Customer Reviews Smartwool Active Ultralite Short Sleeve

Lightweight and comfortable. Longer than I hoped but expect will shrink.

I used it on an overnight adventure, my only minor complaint was the external stitching for the side seam started to fray under the pressure of the pack. It worked great for day hiking/running!

This is the one and only shirt you need. I bought it in black, and it's my newest favorite. Fabric is light, dries in a second, and is super thin but not see thru. The only downside is the shoulders are a bit awkward shaped since they're raglan, like there's too much space in the shoulder area (maybe it's based on the men's pattern?) but it's not weird enough to really be noticeable. As usual, when I get a new smartwool item, I wear it for a couple days to test how stink-proof it is. Well I got to day 3 before I dribbled cheese sauce down the front, and had to wash it. You should get this shirt if: you're traveling and don't have easy laundry access, you don't like doing laundry (me!) or you just want to look and feel good in any weather.

This shirt is so comfortable I wore it 3 days straight and no stink. Iwanted to test it oit and it lives up to its word. It's thin enoughto be comfortable in all summer but not see through. So soft and it keeps its shape even after a couple days. I plan on using this for my long distance thru hike inthe sierras but i alsowear this to work. It's perfect for any acticvity any day. Nice loose fit but not too loose, its flattering for my imperfect body type.

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.

Fantastic shirt for hiking and running! Thin, moisture wicking,, super comfortable!

I got the blue color, very pretty. The material is very soft and feels great against your skin. It is very light weight which I need for hiking trip and it drys quickly. My only disappointment is that it didn't resist getting stinky as much as I thought wool should. It could be because this is blended with tencel.

Have worn this a few times. Very comfortable. The size was a little on the big side which allowed me to layer it with a long sleeve shirt. Kept my core plenty warm that way. #smartwoollove

The material is so light and soft. It'll be perfect for summer hikes, camping, working out and even running errands. My only recommendation is to get one size smaller #smartwoollove

Didn't fit right, wasn't crazy about the material

Loved everything about this shirt except that it was see-through. It went back.

The description is accurate of this shirt.

I'm not sure how the manufacturer could do this, but it would be nice if it could be less see through while still being ultra light. It's will be a nice pre-season first layer. I am mostly excited for summertime wear in this one.

The fabric is light and a great wool for summer, but the fit is not for me. I opted for XL and it is pretty straight up-and-down. Pulls across the chest, pulling fabric from the armpits, while bagging in the back and waist. Too boxy for my shape.

I love the idea but this shirt is so thin it's almost see through. The waistband of a darker bottom could easily be seen. Not sure it works for me.

This shirt is a great layering piece to have while hiking, biking, or just hanging around the house. Im not sure that I would wear it on its own as it is pretty see through in the orange/pink plant based dye. #smartwoollove

I love merino wool clothing, but this top was too see-through. I couldn't wear it without another layer on top, so unfortunately I had to return it.

I wore this shirt on a five-mile hike in June in West Virginia, and it left me feeling overheated and sweaty. I understand that it's a merino blend, but I was expecting more of the benefits of merino, which I feel were lacking. I've initiated a return claim with Smartwool, and hope I'm able to return it. On the plus side, Deep Lake is a beautiful color, and the shirt drapes nicely!

This item is basically disposable. Two holes in the sleeve after the first wear. Likely a flaw in the fabric. Beware the return policy. You need to pay for the item to be returned to Montreal.

Comfortable tshirt but it did not last a season. Has holes starting in it already. Disappointing and not up to Smartwool's usual standard.

I love the shirt but developed two small holes after 1 wear and wash per laundry instructions. I sent my info to customer service on April 13,2022 and again on April 25, 2022 but have yet to get a reply!

Way too big!! I always buy Smartwool clothing in xs and it fits great. This however is Huge!! Had to return it.

sixing is all wrong. I have always been a small and found I now need xtra small
