Customer Reviews Smartwool Merino 150 Base Layer 1/4 Zip

I use it on top of a t-shirt to go to work and also on top a base-layer to go for runs. Great for work outs and great to go to the office

It was a Christmas present for my son, who loves it and wears it often. He is 6'1 and weighs about 165lbs, the medium fits him perfectly and the arms are long enough.

need bigger size

I now have four of these shirts. Very comfy and versatile.

I wear Smartwool when I backpack and dayhike. I use different weight baselayers depending on the temperature. I like Smartwool because they are warm and dry quickly.

I use it for hiking when the temperature hits around 50 degrees. I prefer shirts that are a little baggy so the extra large is a perfect size for me. Extremely comfortable, breathable and holds its shape thru repeated washings. Well made! Perfect length! I would buy again but maybe a darker color next time. This is a quality shirt!

Fits perfect and keeps me warm

Great quality base layer.

I use it as a light base layer that is not too heavy for indoors. I really love it. Soft and well made. Feels light but tough and durable.

This is my go-to shirt to wear for all activities...especially road trips! Driving from Northern MN to Florida has a variety of temperature changes, but wearing this allows me to have a comfortable ride the entire time! #sweepstakes 6'1", 190lbs size Large fits wonderfully.

If you could take just one shirt on a three-season backpacking trip, this is it. I know, I have. I bought my first one back in 2017 when I decided to take a chance on an even lighter-weight long sleeve top for warmer weather camping instead of the 250 top I used (and still do) . I figured that the long sleeves would be good for sun protection and the wool fabric would give me wide temperature performance, from the cool evening temps to fairly warm daytime temps (common where I backpack in the Western US). Indeed, after over a dozen backpacking trips since 2016, including a 12 day trip to Philmont, NM in which I basically wore the 150 the entire time, this shirt stands up to the rigors of active backcountry use. It provides just enough warmth during cooler temps, enough breathability during strenuous efforts, and none of odor issues associated with wearing synthetic fabrics over multiple days. Sadly, my original shirt, in a fine textured gray, got a bit chewed out last year by some aggressive blackberry branches during a service project, so there are now some tiny holes in the chest area. Though I've bought two new shirts to take its place, I keep wearing my old shirt despite my wife's protests. My only complaint...the fabric is too thin to protect against mosquitoes (learned this the hard way during a Colorado backpacking trip), so you'll need to cover up with another layer, or spray permethrin on the shirt. Smartwool staff: Please continue to make high-quality, durable clothing like this top. I know that this top is not cheap, but when you're in the backcountry, good equipment is much more essential than saving a couple of dollars.

Excellent quality and perfect fit.

Got this for my dad and he loves it. #sweepstakes

My brother lives in western Washington where it is cold and damp all winter. This was a Christmas gift for him. He loves it and says that it really helps to keep him warm. He is grateful that it is washable and can go in the dryer. My husband has several of your undershirts, so we know the quality is good. Thanks her helping my brother stay warm.

Sweater indoors Base layer before going outside in cold

It's a Christmas gift for my son. I think he will love it! Perfect weight for layering or just a cool night! Excited for him to open it!

Love love love

Soft-textured Merino wool, form-fitting, nice styling

Very nice but lighter weight than expected so have returned it. Will stick with the original 250 going forward.

Overpriced when compared to similar apparel.

Pretty thin. Thought I was getting more thickness.
