[ These cycling tights do exactly what they 're supposed to do. The sizing may run a touch small so you may need to size up if you 're on the cusp of sizing. I 'm 5' 2 '' 125 pounds and the small is a tiny bit more snug than I 'd like but they may stretch out over time. I use these for mountain biking and I 'd recommend them for rides 40°F and under. Great quality!

[ I could go on and on about this whole line from Smartwool. It's their best thing in a very long time and I 've been a fan for years. The material is very soft, has a great but comfortable fit. These bottoms also have a nice wide and sturdy waste band so there is no bunching or other uncomfortable nonsense in that area. These are very warm, so perfect under a shell pant or bib for alpine skiing, but I do n't think I would wear them on a tour.

This is a great product. I purchased one for myself on- line for Christmas, based on the previous smart wool base layer bought in the store in October 2024. The only problem is that the shoplifting tag was still on the product when I opened it on Christmas Day 2025. How Annoying!!!!!! Now I have to return the product. How about some quality control? This was a very unsatisfying purchase.

Theperfecthoodieforfall
[ This hoodie is great. It is warm but not hot. Super soft, some tech shirts can be itchy but this is not! I wear it all the time and it works great for all kinds of things even casual. I love the thumb holes and how it has two sets so you can cover your hands as needed the sleeves are also perfect for me. Usually sleeves are short as I am 6 ’ but even in the back thumb holes it is not tight. It is very breathable and flexible which keep it from impending motion. I love it and will be using it a lot.

Alec
[ This jacket is warm despite how light it is. I don ’ t think it ’ ll hold up once it gets too far below freezing, but I ’ ve been running in around 40 degree Fahrenheit weather and I ’ ve had no problem staying warm. I like the thumb holes in the jacket to help keep my hands warm, even if I eventually will start wearing gloves anyway once it gets colder. Those holes are helpful when it ’s the end of fall/beginning of winter. On top of the functionality, the jacket also looks very sleek and forms to the body well. I ’ ll probably wear this casually every once in awhile as well because it looks that good. Only complaint I have is with the hood. Luckily it ’s fairly light so it ’s not too distracting, but it ’s still a pain to go out for a run with my hood bouncing around. You can tuck the hood with the strap that comes with the jacket, but that ’s still a pain( albeit a small one) to roll up and even then it ’s not a perfect solution. Overall, I highly recommend this jacket! Definitely a keeper for my workout outfit rotation.

Nick
[ Brooks made a really nice quality hoodie. The material is a cross between athletic moisture wicking type and a thermal ribbed type. Material is fairly thin, but provides surprising warmth due to thermal ribs. It ’s great for running or outdoor exercise in cooler temperatures. I ’ ve been wearing it more as casual work/everyday attire. It provides about as much warmth as a long sleeve thermal shirt. I wouldn ’ t wear it in extreme cold but works well as a mid layer when temperatures are down. The thermal hood can be rolled up if you ’ re not using it. Medium size fits a 5 ’ 6 ”, 160lb male with athletic build very well. Sleeves and torso length are just right. Slightly form fitted with room for movement. Material is elastic and stretches. Zipper stash pocket and thumb holes are nice features. I ’ m very happy with the look and feel of this hoodie and would recommend to anyone looking for a nice athletic type hoodie.

[ I must say I ’ ve really enjoyed this shirt! The material is amazing! Warm enough but breathable with a great four way stretch in it! It ’s very comfortable and a perfect base layer when it needs to be! I also love the hood, it ’s shaped to my head, not tented or baggy. Fit is more on the fitted side but not so much that I ’ d size up just doesn ’ t have any loose areas. Love it! Definitely will buy more of these!

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.

I love these for layering or just on their own. The dark red color and the zipper make it cute enough to wear as a sweater, plus it ’s super comfy and warm.

I live in Florida and use this for winter trips to NY and for winter hiking.

[ I bought this several weeks ago and have worn it on several chilly( and hilly) NE dog walks. It provides a warm, yet breathable layer under my light down jacket.

DreambornAnthology
Love Smartwool for days in the snow. It ’s a great base layer that I can depend on. It is super soft when you first buy it but does get scratchier with wash and wear, even with gentle cycles, mild detergent, and hang drying. I tend to wear a thin, cotton free layer underneath for better comfort and more layers. While it does offer some stretch, it is very true to size, so if you are teetering between sizes, size up. You ’ ll be more comfortable and won ’ t risk circulation compression, which will ultimately make you more cold.

[ 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.

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.

[ 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!
