Customer Reviews Smartwool Active Ultralite Short Sleeve

Love how comfortable this Summer shirts are. They do run about 2 sizes bigger, wear medium but on these I ordered them x-small and they fit perfectly- loose fit.

I've worn this for a trail run in NorCal in 80 weather and as a base layer on a beach hike. The shirt performed well in both applications. It is comfortable, no chafing and dries reasonably quickly. Low odor as expected. Fit is great. Small fits me a tiny bit loosely at 5'4" 120. You could go XS if you don't have a menopause belly. I've washed it and it does have some wrinkles, but should hold up well without pilling. I chose the slightly darker colors because it is thin and a dark sports bra will show through.

Wonderful shirt for hiking. Small fits close.. medium is baggy (5'6" 130lb). Excellent wicking and odor control. Dries in a flash, on out of your body.

Great fit. Light soft feel. Too thin to be worn without a sports bra

This shirt is lightweight, comfortable, and has all the great benefits of wool. As the other reviewers have said it runs a bit big. I normally wear between a L and XL in Smartwool t-shirts so I ordered a large and it's a bit big. It's been great for hiking and look forward to using it kayaking in the summer.

The fit is great and the fabric is comfortable. The fabric is very thin, so my skin shows through the fabric. Most people would probably be okay with this.

Based on the product description, I sized down and it is still nice and roomy. I typically buy the regular short-sleeve tees for hiking so I won't get smelly, and because they are fitted, I usually size up, but my regular size is still roomy in this style. I bought this shirt for travel, and in the Hawaiian Surf color I do not think it is see-through. Lucky that this is the color I've been craving! I prefer less muted colors. The slightly wider neckline is very flattering and not so wide that regular bra straps would show. I've just come back from a southern hemisphere trip in warm weather, and only took one Smartwool tee that I used for long walks. It never got smelly. My regular travel shirts did, and so when I saw this great color online, I got my husband to order it for me in case my size and color were sold out before I got home. I have my new favorite shirt.

This was my first time wearing an ultra lite piece and I can already see it becoming a staple for summer. I run hot and sweat at the drop of the hat, so love how light and soft this shirt is! When I sweat this much in synthetic materials I find I smell terrible within the first half hour of hiking. In this shirt I don't! Not only that, but I have worn it 4 times already and I still have not needed to wash it - if it's sweaty, I just hang it to dry out (which doesn't take long given how light it is) and it doesn't smell once dry! I love the see-through ness of it also, the colour (bleached aqua) is pretty and looks great with a dark blue/green sports bra underneath. I like my t-shirts to fit loose, so I usually order a large in regular t-shirts - however, the fit of this one is so light and loose I think a size medium would have been a better fit while still being loose and comfortable. So bottom line - super soft, comfy, packable!

I've purchased 2 of these shirts and have had problems with them getting holes without hardly any use. Both were laundered per the instructions. Not sure what it is, but I keep ordering them because I like the lightweight material. I wasn't able to find the right size on the last one, and sized down to XS, but that didn't work. Customer service has been great at replacing the shirts that got holes.

I was looking for a tshirt like one Smartwool doesn't make anymore. This one would be great for exercise but I wanted something thicker to use for everyday use. Bring back the Merino Sport 150!!

I love this shirt! It is soft & comfortable! The fit is great and flattering! It is perfect for hiking! I will be getting in more colors!

I have been buying these for her for a decade and she just loves them to death. Skiing, cycling, hiking, they are a key laying piece for her.

Perfect casual tshirt very breathable and comfortable. Usually tshirts bother me with tight armpits but this one fits well. Would love to see even more colors. .

This shirt is great for so many things - travel, hiking, every day wear, etc. The wool is very comfortable and soft while still providing all of the same benefits like odor control. Great, versatile shirt to include in your wardrobe.

I've been wearing this t shirt for running and it has held up to the advertising, it wicks away sweat and does not smell, other than a "wool" odor which is not unpleasant. It's a very soft, not scratchy at all, fabric; and it's a comfortable fit. Yes, I will order from Smartwool again!!

Used for packing light when I travel. Like an easy fit so need XL not L, at 152 lbs & 5'4" I want to see/buy true navy, orange, yellow & bright, clear, leaf green, not medium colours like teal, peach & army green. I like the black.

I recently went on Safari in Africa, and whether went from blistering hot to windy and cold I wore this I wore this T-shirt for both. During the heat, it wasn't too hot or suffocating during the cold. I threw on my wool sweatshirt and I was warmer than everyone else who is bundled up in blankets.

I now have three of these T-shirts and I wear them for hiking, gardening, and just plain casual wear. I love that they are lightweight and ideal for the very hot weather we've had this summer. They don't get a bad odor when I perspire! I do have to be careful when I wear them for gardening as one of them has snagged fairly easily. So I avoid wearing it when I'll be in the raspberries! The material is rather thin so I wouldn't wear it with a printed bra underneath.

I now have three of these crew neck versions ultra lite tops and love them. Great for everyday, and wonderful for backpacking! Highly recommend. I can be in between a small and medium, wear a small in this shirt and they have been consistently sized though ordered at different times/ years

So light as a layer and, for traveling, easy to rinse out and quick to dry!

Got the black for travel. Love the weight.

Doing the TMB and this shirt is great. It's keeping me cool. It is very thin but I've been berating it under a Su shirt. Great length and fits true to size, very lightweight, and keeps me from being too stinky!

This shirt is great for travel and hiking. It's lightweight and since it's wool, it's odor resistant. Love! I had 3 and bought two more.

Light weight-like going naked!!

Amazing! I love these shirts. I already had three and just ordered two more.
