I started with the Action Heat socks, and had to add the base layer to my collection. It ’s just the right amount of heat in the right places to make cold winter hunting trips much more enjoyable. I highly recommend the heated base layer for anyone that spends time outdoors in the winter.

I got this primarily for motorcycling in colder weather. It works great. I can wear this with my jacket and jacket liner and I do n't have to wear other layers. I 've only used it so far riding in 50 degree weather but it was warm enough I had to turn it down or off. I usually wear a large but wanted it to fit tighter so I got a medium. The medium fits great. I would say the medium fits me perfect where normally I would wear a large t- shirt or long sleeve. Not too tight but not loose. Have n't had long enough to know how long the battery would last but have used it for a couple hours switching between high and medium and still have battery left. Would definitely use while skiing, etc

I love Smartwool base layers. The tops have cute designs and you can get matching bottoms. I wear the tops like a regular sweater with jeans in the winter and have received several compliments. We recently went to Antarctica and the base layer tops and bottom were light to pack and also warm and comfortable to wear. 👍🏻😊

Super comfy and warm! I ’ ve had my first pair for four years, wearing them just about every other day in winter, and they just got their first little hole. So, quite a sturdy garment considering how fine the fabric is. Happy to have a new pair in black.

I use this for an underlayer for road cycling. Perfect to keep dry and warm for 2 hour ride/with cold weather style jacket. The convenience of one under layer makes for an easy choice to be comfortable with the lower temps( 36 F)
5
Michael
I wore this on a recent ski trip that ranged from warm, spring- like days to true winter cold with wind and storms. The temperature regulation was outstanding across the full spectrum. It breathed well during higher- output( including backcountry) skiing and never felt clammy, yet still provided enough warmth on cold lift rides and stormy days. The fit is athletic without being restrictive, and mobility was excellent under a shell and midlayers. It layers cleanly and never felt bulky. For a single base layer to perform this well in both warm and cold conditions is impressive. I could n't have asked for more versatility or comfort from one piece.

Caden
I use this as a base layer for hiking/backpacking and sleeping in colder temperatures, it's very comfortable and warm, the only thing I dislike is where the neckline/collar sits, it almost looks and feels stretched out. It sits very low on my neck. Other than that it's amazing.

Absolutely love the lightweight fit and comfortability. It fits true to size. This is my fourth purchase of this line. Each has been exactly the same in fit and comfort. And amazingly the fabric keeps your body temperature warm yet it allows it to breathe with changing temps to create a perfect balance of core temperature.

Jeff D.
I live in the northeast part of the country and the climate is cold in the winter. I love my Smartwool base layers. I have had earlier versions of this base layer and I was able to get a newer version on sale( lucky me!!!). I tried it on and the material is super soft and comfortable.
5
Joseph M.
[ This is the best mid weight zip neck base layer I ’ ve ever owned. The quality of the fabric is unmatched. I ’ ve never had a Smartwool garment that pilled. It looks good enough to wear as a shirt/sweater. The zipper is first class and the neck doesn ’ t sag. I were it as a base layer skiing all over the IS and Canada, cycling in cold weather, and under a shirt all winter to take the North Atlantic chill of fall through spring. Best of all I can wear it without worrying about the dreaded polyester stink, its stays fresh for ages.

I bought this in the summertime, so I am looking forward to wearing this once it gets cold outside. I was concerned about this being too snug, especially in the shoulders and chest area, but it actually fit perfectly. There is ventilation in the underarm area to help with sweat. I like how the hood stays in place. I ca n't wait to try this as a base layer for cold weather- running and cross country skiing. The material is light enough to probably use for a hike in cooler temperatures.

I am using this as my second layer skiing. The front of the hoodie is substantial enough that I do n't need to wear a buff. I do wish i noticed the care instructions( lay flat to dry.) I followed the instructions. do n't know if it shrunk a bit or not in my washer; now I wish I purchased the medium. Even with all that I really like this.

Jessie C.
I love merino, but next to skin just isn ’ t for me, so I went up 2 sizes for a more relaxed fit, and it was perfect. The neck is not constricting, and the material is very soft. It ’s midweight so made for cooler weather or elevation, but I wore it out in the summer when it was mid 80s- not in direct sun all the time- and I wasn ’ t overheating. I got the navy, mink, and 2 chalk violets because it ’s hard to find any merino that works for me so stocking up!
5
Margie
I wore this top for downhill skiing and snowshoeing on some cold winter days recently. It fights well without being tight and the colors together are really pretty.
5
Sid
I love this top and have used it both as an underlayer and on its own. It is slightly dressy and has a classic look which worked well for an evening out. Based on a few comments about running small I ordered a size up. Not needed and it is a bit large: sleeves are too long and quite loose. Too lazy to exchange and have worn it several times.
5
Mary
I really like this shirt. The sleeves are long enough, although just slightly loose so it can be a bit cool on the wrists. The neck is cozy but not tight or constricting. The colours are fun.

