Best Thermal Underwear for Women


 

 

Thermal underwear is a type of clothing worn beneath your top layers to keep your body warm, especially during harsh winter temperatures. Made from specialty fabric to protect against the cold, women’s thermal underwear traps body heat to provide warmth.

 

Start by reading these general tips on packing for winter travel:

 

The best thermal underwear for women often feature popular and recommended fabrics, such as merino wool and polyester blends, because they are lightweight, ultra-warm, and wick away moisture. Outdoor brands specifically choose certain fabrics that are ideal for traveling in the winter.

 

Another smart traveler secret is to re-wear clothing more than once without washing. Read more tips about this strategy here!

 

 

How to Choose the Best Thermals

 

The best thermals are made from merino wool or silk fabric because it wicks away moisture, it’s lightweight, and ultra-warm.

 

People love these fabrics for travel!

One of the biggest benefits of traveling with clothing made with merino wool is that it can be reworn several times without washing. Some travelers have even gone weeks wearing it repeatedly without washing it!

Due to this reason, you only need to travel with one pair of woolen thermal underwear on a trip helping you pack light yet stay extremely warm.

The biggest downside with merino wool and silk thermal underwear is the price. Because they’re high quality materials, they are high in price but well worth it. All you need is one pair! Keep an eye out for sales.

Synthetic blends are a less expensive option. Although not quite as effective as natural fibers, they’ll definitely help keep you warmer than not having them at all.

 

Keep in mind that cotton is the least effective fabric for winter under clothes such as thermals. It absorbs moisture, preventing your clothing from helping you stay warm.

When it’s really cold out, I put the leggings under it – those are not constricting at all. I walked all over New York City in below freezing weather and I was warm. Soft, comfy, and hand wash well. The shirts are terrific, and the leggings are excellent under other leggings or pants.

A Cuddl Dud crew or a a neck, with a button up shirt and a merino sweater was perfect for very cold weather urban sightseeing. Ditch the button up shirt for normal cold, add a decorative scarf, and stay toasty!”

I would also recommend their socks and undies, if you want to go for a full-wool ensemble. They’re some of the best extreme cold weather thermals.

In terms of style and weight, I find myself reaching for the Icebreaker Everyday Long Underwear Leggings in 200gm and the Oasis Long Sleeve Crew in 200gm. If I could add anything to my Icebreaker collection, it would be the Tech Top Long Sleeve Half Zip.”
