10 Best Base Layers at Amazon Under $25

Once the temperature drops to “feels like 5 degrees” territory, I refuse to leave my New York apartment without wearing at least three layers of clothing. Warm and cozy base layers are the workhorse of my winter wardrobe—I’ll pile on thermal tights and fleece-lined leggings under any wide-leg pants, and always have a long-sleeve shirt on before I pick out a chunky turtleneck to top it off. After a decade of New York winters, I’ve learned the hard way that packable, warm-yet-lightweight layers like these are non-negotiable.

Whether you’re looking for a moisture-wicking turtleneck or toasty, fleece-lined long johns, Amazon’s got you covered with hundreds of affordable options—some of which are on sale up to 60 percent off. To help you narrow it down, I’ve found 10 comfy and cozy base layers that won’t break the bank. Read on for my top recommendations, all under $25.

Lands’ End Thermaskin Turtleneck

Lands’ End is a favorite brand for outdoor essentials among T+L editors and travelers alike, and this turtleneck top is no exception. It’s crafted from the brand’s proprietary Thermaskin material, a thick jersey fabric that’s buttery- soft and smooth, which generates heat by absorbing body moisture. The innovative material is moisture-wicking and will help to keep you warm and dry all day long, whether you’re hitting the trails or walking the dog. “As soon as I put this on, I immediately ordered two more! Why? Because it is so wonderfully warm without any bulky thickness,” raved one five-star reviewer. 

Ekouaer Long-sleeve Thermal Shirt 

Prefer a lower neckline? The Ekouaer Long-sleeve Thermal Shirt cuts a flattering figure with a graceful boat neck, which comes in nine shades, including classic black and an eye-catching burgundy hue. This fitted top is notably soft, earning its spot in many shoppers’ winter wardrobes. “I wear it at least once a week, and it still looks just as good as the day I bought it,” raved one shopper, who called the top “one of my absolute wardrobe staples.” They praised the material, writing, “It is so soft, the kind of fabric you actually look forward to putting on. Even after multiple washes, it hasn’t faded or lost that buttery feel.” Best of all, it’s currently 60 percent off.

X-Cheng Fleece-lined Sheer Tights 

I swear by fleece-lined tights all winter long, layering them under skirts, wide-leg pants, and just about anything else. I’m always on the hunt for a pair that’s both sheer and warm—somewhat of an oxymoron, until I found the X-Cheng Fleece-lined Sheer Tights. Currently 38 percent off, these are a fan favorite thanks to their semi-sheer look, remarkable durability, and overall warmth. “I’ve owned several pairs over the years, and they’ve held up really well,” wrote one repeat customer, who added, “These fleece-lined tights are perfect when you want the look of sheer tights but need real warmth.”

Sampeel Thermal Long John Set

For pajama-worthy softness, look no further than the Sampeel Thermal Long Johns, a cozy two-piece set that’s comfy enough to wear all day long. Whether you’re layering them under your ski gear for a day on the mountain or sipping hot cocoa by the fireplace at the lodge, this cloud-like thermal underwear set is made to keep you warm on the go. Now 20 percent off, they’re a total steal for just $20. Shoppers rave that they’re exceptionally warm for how lightweight the material is. “They honestly exceeded my expectations,” wrote one reviewer. “They keep the heat very well without feeling heavy or uncomfortable. The material is soft, fits perfectly, and doesn’t feel tight.”

JZCreater Thermal Underwear Set

With over 1,000 positive reviews, the JZCreater Thermal Underwear Set is a go-to style for warmth and comfort. “I bought these for a snow trip, but might wear these as pajamas too,” wrote one shopper. The two-piece set includes a long-sleeve shirt and cozy leggings that are crafted from an ultra-soft polyester blend that’s both moisture-wicking and breathable, ensuring these are comfortable enough to sleep in. The duo is designed to feel like a second skin, but some shoppers preferred to size up for a less-fitted look. I love that the set comes in a wide range of sizes as well, ranging from XS to 3L.

Devops Thermal Long-sleeve Shirt 2-pack 

Now marked down to its lowest price in 30 days, the Devops Thermal Long-sleeve Shirt Set is an excellent value, with each top ringing in at just $10. Stock up on two of the same color, or switch it up with a black top and a striped shirt. The soft, fleece-lined fabric is thin enough to layer, yet it retains heat remarkably well. “The fabric is soft and cozy, providing the perfect amount of warmth during chilly days,” wrote one repeat shopper, who praised how well the shirts have held up over time. “After countless washes, the fabric hasn’t pilled or lost its shape.”

Spyder 2-piece Thermal Underwear Set 

Crafted from brushed fleece, this set of thermal underwear from Spyder is designed to fit snugly and layer easily under heavier winter gear. The soft, silky material feels nice against bare skin, and the elastic waistband stays in place throughout the day without digging in. Shoppers love how lightweight yet toasty this set is—one shopper even tested the set in -1-degree weather while working outdoors. “I was able to comfortably stand outside in the cold, and the quality of the material is great,” they said.

Fullsoft High-waisted Leggings 

Compressive and figure-flattering, these high-waisted leggings are a perfect layer for everyday wear, whether you’re throwing them on under snow pants or wearing them on their own to a yoga class. They’re crafted from a thicker polyester blend that’s fully opaque, providing an extra layer of warmth without adding any bulk to your outfit. With over 17,000 positive reviews, it’s easy to see why they’re such a popular choice–especially now that they’re marked down to just $7. “The fabric truly lives up to the ‘‘buttery soft’ name—they feel smooth and cozy against the skin,” wrote one five-star reviewer. “They’re stretchy but still hold their shape nicely,” they added, noting that the “high‑waisted fit is flattering and gives a nice smoothing effect around the waist and tummy.” Best of all, the smooth waistband stays in place all day long, so you can move freely without having to constantly readjust. 

Paralinda Fleece-lined Thermal Tights

Sometimes, only a thicker pair of leggings or tights will do—and the Paralinda Fleece-lined Thermal Tights are a reliable wardrobe staple for those chilly days. For just $8, these fleece-lined tights are substantial enough to wear on their own under a dress or loose pants, offering ample warmth without sacrificing your style. One shopper wrote that they “really help keep me warm without adding too much bulk.” Crucially, the high-waisted waistband doesn’t slip down, so you can wear them with confidence while sightseeing, lounging at home, or bundling up for a winter walk. 

Ekouaer Women’s Thermal Turtleneck Shirt 

This seamless mockneck is soft and stretchy, making it a perfect layer to wear on its own or under your favorite sweater. The polyester and spandex blend is breathable and lightweight, so you won’t overheat even if you’re bundled up. “The material is so soft, and the shirt maintained its quality even after washing,” raved one shopper. While neutrals are ideal for mixing and matching with the rest of your wardrobe, I love that this mockneck comes in 12 different colors—and at just $15 each, you can stock up on a few to pair with different outfits.
