Hey everyone, it\u2019s Jake here\u2014co-owner of the cooling vest brand you\u2019ve probably seen popping up in worker gear and outdoor adventure groups lately. I get so many questions DMed to my team every week, and one that never fails to come up is: \u201cCan I layer a cooling vest with other thermal clothing?\u201d Honestly, this is such a great question because most people think cooling gear and thermal gear are like oil and water\u2014they should never mix, right? But after years of testing this stuff with industrial workers, pro athletes, and even folks who just hate being sweaty while hiking in the mountains, I\u2019m here to tell you it\u2019s way more nuanced than that. Let\u2019s break it down like we\u2019re chatting over a post-work beer, no stuffy textbook jargon. Cooling Vest<\/a><\/p>\n

<\/p>\n

First, let\u2019s get one thing straight: \u201cthermal clothing\u201d isn\u2019t just one type of gear. A lot of people throw that term around to mean anything that keeps you warm, but it actually covers a whole range, from thin base layers to heavy winter jackets. And cooling vests? They\u2019re not just for the beach or hot yoga\u2014they come in so many forms too. There\u2019s the phase change material (PCM) ones that stay cool for hours, the evaporative ones that soak up water and let it wick away heat, and even the mechanical ones with small fans that blow air through the fabric. Each of these plays really different with thermal layers, so you can\u2019t just slap any old thing on top and call it a day.<\/p>\n

Let\u2019s start with the low-hanging fruit: when you should definitely NOT layer a cooling vest with thermal stuff. If you\u2019re talking about a thick, puffy winter jacket or a heavy fleece layer that traps 99% of your body heat, don\u2019t waste your time. Why? Because cooling vests work by moving excess heat away from your core\u2014their whole job is to let your body breathe. A thick thermal layer, especially one that doesn\u2019t wick moisture well, will block that airflow. Even worse, evaporative cooling vests need that water to evaporate to work, and a thick thermal layer will trap the wetness right next to your skin, making you feel clammy and way colder than if you\u2019d just worn the thermal gear alone. We had a worker at a steel plant test this last winter\u2014he tried wearing a PCM cooling vest under his heavy work parka, and within 20 minutes he was complaining about shivering and sweating through his shirt. Turned out the parka blocked all the cool air from the vest, and the vest\u2019s cooling effect had nowhere to go. Lesson learned: if your thermal gear is meant for temps below 40\u00b0F (4\u00b0C), skip layering a cooling vest underneath it. You\u2019re just wasting money and comfort.<\/p>\n

Now, the good stuff: when layering works like a charm, and the right ways to do it. Let\u2019s talk base layers first\u2014these are the thin, close-fitting layers you wear right against your skin, and they\u2019re where magic happens when paired with a cooling vest. For cool temps (say 50\u201365\u00b0F \/ 10\u201318\u00b0C), a moisture-wicking base layer is your BFF. We recommend lightweight polyester or merino wool (not cotton\u2014cotton stays wet forever) because it pulls sweat away from your skin, which plays perfectly with both PCM and evaporative cooling vests. The base layer doesn\u2019t block the cooling vest\u2019s airflow, it just keeps your skin dry so the vest can do its job better. A lot of hikers and construction workers swear by this combo: base layer \u2192 cooling vest. Wait, why the cooling vest over the base layer? Because putting it on top lets the cool material make direct contact with the base layer\u2019s moisture, which speeds up evaporation. If you put the vest under the base layer, it can\u2019t reach the sweat as well, so the cooling effect is weaker. I tested this myself last month on a 55\u00b0F fall hike\u2014wore a thin merino base layer, our PCM cooling vest over it, and a light windbreaker on top. I was sweating when I started, but the vest kept my core cool the whole time, no chills, no overheating. That\u2019s the sweet spot right there.<\/p>\n

What if it\u2019s a little chillier, like 40\u201350\u00b0F (4\u201310\u00b0C)? Can we add an extra layer over the cooling vest? Here\u2019s the catch: it has to be a breathable outer layer, not a thick insulating one. We\u2019re talking light fleece pullovers or thin wind-resistant shells\u2014nothing puffy. The key here is that the outer layer has to let the vest\u2019s cool air escape, not trap it. A lot of people ask if they can layer a mid-layer over a cooling vest, and the short answer is yes, but only if that mid-layer is breathable. I work with a group of pro trail runners who do winter ultramarathons, and they all wear our cooling vests under thin windproof fleeces. Why? Because when they\u2019re running hard, they generate a ton of body heat, the vest pulls that heat away, and the thin fleece blocks wind but doesn\u2019t stop the cool air from moving. If they wore a heavy down jacket over the vest, they\u2019d overheat within a mile. But a light fleece? Perfect balance.<\/p>\n

