[ 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.

My daughter used this a few times this fall during some cold weather softball tournaments. She said it kept her warm. Wasn ’ t restricting during pitching or batting.

You don ’ t realize how much you need a heated base layer until you have one! It ’s been such a benefit to various aspects of my life. I wear it beneath my layers when spending time outdoors during winter in Wisconsin. But I ’ ve also worn it to work( in an office) during especially cold days. It fits true to size and is comfy. Somehow it seems to trap heat inside yet it ’s also breathable, I don ’ t sweat in it like I have with other base layers.
5
The Base Layer Shirt takes the bite out of any cold day! And the battery last for hours! Washed it in a cold wash then hung it to dry, easy peesey! Definitely worth it!

Definitely worth having extra battery banks if you ’ re skiing all day or anything like that, also could use an extra hole in the battery pouch so you can route the cable to a pant pocket more easily. Besides that, it definitely lasts through the wash and multiple winters

[ 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.

[ 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

[ If you ’ re even thinking of going up to the mountains to ski or snowboard for a few days you better have all the layers for any conditions.

The button is very helpful too being right below the neck area. This shirt works while working or just hanging out!

[ 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.

[ I 've long been an unabashed devotee of all Smartwool products but their base layers, like the classic all- season merino long sleeve shirt, is truly the best money can buy. Since my days of living in the frigid mountains of northern Utah, I 've discovered the breathability of Smartwool's all- season merino long sleeve base layer makes it both the perfect shirt for keeping warm on winter's coldest days as well as ideal workout apparel. Smartwool base layers also make the best all- season pajamas imaginable. The all- season merino long sleeve shirt feels like a gentle hug when you slip it on, and remains comfortable until you 've completed your workout — whether it be a 3- mile hike in the frigid cold or a home gym weight training session. Smartwool has long been the gold standard for merino wool apparel. When you purchase your first Smartwool product, you 'll understand why.
