[ Carthatt is a quality brand that is made affordable. I used this for my snow trip and it gave me warmth so I do n't have to layer too much. Very satisfied with my purchase!

Bobby
[ I knew I was getting a good shirt because this is my second one. It fits snug enough to keep out the wind. It wicks and dries like an athletic shirt. Since it is 100% polyester, it is likely more durable than most. It keeps its shape and looks better than most.

[ Best value for your money as far as base layers go. You can spend 3x more on Smartwool or Icebreaker if you are looking for the best with a hefty price tag. Overall, this lives up to Carhartt ’s name

Got this for my daughter, she is a teacher. Her room is cold and then she has bus duty periodically. So the 4. 0 is perfect for being somewhat sedentary. Surprisingly, actually keeps her warm!

Really warm underlayer. Used to ski on freezing temp and this plus good ski jacket was enough… even when it was snowing… The only thing is that it feels way different then the 2. 0 shirt. I also have one of that and the 3. 0 is more stiff and feels smaller. Specially in the neck and chest.

mrsguzzie
I purchased this Base Layer 3 shirt when I visited our local outlet store to place an order for another Under Armour shirt I liked. This shirt is thicker than a normal under layer shirt but is still comfortable if you wanted to wear additional layers. The cut of the shirt is super nice you might not want to hide it, though! It has thumb hole openings which are nice. I wore it alone several times since I bought it and was pleased at how well it kept me warm. I liked it so much I went to get a second one. They had sold out of the 3s but I snagged a 2 at least! My only negative comment would be it looks wrinkled when you remove it from the dryer. I only air dried it so maybe some heat might have gotten the wrinkles out. It's black so not that noticeable. Great shirt. I tried to get a 2nd one so obviously am happy with my purchase!

LeoK
[ I recently had the opportunity to try out the Smartwool Men's Classic Thermal Merino Base Layer 1/4 Zip, and I must say, it quickly became one of my favorite pieces of outdoor clothing. First and foremost, the quality of the merino wool used in this base layer is exceptional. The fabric is incredibly soft and comfortable against the skin, and it provides excellent insulation and warmth. I was impressed by how well it regulated my body temperature, keeping me warm in colder conditions and preventing overheating during more active pursuits. The natural moisture- wicking properties of merino wool also kept me dry and comfortable throughout my outdoor activities. The 1/4 zip design of this base layer is a great feature. It allows for easy ventilation and temperature control, especially during strenuous activities when you need to quickly release excess heat. The zipper is smooth and durable, and the collar provides added protection and warmth for the neck area. I found the fit of this base layer to be spot on. The slim yet stretchy design contours to the body without feeling restrictive, allowing for a full range of motion. The sleeves are the perfect length, and the shirt stays in place even during active movements. The overall construction feels solid, with flatlock seams that minimize chafing and enhance comfort. One of the standout features of this base layer is its odor resistance. Merino wool naturally has antimicrobial properties, meaning it inhibits the growth of odor- causing bacteria. Even after multiple days of use, the shirt remained fresh and odor- free, making it an excellent choice for multi- day hikes or backpacking trips when laundry facilities may be limited. Durability- wise, the Smartwool Men's Classic Thermal Merino Base Layer is impressive. The merino wool is robust and resistant to pilling, ensuring that the shirt maintains its quality and appearance even after repeated use and washes. I appreciated that it retained its shape and did n't stretch out over time. In terms of improvements, I would have liked to see a small zippered pocket or a media port for storing small essentials or routing headphone cables. This would have added convenience for those who like to listen to music or carry small items while on the move. Overall, the Smartwool Men's Classic Thermal Merino Base Layer 1/4 Zip exceeded my expectations in terms of comfort, performance, and durability. It is a versatile and reliable piece of outdoor clothing that provides excellent insulation, temperature regulation, and odor resistance. Whether you 're hiking, skiing, or engaging in any cold- weather activity, this base layer is a worthy investment that will keep you warm, dry, and comfortable throughout your adventures.

sof2024
[ This is my go- to base layer for skiing( or any other outdoor cardio activity... if I ever did one). It's form fitting and has great mobility. I always use merino fabric as my base layer since it's' breathable and odor- resistant. This top kept me warm but not overheated in 30 degree weather with a down ski jacket. I prefer to minimize my layers so this top paired with my jacket is all I need in everything but extremely cold or warm skiing weather. It's also stylish and looks good with ski pants on its own for apres!

[ I love smartwool classic( midweight) baselayers. Live in Ohio where it's freezing winters and these tops work great as a baselayer or a stand alone top. They are wool so they breathe and it dries quickly if it gets damp( Unlike cotton). I have multiple smartwool tops& love them all.

