Perfect base layer for Spring in the mountains. Not too light, not too heavy, just right.

Super comfortable first wear while on a 2 day backpacking trip. It made a great base layer and then when temps when up it was nice on its own. And a layer of sun protection with long sleeves! Odor control was evident, but control being the key word--definitely not absent. I recommend this shirt and look forward to using again on the next hike and for my trip to the Tetons next month (as well as trying as a base layer for snow skiing!).

Like most Smartwool products I have purchased, this one is a nice weight, completely soft and comfortable AND attractive. I get compliments on it all the time.

Bought for a hiking baselayer. Expensive but I think its worth it. More comfy in the cold than a synthetic baselayer. Not a compression shirt. I use under a fleece. Doesn't smell after a full day of hiking.

This is my second purchase of a Smartwool Men's Classic All-Season Merino LS Base Layer - this is a great lighter weight item that breathes well but is warm enough when it gets cooler.

Fits well and well adapted design as a base layer. I have not worn it on hikes but I believe it will perform beyond my expectations in that setting

I own several Smartwool tops but this is one of my favorites. The slightly heavier material is ideal for stand alone yet still layers nicely. Never bulky. Quality is what you would expect from Smartwool. Excellent.

I have tried more than one brand of merino tops Keep coming back to smart wool for best quality and fit. They also keep their shape. The price is inline with other brands

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.
