5
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.

This compression shirt is a staple for me. In the past I had always struggled with my elbow pads slipping mid- game and have even had injuries related to the problem.

Little Tip: if in between sizes I would recommend sizing up as I did. Thanks Shock Doctor!

[ 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.

Thunderbolt417
[ 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.

JG
[ The Merino Tech Lite II Short Sleeve T- Shirt is hands down one of the best t- shirts I 've owned. It's lightweight, soft, and super versatile, making it perfect for everything from hiking to casual wear. Why I Love It: ✔ Soft& Comfortable- No itch, just smooth merino that feels great against the skin. ✔ Breathable& Moisture- Wicking- Stays cool in warm weather and dries quickly. ✔ Odor- Resistant- Worn it multiple times between washes, and it still smells fresh. ✔ Great Fit& Versatility- Works well as a standalone tee or a base layer. A Couple of Considerations: ⚠ Fabric is lightweight, so be mindful of snags. ⚠ A bit pricey, but the quality and durability make it worth it. If you 're looking for a high- quality merino t- shirt that's comfortable, breathable, and perfect for any occasion, this one's a winner. I 'll definitely be buying more!

Dee
[ Just reviewed the long sleeve base layer, and like both of these tops. Since it is still winter in Colorado, I have been wearing the short sleeve T- shirt on the 65 degree days we sometimes have. I also like to wear the men's as opposed to the ladies for the looser fit.

[ 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.

For me the fold back sleeves make it a definite keeper. They not only keep your elbow pads from sliding, they go over the straps and keep them from detaching from the velcro when I put my jersey on. It ’s the little things that make me a happy hockey player.

I bought one of these, and then a second, and then a third and fourth. I run a farm and wear this top almost exclusively. It ’s light and breezy in the hot humid summer, and I can put it through lots of activities and it stands up to them all. It maintains color and shape after many wears and washes. I prefer loose tops: I ’ m a size 6, 34D, and I got a medium. Couldn ’ t be happier with this top!

[ 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

I purchased this top( and the leggings together as a set). Altogether, it is one of the better base layer fits I ’ ve had the chance to try out in the elements. Overall the top is probably my favorite piece, not only because of the high quality materials used- but because of the sleeve length. As a tall/lanky girly, some genuine long sleeves are always greatly appreciated. The style is also a great plus, the outfit goes with pretty well everything( purchased in black for this reason). The outfit looks great together, but they can also be interchanged with other pieces and they still look awesome all while keeping you warm:)
