Keeping warm with thermal underwear

Plus size thermal undergarments provide long-lasting warmth and are the sensible way to stay warm and cozy no matter what the temperature. Whether you are at work or play, thermal undergarments are a cool-weather essential. After all, nothing is warmer under plus size ski clothes than long underwear.

About Long Underwear

Plus size thermal undergarments go by many other names, like long johns, long underwear, and thermals. However, no matter what their name, everyone agrees that these garments are the most comfortable way to add warmth when temperatures drop. Individuals with poor circulation or circulatory diseases find them to be a superior way to keep their extremities warm.

Thermals are two-piece sets of a matched long-sleeve top and a bottom with long legs designed to provide an extra layer of warmth underneath other clothing or when worn alone. Typically, these garments are made from textiles with a waffle-like appearance, which gives them their signature look and feel.

However, intimate apparel, like most fashion garments, is constantly evolving and today's thermal intimates are as good-looking as they are warm. Blends of 97 percent modal and 3 percent Lycra® spandex, cotton and nylon blends, and silks all wick perspiration from the body to help retain body heat, while adding a luxurious look and feel to the garments.

Styles of Plus Size Thermal Undergarments

Long underwear is a winter must-have for lounging around the house or whenever you feel chilly. Wear them for extra warmth when enjoying activities like cross-country skiing, hunting, backpacking, or ice-skating. They are ideal under sweaters or jeans and can double as pajamas on the coldest nights. Look for styles like these when shopping:

  • Crew necks
  • Scoop necks
  • V-necks
  • Sleeveless, short, or long sleeves
  • Plain or lace trimmed hems and cuffs
  • Snap closures

Buy Thermals

You can find long underwear at local department stores like JCPenney or shop online:

  • Land's End: Choose from a nice selection of traditional waffle-weave thermals made with Thermaskin fabric to wick away moisture and preserve body heat.
  • Winter Silks: Did you know silk is a natural insulator? It is warmer than cotton and weighs less than other long underwear fabrics. Browse this wide range of silk thermal intimates for any season or occasion.

Important Features

Long underwear should be form fitting without binding or chafing sensitive skin. It should feel virtually weightless and look sleek under your clothes without riding up. Here are some key features to look for:

  • Flat-seam construction
  • Non-binding legs
  • Moisture-wicking fabrics
  • Soft elastic waists that resist rolling over
  • No-cling, no-bulk fit
  • Machine washable for easy care

Caring for Long Undergarments

Always follow the care instructions on the garment label; however, here are commonsense things you can do to extend the life of your long underwear. Wash them separately on a hand wash or gentle machine cycle or by hand. Use a mild detergent designed for hand washable apparel. Blot and roll them in a towel to eliminate excess water. Squeezing and twisting the fabric breaks down the fibers and causes the fabric to wear down over time. Lay the garments flat to dry, as hanging them could cause them to stretch out of shape. Avoid bleaching the items unless the label specifies that using bleach is acceptable.

Use these tips to maintain your plus size thermal undergarments. With proper care, they will give you years of comfortable, stylish wear.
