Uniqlo Heattech Crew Neck Long-Sleeve T-Shirt And Leggings

USERS SAID: "These leggings are lightweight and super comfortable! Since the material is on the thinner side, I wouldn't wear them in place of pants, but they'll be great all winter with dresses and under pants as an added layer."

HELPFUL TIP: The thin fabric and body-forming fit make this t-shirt and legging set perfect for slipping underneath your work attire on extremely cold days. 


L.L.Bean Silk Pointelle Long-Sleeve Scoopneck and Pants

LOVED FOR: The 100% pointelle-knit silk feels virtually weightless underneath your clothing. 

USERS SAID: "I like these because they provide just the right amount of extra warmth for outdoor traveling. They aren't bulky and are comfortable. They really are essential in my wardrobe."


Thermajane Fleece Lined Thermal Underwear Set

LOVED FOR: This lightweight set conforms to the shape of your body so you don't have to worry about any uncomfortable bunching or gathering.

BEST FOR: This is a tagless design, so it's great for those with easily irritated skin. 


Cuddl Duds ClimateRight Stretch Fleece Long Sleeve Crew And Underwear Leggings

WHY YOU NEED IT: Made of a textured stretch fleece, this set provides both comfort and warmth. 

USERS SAID: “I love these! They breathe so you don't get sweaty but you are still warm. My favorite part of them is that they have soft stitching. I have purchased other brands and they aren't as soft and the stitching constantly irritates my sensitive skin. They also have thumb holes which I like, it helps keep my hands warmer in negative temperatures.”


Ekouaer Long Thermal Underwear Base Layering Set

USERS SAID: “I know these are going to take me through the winter. They were EXACTLY what I was looking for. So soft, perfect amount of stretch, and somehow they don't attract as much cat hair as I thought they might.”

BEST FOR: Whether you’re venturing into the cold or staying tucked into bed, this set will keep you soft and comfortable.


Under Armour ColdGear Authentic Mock Neck Top & Bottom

BEST FOR: The 4-way stretch allows for maximum movability, making this set ideal for action-packed winter days.

USERS SAID: “Worth every penny. Extremely comfortable, breathable and of good quality. I wore this and sometimes only this under my winter coat in Colorado when we went skiing earlier this year. It kept my upper body very warm and was slimming as well.”


Sweaty Betty Free Style Seamless Base Layer Top & Bottom

WHY YOU NEED IT: With the fun print from head to toe, you won’t want to cover up this base layer. Show it off while you’re lounging around before hitting the slopes!

LOVED FOR: The flattering fit that’s as warm as it is cozy.


SmartWool NTS Mid 250 Pattern Zip Top & Bottom

WHY YOU NEED IT: Made with 100% Merino wool, this set is built for extreme warmth without being too thick.

USERS SAID: “These are the best! I have ordered more. They are expensive but soft and never itch and I like that they are longer than the competitors.”


Minus33 Midweight 1/4 Zip & Bottom

USERS SAID: “I LOVE this top!!! I purchased it as a layering piece for cold-weather backpacking but I find myself just wearing all the time because it's so snuggly and warm.”

LOVED FOR: This 1/4 zip-top and bottom set is not too tight and not too loose, it's just right.   


Duofold Mid Weight Wicking Thermal Shirt & Bottom
