Why We Like The Merino 150 Long-Sleeve Baselayer

It’s almost impossible not to get sweaty when you’re running from a pack of marmots that are hungry for your trail mix, but the Women’s Merino 150 Long-Sleeve Baselayer Top is just the ticket. Smartwool made it extra tough by combining its famous merino wool with a hint of synthetic, and wove the 150 with a flattering cut and seams that won’t cause discomfort when you’re sprinting away from 30 fat and not-so-cuddly alpine rodents.

Perfect for Early Spring Weather

Will Buy More For Sure

[This review was collected as part of a promotion.] Fits so well! #sweepstakes all I want is a full wardrobe of merino. Hesitant to try due to the price but so satisfied I've bought in 3 colors and w the matching legging baselayer. Realized I wasn't unhappy, just unhappy with my fabric. New merino shirt new life love it

I loved my first one so much I bought another one!

[This review was collected as part of a promotion.] This is the second shirt in this style that I have recently purchased. I loved the first one so much, I had to buy another one! Fits perfect, love the color, not scratchy at all, great for outdoor activities on cool spring days. #sweepstakes

Love the color (fuchsia)

[This review was collected as part of a promotion.] It's lighter weight which works great if the house is slightly chilly or under other layers if cold outside.

New style?

[This review was collected as part of a promotion.] I wear these all the time. However, I feel like the new ones are cut different. I have the same shirt from 2021 and it has a more fluid fit. What's nice about the old fit is it doesn't cling which is important in the hot Florida sun...yes, I wear my old smartwool shirt during the summer. Customer service suggested I purchase a size up if it felt too clingy, not sure yet. But I do wear the new clingier version during the winter.

Good base layer on the lightweight side

[This review was collected as part of a promotion.] Solid base layer - not for super cold days, but I can see using this on cool camping nights in summer. Perfect for shoulder seasons (for New England's climate).

Purchased for Arizona winters

[This review was collected as part of a promotion.] I just received these and our weather in Arizona is starting to warm up so I don't anticipate wearing this until next year. It is a nice light weight, fit is neither too tight or loose and the color is beautiful.

Great shirt from last year's line - great price!!

[This review was collected as part of a promotion.] Fits perfectly. I have an athletic build - 5'7", 130#, size medium. This shirt is super-long on me. I have a short torso (5/7" and have a 36" inseam). The shirt's hem hits below my glutes. By buying this shirt from last year's line, the color choices were limited (I chose black). The current version claims credit for some fit enhancements, but for the price I am happy with this shirt!