Now, let\u2019s get into the science behind why this works, because I know some of you nerds (I mean that in a good way) want the deets. Cooling vests, regardless of type, target your core temperature\u2014your chest, back, and abdomen, which are where your body generates the most heat and where your vital organs are. Thermal layers, when chosen right, don\u2019t insulate that core too much, so the vest can still do its thing. PCM cooling vests, for example, have waxes that melt when your body hits a certain temp (around 90\u00b0F \/ 32\u00b0C) and solidify when you cool down. That phase change process works best when there\u2019s a thin, porous layer between your skin and the vest\u2014your wicking base layer lets the heat transfer through, so the wax can melt properly. If you have a thick layer, that heat can\u2019t reach the wax, so the vest doesn\u2019t activate. Evaporative vests work by having water evaporate off the fabric, and that process cools the air next to your skin. A breathable base or mid-layer lets that air circulate, while a thick layer stops it dead. We did a test last year with a thermal camera\u2014you could see the area under the cooling vest being 5\u20137\u00b0F cooler than the rest of the torso when layered with a thin base layer, but only 1\u20132\u00b0F cooler when layered with a thick fleece. That\u2019s a huge difference for comfort.<\/p>\n

Wait, what about the flip side? Can you wear thermal gear over a cooling vest in cold weather? Let\u2019s clarify: if it\u2019s cold but you\u2019re active\u2014like working in a warehouse where the heating is spotty, or skiing hard\u2014yes, you can layer a thin thermal outer layer over a cooling vest. But if you\u2019re sitting still in cold temps, like a night shift at a construction site in 30\u00b0F (-1\u00b0C) weather, no. When you\u2019re inactive, your body doesn\u2019t generate as much heat, so the cooling vest can actually make you too cold if it\u2019s covered by thermal gear. Our team had a guy test that last winter: he was working a 12-hour shift in a cool warehouse, wore our evaporative cooling vest under a thin thermal vest, and stayed at a comfortable 72\u00b0F core temp the whole time. No shivering, no overheating. But when he tried the same thing on a day off, sitting in his apartment, he took off the thermal vest after an hour because he was freezing. That\u2019s all about activity level\u2014if you\u2019re moving, you generate enough heat to balance the cooling vest, so a thin thermal outer layer works. If you\u2019re not moving, skip the extra layer, or get a cooling vest with less cooling power for cold temps.<\/p>\n

I also get a lot of questions about common mistakes people make when layering. First, don\u2019t wear cotton under or over a cooling vest. Cotton holds moisture like a sponge, so if you sweat through the base layer, it stays wet and makes the vest less effective, and also feels gross. We had a lifeguard test this last summer\u2014wore a cotton t-shirt under his cooling vest, and after a few hours, the t-shirt was soaked, the vest couldn\u2019t cool him down, and he was way more uncomfortable than the guys wearing merino base layers. Second, don\u2019t overlap layers too much. If you have a thick base layer, a cooling vest, and a thick mid-layer, that\u2019s three layers blocking airflow, and you\u2019ll get overheated fast. Keep the layers as thin as possible, and make sure each layer is designed to work with moisture. Third, test it before you rely on it. What works for me might not work for you\u2014if you\u2019re going on a long hike, wear the layers you plan to use on a short test hike first. That way you can adjust if it\u2019s too hot or too cold, and avoid surprises mid-adventure.<\/p>\n

Another thing to mention: not all cooling vests are created equal for layering. The cooling vests we make are slim-fit, so they don\u2019t add bulk when layered, which is a big deal for people who need to move around a lot. If you get a bulky, puffy cooling vest, adding thermal layers on top will make you feel like a marshmallow, and it\u2019ll block airflow too. Slim, low-profile cooling vests are way better for layering, in my opinion. We designed ours specifically to be flexible, so construction workers can bend over to lift boxes, hikers can climb rocks, and athletes can run without feeling restricted. That slim profile makes all the difference when you\u2019re adding thermal layers.<\/p>\n

Let\u2019s wrap this up with a quick cheat sheet, because I know you\u2019re going to forget all this by tomorrow:<\/p>\n

    \n
  1. Never layer a thick insulating thermal jacket\/parka over or under a cooling vest (works only for temps above 40\u00b0F \/ 4\u00b0C, and only if it\u2019s breathable).<\/li>\n
  2. Always pair a cooling vest with a moisture-wicking base layer (polyester or merino wool, no cotton). Wear the cooling vest over the base layer for best performance.<\/li>\n
  3. For temps 40\u201365\u00b0F (4\u201318\u00b0C), you can add a thin, breathable mid-layer (light fleece, thin wind shell) over the cooling vest, but skip thick puffy layers.<\/li>\n
  4. If you\u2019re inactive in cold temps, skip extra thermal layers over a cooling vest\u2014stick to just the base layer and the cooling vest.<\/li>\n
  5. Test your combo before using it for long periods, especially if it\u2019s for work or a big event.<\/li>\n<\/ol>\n

    At the end of the day, layering a cooling vest with thermal gear isn\u2019t a \u201cyes or no\u201d question\u2014it\u2019s a \u201chow, when, and what types\u201d question. We\u2019ve spent years testing this with people in all kinds of industries and activities, and the number one mistake we see is people thinking they can wear any thermal gear with any cooling vest. But when you pair a slim, well-designed cooling vest with the right thin, breathable thermal layers, you get the best of both worlds: no overheating when you\u2019re active, no shivering when it\u2019s a little chillier, and way less sweat-soaked discomfort.<\/p>\n

    <\/p>\n