Ellie S.
I love to buy jerseys in bright colors, and fiery coral is perfect. I 'm a small/medium in cycling jerseys, but I was really confused because reviews were telling me to size up 1- 2 sizes. I 'm 5'3 '' and 125- 135 lbs. But the Medium fit perfectly...? In fact I can fit something under this easily. My mom even tried it on and she's a similar build and it fit her perfectly. I 'm guessing it comes down to preference. If you like jerseys a little big and not as form fitting, then sizing up might not be a bad idea. But I 'm a small in Rapha, a medium in Pearl Izumi short sleeve, and also a medium in the long sleeve. I was so close to buying a large and I 'm glad I did n't.
5
Fita H.
I used to wear M, but on this one, I ordered L size, on the chest area as I expected, not too tight, and I took the risk on the bottom part, a bit loose, plus it does n't have a wide gripping area
5
Debra M.
Seems like a nice top, but even though I ordered a size larger( I know cycling jerseys run tight) I could still barely put it on. Maybe a 2XL? But Since I ca n't return it I 'll never know.
5
MaineGal
Yes, I had to size up but I love this jersey. I ’ m 117 slim athletic build 5 ’ 5 ” and I sized up to a medium. Fits through my arms and chest really well. I don ’ t find it to be baggy around the torso or waist. Fits me really well and the color is perfect. The fiery coral is perfect for fall in Maine.

Love the fabric and weight of this top. Thermal material on inside. Slim fitted fit. Nice and cozy on cool rides.

Mamaofmany
[ I am not an avid runner by any means, but I do love getting in some quality personal time by jogging a trail we made through our property in the woods. We are just starting to experience chilly mornings on the East Coast with temps in the 40's most early mornings. This hoodie is absolutely perfect this time of year. It's extremely light to wear but incredibly warm. My favorite features are the thumb holes and the hidden mittens! It is so versatile and can be something I throw on the take a run in the woods or a grocery run! The color and texture is the perfect addition to any wardrobe. I 've worn it with 3 different color yoga leggings and it looked amazing each time. The roll up hood is also something very helpful if you are anything like I am, and do n't like to have a hood bouncing and hitting your head on your run. I do n't currently use a smart watch, but having a window for one is ingenious. 5 out of 5 stars 🌟
5
AimeeE
[ This hoodie is very lightweight and comfortable to wear. It keeps me warm on a run without overheating. The material is very flexible and not bothersome or irritating while out on a casual run. My favorite feature is the folding sleeve to create a mitten around your hands. The only downside is related more to a personal preference. I tend to like slightly longer tops and this seems a tad shorter then I might normally go for, however I would say it ’s probably standard length for these types of tops.
5
BethDutton
[ I love the fit of the Notch Thermal Hoodie 2. 0. It fits true to size for a form fitting hoodie, which I love! It keeps me warm if I ’ m doing a morning run, and fits nicely so there isn ’ t anything loose hanging down when I ’ m running. I also love how it can keep me warm while not being bulky at all. The hood is also a nice addition that doesn ’ t get in the way, but is nice to have if it starts to rain during a run. It does a great job at regulating body temperature, keeping me warm while not getting me too hot or sweaty. The inside is very soft unlike other similar hoodies that are a spandex material. The odor blocking technology has worked good as this hoodie always smells fresh after washes, which can sometimes be a problem with workout gear. I wouldn ’ t change anything about the Notch Thermal Hoodie, it ’s a great hoodie for my morning runs.
5
GoodThermal
[ The Notch Thermal Hoodie 2. 0 is a new staple in my wardrobe. The fabric is warm without being bulky, allowing for layering on very cold days if needed, without restricting movement or overheating. The style is classic, so it pairs well with any style bottoms, making it easy to throw the hoodie on without having to think much about styling. For running and working out, this hoodie is fantastic! It features odor blocking technology that prevents odor buildup, and when it is time to wash this item, it is easy to throw in the wash, making this low maintenance to care for. Another favorite feature is the subtle but ingenious watch windows built into the sleeves- making it easier than ever to check stats while running/training. Finally, another handy feature is the ability to hide away the hood, for those days or stylings where you don ’ t want or need the benefits of the hood. The built in snap and loop make it easy to roll away the hood. All in all, this is a fantastic addition to my retinue of training gear, but it is also a new favorite for every day styling. It is sleek, sophisticated, and super functional.

mollyc9903
[ Awesome thermal for those chilly morning runs in Massachusetts! I love the feel of this hoodie. Its lightweight and soft, but keeps your core warm while outside. I was surprised at how well if kept me protected from the chill. This thermal is now my favorite layer when I go out for a run and even a walk with my daughter. I also love the way it has a little window for my apple watch to peek through. So far I have washed this quite a few times and it still has held it shape and looks great! My only complaint is I wish it was a tiny bit longer since I do find it short in the torso area. Overall, this is an excellent choice for those chilly morning runs, but even to have as an added layer when you are watching kid's soccer for the sidelines!

