How to Choose the Best Women's Hiking Underwear

Wearing the right underwear when hiking is pretty important. It keeps you warm, it keeps you dry, it keeps you comfortable. But there are so many to choose from! That’s why we researched some of the top-selling products and most popular brands to put together these women’s hiking underwear reviews to help you find the right pair for you. Before we get started, let’s take a look at some of the key features you need to know about before you shop.

Best Women's Hiking Underwear

Age: Most of these are women’s sizes but we also included a couple of options for young girls. In fact, the size range covers toddler sizes through school aged girls. They even come in a variety of colors, including white, grey, and pink.

How to Choose the Best Women's Hiking Underwear

Fitextreme Maxheat Underwear

Review
Fitextreme Maxheat Underweaar is available as a shirt, a pair of long johns, or a set that includes both. Both the top and bottoms are lined with premium fleece material that’s smooth, soft, and keeps you warm in cold weather. It also has flat, secure seams to prevent anything from rubbing against your skin. In addition to superior thermal retention, this material also has effective sweat wicking properties to help you stay dry. Plus, it’s really lightweight and quick drying just in case you do get wet. Although both the top and bottoms have a compression fit to keep it from being too bulky, the four-way stretch material on the outside allows for plenty of freedom of movement. Choose a shirt, pair of bottoms, or a set of both. They’re all available in black, light gray, and dark gray.

ColdPruf Base Layer Top

Review
This ColdPruf Base Layer top is the best thermal underwear for cold weather hiking that we found in our research. The ring spun cotton material is super soft and comfortable and rated for low to medium activity in cold to very cold weather. It’s tagless and has flat seams that keep anything from rubbing against your skin which can be really annoying, especially when you’re wearing it as a base layer and have another top and jacket over top of it. Another good thing about this shirt is the fit. It’s designed with an athletic, comfortable fit that’s snug enough to eliminate any bulk while still allowing comfortable movement. With an athletic front and back rise and extended body and sleeve length, this shirt provides the right amount of coverage for cold weather adventures.
