Customer Reviews Smartwool Active Ultralite Short Sleeve

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!

I use this shirt for walking and hiking. It is cool, lightweight and comfortable.

I use this shirt when hiking and walking. It works great!

This shirt was amazing for a recent hot weather relay race. The sweat dried quickly and it provided just the right amount of coverage to prevent chafing and limited sun exposure. I'm not sure if it's rated for sun protection, but I didn't get burned in the sun. I wore it for 3 straight legs of my relay because it was so comfortable and felt so light and refreshing. I definitely want to order more in other colors. And it fit true to size. I ordered a large and I'm 5'6" around 175 pounds and it was perfect.

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.

Great fit!

I ride a bike and this top keeps me and doesn't stink when im done riding

Love the fit and feel of this shirt (I bought 2 and am really glad I did). On hot days the material is so light it almost feels like I'm not wearing a shirt. The length is great for biking but not too long for running.

Got this using a coupon from a Strava challenge and I'm so glad. It's comfortable - fits great and feels like it will be lightweight for summer. Love the color options too (I picked teal). #sweepstakes

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.

Lightweight, comfortable and so soft!

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

It's light, it shrinks a little bit in the dryer and the color is very vibrant. Feels so soft I love it. #sweepstakes

This lightweight, breathable and most comfortable T-shirt can be worn many different ways. I love its versatility. One can wear this shirt to work out, around the house, running errands or worn as a base layer. Its fit runs a bit big but ultimately is Insanely comfortable. This material is so soft next to your skin I never want to take it off. My favorite aspect of this shirt is its most flattering stitching along the sides of it. #SmartwoolLove

I like the fact that it is not slim cut like most women's tees these days. It is comfortable, very light and airy.

The shirt was comfortable and fit true to size. However it is so thin that you would need to wear a camisole underneath. Sadly has to be returned

The versatility of this shirt is beyond amazing. I can accomplish anything in this shirt, it fits me in all the right places and is probably the most comfortable shirt I own. #SmartwoolLove

I will wear this top all summer! The merino wool/tencel blend is very soft and lightweight which makes it perfect for warm days hiking or paddling. It is also very nice as a baselayer. It is not as fitted as other Smartwool tops, and the neck is a bit wide but these features aid in breathability. Looks like new after washing. The Hawaiian surf color is very pretty. #SmartwoolLove

This is one of the lightest shirts I have ever worn and it has made me incredibly excited for summer hiking season! I was impressed with how light the shirt felt without compromising on durability. It is still pretty cold up here in Alberta, Canada so I have mainly worn this shirt at the gym, while doing renos at home and underneath my winter jacket on the warmer days to walk my dog. This has definitely been my go-to gym shirt lately because it is very breathable and comfortable while I'm sweating it out on the bike. I cannot wait for summer hiking season because I can guarantee this will be the only shirt I want to wear while sweating it out on the uphill climbs (this means I will need to buy more in different colors :)). I have one small complaint about the shirt - I do find it to be more sheer than what I would normally buy (especially since I tend to wear dark leggings mostly), but didn't have any issues wearing a sports bra underneath! I highly recommend this piece for any of your high intensity activity and for lounging around the house (yes - it's that comfortable)! #SmartwoolLove

Another awesome product from Smartwool! I really enjoyed how light and soft this shirt was. When I went ice fishing, I wore this shirt as a base layer and love it! This would be a great gift for anyone that's hesitant on trying a wool shirt. I also love to wear this shirt just to lounge around the house in. The sizing threw me off for a bit. When I initially wore it, I honestly thought it was too big. However, after washing it I think the size of the shirt is good. No need to size down folks.

I absolutely love this shirt! It is a nice light weight shirt and a comfortable feel. I love how soft the material is! This shirt is perfect for warm days, those summer hiking trips and just even causal wear. I have the Hawaiian Surf Blue and I absolutely adore the color. It washes and dries great too! #SamrtWoolLove

This shirt is super soft and light! I can already tell that it is going to be absolutely PERFECT for summer hikes! The cut is really flattering, and the colour is really nice (I got aqua). Can't wait to be able to use it this summer :)

I really like the fell and confort of these shirts. They are good for intense exercise in hot weather where you want something light and cool. I use them for hiking. I do own several. The major drawback is that they start getting small holes after a while. Smartwool customer care was very helpful in replacing the ones where this happen. So I did get more.

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

extremely lightweight in a good way. i have black and the light blue, black hides bra lines better and helps the shirt look less like active wear and more like athleisure. I see more under the blue and it's a little more difficult to dress up.
