Hey everyone, if you’ve ever stood in a clothing store staring at a rack of women’s knitted jackets and coats, wondering if that soft, lacy-looking knit is actually gonna keep you warm enough for winter, you’re not alone. As someone who’s been in the women’s jackets and coats supply game for years, I get tons of questions from both customers and small boutique owners about this exact thing. Let’s break it down straight, no fancy jargon, no BS—just the real deal on whether knitted layers actually fight off the cold. Women’s Jackets and Coats
First off, let’s get one myth out of the way right now: a lot of people think knitted stuff is only for spring or fall, that it’s too thin to handle real winter. Nah, that’s not true. The warmth factor of any knit depends on two big things—how it’s made, and what yarn you’re using. Let’s talk yarn first, because that’s the backbone of it. We use a mix of wool, merino, even some blends with recycled poly now, right? Wool, especially merino, is magic because those tiny scales on each fiber trap air. Air is a way better insulator than fabric itself—think about why a down jacket works, it’s all the little pockets of air holding heat. Knitting is perfect for that because it creates way more tiny air pockets than a flat woven coat or jacket. Woven fabric is tight, so air can’t get stuck; knit has those little loops that hold heat in, and let moisture out too, which is a bonus. I’ve tested this myself—last winter, I wore a thin merino knit jacket under a denim coat when I was running errands at 20 degrees F, and I was way warmer than when I wore a thick woven cotton jacket. The knit held my body heat way better because it didn’t let all that warm air escape.
Wait, but not all knits are created equal. That’s where the knit structure comes in. A tight, dense knit like a jersey or a rib knit is way warmer than an open, lacy knit that you’d wear to a brunch in the fall. We make a lot of our women’s knitted coats with a double-knit structure, which is like two layers of knit woven together, so extra air trapped in between. Those are the ones people reach for in December, y’know? Then there’s cable knit, which is super trendy right now—those twisted stitches create even more texture, more little air pockets, so that’s a warm one too. I had a boutique owner reach out to me last month saying her customers were sleeping on our cable knit coats because they thought they looked too “fancy” for cold weather, but once they tried them on, half the store sold out in a week. Makes sense, right? The chunky, tight cable loops don’t let wind get through, and hold heat like a hug.
Now, let’s address the elephant in the room: what about when it’s damp? A lot of people say knitted stuff gets cold when it’s wet, which is true—but that’s not a knit-specific problem, that’s a fabric problem. Wet cotton gets way colder than wet wool or merino. Merino, specifically, has natural wicking properties, so it pulls moisture away from your skin, and even when it’s damp, it still holds most of its insulating power. I did a test last year where I sprayed a small section of our merino knit jacket with water, and the rest was still warm to the touch, whereas a cotton woven jacket we had got ice cold in 10 minutes. Now, if you’re out in a heavy rainstorm, no knit is going to keep you dry—you’d need a waterproof outer layer for that—but for light snow, mist, or even just sweat from walking around the city, our knits handle that way better than most woven jackets. That’s why a lot of commuters love our knitted coats—they’re light enough to carry when you’re on the bus, but warm enough when you’re walking from the stop to the office.
I also hear a lot of women say, “I don’t want a bulky coat, I want something that looks good but doesn’t make me feel like a marshmallow.” That’s where knit really shines. We can make our women’s knitted jackets with medium weight yarns that are warm but not puffy. A lot of woven winter coats have that thick lining that makes them look boxy, but knit has stretch, so it fits to your body, traps heat close instead of letting it escape, and looks way more polished. Last season, we launched a slim-fit rib knit jacket that ended up being our top seller because women would wear it to work, then out to dinner, and it never made them feel like they had to hide under a blanket. One customer left a review saying she used to layer three woven sweaters under her coat, but now she just wears our knit jacket and it’s the same warmth—game changer, right?
Wait, let’s talk about a common mistake people make: not layering right with their knit jacket or coat. A lot of people grab a knit jacket and think, “that’s enough,” but if it’s super cold, you still need a base layer. But that’s not the knit’s fault—any coat, woven or not, needs layers in frigid temps. The best part about knits is they work with almost any base layer. If you use a thin, moisture-wicking base under your knit jacket, you’re not trapping sweat against your skin, so you stay dry and warm. I’d rather have a merino knit jacket + a thin thermal than a thick woven coat + a heavy sweater—because the knit holds the heat closer, and doesn’t add all that extra bulk. I’ve seen so many women switch to knit layers and cut their coat buying in half because they work for so many occasions.
Now, let’s be real—there are some knits that aren’t great for cold weather. Super fine, open knits like lace or pointelle? Those are for mild temps, like 40-50 degrees F, not winter. That’s why we label our products clearly—we don’t sell an open knit as a “winter coat,” we make specific warm knits for cold days, and lighter knits for transitional weather. That’s a big mistake a lot of suppliers make—they throw any knit on a rack and call it warm, but we test every one of our products in our own offices and even outdoors to make sure the warmth matches the description. Last year, a new supplier hit our market with a cheap acrylic knit coat that advertised as “warm” but customers were complaining it was colder than a windbreaker. We turned down that whole line immediately because we didn’t want to mislead anyone—our customers (the boutique owners and the women shopping) trust us to get this right.
I’ve also noticed a trend lately where people are going for more sustainable layers, and knits fit right in. Wool is renewable, if you get it from responsible farms, and a lot of our knits are made with recycled yarns now. Woven coats often use synthetic linings or fabrics that don’t breathe, which can make you sweat and then get cold when you stop moving. Knit breathes way better, so you don’t get that damp, clammy feeling, which actually helps you stay warm longer. That’s a huge plus for anyone who’s active—walking, hiking, running errands—because you don’t have to take your coat off every 10 minutes because you’re sweating through it.
Wait, let’s share a quick personal story. Last year, I went to a trade show in Minnesota in January. It was like 10 degrees F out, super windy. I wore one of our double-knit wool coats, a thin base layer, and jeans. A friend of mine was wearing a thick down woven coat, and she was complaining the whole time about how cold she was, while I was totally fine. At first, she was like, “No way, that’s just a knit coat, how are you not freezing?” I showed her the label—our coat has a 400g weight, which is the same as a lot of mid-weight down coats, but way less bulky. That’s when she realized I wasn’t lying, knits actually can hold that kind of warmth. It’s not magic, it’s just the way the loops trap air—air is the best insulator we have, and knit is made to hold as much of that as possible.
Now, if you’re a boutique owner reading this, or a woman looking to stock up on warm women’s knitted jackets and coats, let’s be clear: it’s not a gimmick, it’s a functional, stylish layer that works. A lot of people sleep on knits because of old stereotypes, but that’s just because they haven’t tried a well-made one. We’ve been refining our knit designs for years, testing different yarns and structures, and we can tell you firsthand that the right knit coat will keep you warmer than a cheap woven coat any day.