The material is soft and does not irritate, or squeeze my skin when I wear it all day. 10/10 comfy. I typically run cold, so having this in my wardrobe is an extra boost in cold weather. This is perfect for layering, and does n't add much bulk. Highly recommend!

I do n't review products often but I have had lots of Smartwool stuff and always been impressed so her goes: So far this garment is awsome. The wieght allows it to be worn as a primary layer or under a shell. Medium fits me perfectly at 70 '' and 170 lbs with a light liner underneath. The hood fits tight when in use, maybe too tight, we 'll see. after I break it in. It also covers the chin and mouth area when pulled up. It could use a chest pocket. I will be using it during a golf trip toi N Ireland with temps in the 50's and 60' with wind and rain; part of. a layering system I 'm bringing.
5
Olga
This is my favorite brand. This model is the best. It has a high collar that immediately turns into a hood. It's very comfortable. The neck is always covered. The elbows are very well designed. They have special fabric inserted in them, so the elbows do n't stretch out. I highly recommend it.
5
Steve
I use this as a base layer on the mountain teaching skiing, and just on its own running when the temperatures are 35 or below. It feels super good, and the thumb holes and hood are beautifully designed. I 'm buying another. It just feels like the best piece I own.

Used it only a few times so far. If you want to stay warm when wearing it, you 'll need something to break the wind. Awesome for high output activity. Kept me warm in the rain at soccer practice!

Wear this top for casual and hiking. As other reviews have said- you do have to be careful not to snag. That said, it looks and feels great! I had four from prior year and liked well enough to buy another.
5
Kate
The negative reviews that say this top snags are NOT wrong. However, the benefits far out way that one problem. I already owned four when I purchased this one so was aware that I would need to use some caution. BUT it is lighter, softer and dressier than the other Smartwool long sleeved tops so it is perfect for home, office, going out, etc. It does run large. In any other base layer I would be a small or in some cases a medium. The xsmall was perfect as it did n't hug my body too tight- just a more relaxed fit. Love it and would buy more if they come up with more colors.

I 've had this shirt for a few days and have already used it for hiking, cycling, and a cozy layer around the house. It's a great weight and very breathable. I usually wear a medium and got a large for a looser fit, which worked well!

Like the feel of this LS tee. Can use it as a base layer or by itself on cooler days. I personally used it for an outdoor run and felt great. One thing though… while the fabric is intended to wick sweat out, I did notice the tee being soaked so not sure I ’ ll be taking it out for runs again. The length of the tee is also a little short so consider that if interested in this shirt.

So far I have not been let down, 1st layer of business taking care of my stinky sweatiness and keeping me toasty. I 've worn it on 10° days and in the 40's as well and love it so far. I 'm going to definitely purchase a few more for sure!

Frequently Asked Questions For Thermal Shirts
Thermal shirts are designed to provide warmth and insulation during colder weather. They are typically made from materials that trap heat while allowing moisture to escape, keeping you dry and comfortable. The construction often features a snug fit to enhance heat retention without adding bulk.
Thermal shirts are often made from a variety of materials, including synthetic fibers, wool, and blends that combine both. Wool, particularly merino wool, is known for its excellent insulation and moisture-wicking properties. Synthetic materials, on the other hand, are lightweight, durable, and quick-drying, making them popular for active use.
Thermal shirts are versatile and can be used for a range of activities, including outdoor sports, hiking, skiing, and everyday wear in cold weather. They provide a great base layer for layering under jackets or other clothing, ensuring you stay warm during various activities. Their moisture-wicking properties also make them suitable for high-intensity workouts in cooler temperatures.
When selecting a thermal shirt, consider factors such as the intended use, climate, and fit. For high-intensity activities, look for lightweight, moisture-wicking options, while for casual wear or low-intensity activities, a heavier, more insulated shirt may be preferable. Additionally, pay attention to the fit; a snug fit is ideal for layering, while a looser fit may offer more comfort for casual wear.
Most thermal shirts can be machine washed, but it's important to check the care label for specific instructions. Generally, using a gentle cycle with cold water and avoiding fabric softeners can help maintain the shirt's performance and longevity. Air drying is often recommended to prevent shrinkage and preserve the material's integrity.
