold temperatures; and heavyweight for below-freezing temperatures. The main goal of this base layer is to manage moisture, but the heavier-weight versions will also add more warmth.

These tops and bottoms can be worn alone or under clothing. Most are made with moisture-wicking fabrics to keep you dry and cozy. Though they can be made from sustainable fabrics like merino wool or silk, the most popular fabric is polyester, usually with some Spandex or Lycra added for stretch. Synthetic fabrics are so widespread because they’re good at dissipating sweat and are less expensive than merino wool.

Some long underwear also has a finish to slow the growth of odor-causing bacteria, a great feature to have for those who sweat more.

Finally, long underwear should fit snugly, but not too tightly. When loose, the moisture-wicking features will not be as effective.

The Long Underwear Buying Guide

  • Natural materials like wool and silk may be warm, but they are not as durable as polyester — good to know if you expect to wear and wash them often. However, if you’re planning a multi-day trip, keep in mind that even the best anti-stink coating won’t prevent synthetic long underwear from turning smelly after a few days.
  • Merino wool is tough to beat when it comes to avoiding stink. It has natural antibacterial properties — no extra fabric treatment needed — that keep it stink-free even after multiple wears without washing.
  • Always read the washing instructions before laundering your long underwear. Most can be machine washed and will last longer if they’re air dried.
  • For activities that increase body temperature, such as running and hiking, light or midweight long underwear is a good choice. Heavier-weight base layers are ideal for less aerobic activities, like fishing.
