Customer Reviews Smartwool Active Ultralite Short Sleeve

Since I just received it, I have only worn it once, shortly after we started running it poured with rain for 2 hours, so it stretched out a bit. But it preformed well and I like it.

This Smartwool Active Ultralite Short Sleeve is hands-down the most comfortable shirt I've ever worn. It's incredibly lightweight and breathable it legitimately feels like I'm almost not wearing a shirt at all. The fabric is so airy and soft against the skin, yet it wicks moisture perfectly and keeps me cool during any activity in the Phoenix heat. The merino properties are game-changing: anti-microbial so it stays fresh for multiple wears without needing a wash ideal for living in the hot Arizona desert where laundry piles up fast. It keeps you cool when you need it and warm when you need it, making it perfect for variable desert temps. I bought a size up just in case it would shrink (merino wool is known for that), but I've washed it multiple times exactly as the label says (cold wash, hang dry), and it hasn't shrunk, stretched, or lost its shape one bit holds up like a champ. I'm in the process of switching out all my shirts for merino wool ones like this for exactly those reasons. I snagged it on a random sale price, which made it a steal, but at full retail it's a bit steep for me right now, so I'll treasure this one and hopefully grab more when I can. If you're looking for a merino blend tee that disappears on your body while performing flawlessly, this is it. Highly recommend!

Superbe t-shirt for trail running

Great base layer for summer, or gym workouts, or even an undershirt under my suit and tie! Super comfy and lightweight

Great for working out

Perfect active shirt for gym and summer activities, perfect undershirt under my suit and tie at the office. Wish neckline/hole was a little tighter as it sags a little at end of day

Keep feet feeling fresh.

I've had this shirt for about a month and have used it for everything. I've used it as a comfortable sleep shirt, an undershirt for work, it has been great at the gym, and I've used it as a running base layer in 20 degrees (F) as well as on its own at 50 degrees. The fit is great, too. I find a lot of running shirts to be too slim (I have about a 41-42 cm chest); this shirt feels nice and loose while not looking baggy. I am currently using it for travel in Europe and am happy to report that I haven taken it on 3 runs and its only just now smelling like it needs a wash. Makes packing easy.

Great base layer for winter and summer sports. I've used it on the Peloton and on ski trips both in resort and off. The weight is very light but it still feels durable. I soaked it with sweat, let it air dry overnight and it didn't smell at all. Accidentally sent it through the dryer and it didn't really shrink. I'm 6'1" 175lbs and the medium is a good fit, not tight. Great product.

I wear this as an every day shirt. It's lightweight, but not see through. It keeps me warm when I need it here in the Wyoming winter. I love that it doesn't smell from multiple days of wear without a shower. I'm pretty curvy, so this accommodates my larger chest without rolling up in the back...or front...or side. Men's shirts are usually longer, more blocky, and more durable for cheaper and that's what I've found here. I will be taking it hiking and camping when that opportunity arises in warmer months.

I used the t shirt for a 6 day trek in Cambodia and it was amazing. Lightweight, breathes well and great for the extreme heat. It also dries very quickly, is super comfortable, of good quality and fits very well. I'm 6 ft , 165 lbs. I got a small.

Base layer for heat and workouts

Great for wearing as basic layer in a cold month of the year

Great outdoors shirt. Super soft and odor resistant. I like that it is thin but wears out quicker.

I wear this shirt as a base layer while I'm ski touring. It keeps me warm even if it is wet.

I love these shirts for running, even in hot humid weather they feel light. The material is very soft and smooth.

I bought two of these shirts a couple of years ago for hiking, and in the colder months used them as a base layer. Other brands of base layer shirts stink to high heaven as soon as you start to sweat but not these. They are really soft, super comfortable and dry quickly. I just bought two more because I basically wore the other two to death lol.

Great layer, no lingering odor, easy to rinse and quick to dry

Fantastically light and effortless to wear.

The Smartwool Men's Active Ultralite Short Sleeve is everything I want in a performance shirtsoft, breathable, and odor-resistant. It's lightweight yet durable, perfect for hiking, cycling, or everyday wear. The fit is athletic but comfortable, and it stays fresh far longer than synthetics. A go-to shirt for any adventure.

Super soft and comfortable for running. Absolutely no odor after my workout.

Nice fit, the dark color I got is not transparent.

Great piece for those warm summer days. Very comfortable.

Smartwool clothing is simply the best and now part of my everyday attire. Shirts, underwear and socks, all day and every day. Highly recommended!

Great shirt! Very comfortable.