Jbear
[ Merino is THE stuff for active comfort in the cold. The key is staying dry between rain, snow, and sweat... it's challenging. 100%( 95 and 88 also good) merino helps to achieve this goal. It's warm when you need it to be and water( all types) evaporates quickly to keep you from getting chilled from damp clothing. It's got to be part of a system though, and you have to use that system properly or you will get damp and cold. We just came back from five nights in our tent@ an avg. of 26F at night. After hiking all day in these and then, putting on fresh Smartwool tops and bottoms we were warm all night( we could have stayed in the same set if we had to). Medium weight is probably fine for most applications, but do be sure you 've got the right system for the conditions. In summer and spring it's less critical, but in winter( THE best time IMO)... having the wrong gear can make for a miserable experience... and a dangerous one. Smartwool has the added benefit of being able to go in the dryer at home... not all merino products can. That's my take.

JKNOR
[ When it comes to staying warm during the winter, base layers are KEY! My old Smartwool long- sleeve lasted me years of use. Loved my first one so much that when it came to finally replace it, it was a no brainer. Kept me comfortable and warm during winter months of New Zealand, Japan, all the way to the summit of Mauna Kea. I 've never had a base layer fit so good right off the shelf. Felt like it I was putting on my favorite tshit. Could n't recommend it more

Duncanson1990
This shirt is fantastic. It ’s basically just a much needed upgrade version of the 1/2 zip elements. What I mean by that is the material is soft and comfortable and stretchy. The shirt also has a mesh ’s area running on the bottom of the arm that goes along the whole sleeve which is nice to help with cooling off. Also it seems to be lighter than the elements which helps it be a better choice to wear on warmer days. Hope these stick around and get more colors. I definitely recommend these especially if you were a fan of the 1/2 zip elements.

[ I ’ ve been averaging about 40 miles run a week this winter. This fleece top has been a game changer. It ’s incredibly warm and comfortable. I don ’ t have to wear so many layers anymore. I ’ m able to run with this and just another layer underneath. I ’ ve run in temperatures of almost 10° and still helped my body stay warm and I don ’ t feel any effects of the wind. Great top!

I 've tried several sun shirts of different brands and majority feel clammy and make me feel hot in the sun. Not this shirt! The material is thin, breathable and very soft on your skin. I actually prefer the quarter zip version over the MH hoody due to the bottom hem design( hoody has a draw string at the bottom which I do n't care for). This shirt also has better neck protection for me since I always wear a wide brim hat when I hike and I would n't use the hood. And I really appreciate having quarter zip to allow more air through. I 'd love to have more solid color options.

Absolutely love this product. I bought this for hiking as I 've had skin cancer. It is so light weight that I am now also wearing it when riding my mountain bike in the summer. I want 10 more! Please just make more colors. I also love the thumb hole as it keeps the sun off my hands when hiking.

[ Wonderful light fabric that feels nice and breathes well. Good for running but maybe not quite slim enough for cycling, billows a bit. I 'm 6' 5 '' and the large I bought fits very well except for the length. Looks fine but if I raise my arms the shirt rises over my natural belt line which I do n't love. A tall size would be nice, a larger size would be far to baggy for me.

This top is so comfortable. It is a nice space layer and keeps you warm. The color is an added bonus because it is a beautiful light purple. It has a lot of stretch and is great for walking and playing pickle ball. I am 5 ‘ 2 “ tall and weigh 100 pounds and I got them medium children ’s which fits perfect! Arms are just the right length which can be a problem for me in women ’s sizes. I loved it so much that I got two purple ones and one black one!

The Nike Swift Women's Dri- FIT UV 1/4- Zip Running Top offers everything you could want in activewear, and the colors are absolutely stunning! With vibrant options like volt, classic shades like brown, and bold hues like red, there ’s something for every mood and style. The breathable, sweat- wicking material ensures comfort, while the functional zipper allows adjustable ventilation. The watch window on the long sleeves is an incredibly thoughtful feature for fitness enthusiasts. With its UV protection and thumbholes for added practicality, this top combines smart design, performance, and style flawlessly.

[ The top exceeded my expectations greatly! It is extremely comfortable. I like how the sleeves have the hole for your watch. So smart! The shirt is very thin, therefore I thought I may be cold and need a jacket in cold weather, but it amazingly held my body heat in perfectly without making me hot. I would not change a thing about it. I am normally a medium but got this in a large since I thought I might layer underneath it, but it does not run large. A medium would have been fine. I will wear this for exercising outside, but it will also be a great base layer when snowboarding.

[ I always make sure to write reviews for items that work for me, just in case there ’s someone contemplating purchasing it. This tops is soft like butter and super comfortable to walk, run or run errands in. One of my favorite features is that it has a hole in the sleeve for you to have your watch out if you don ’ t want to sacrifice the thumb holes to do so. Very genius! I would love to purchase other colors and add to my collection. Great job on this one Nike!

We purchased this for my daughter to wear under her softball jersey to keep warm during cold spring games. She is a pitcher so she needed something that kept her warm but also was not constricting. This is exactly what we needed. My daughter said it was very comfortable and allowed her the freedom to move while playing softball. She also liked the neck line because she does n't like undershirts that are tight around the neck area.
