Customer Reviews Smartwool Active Ultralite Short Sleeve

Shirts look great but not very breathable when exercising. They will be soaked after a normal run.

Love this versatile tee! Cool and comfy for the summer!

In warm weather, not even really hot, I sweat through this shirt and it's like wearing a wet piece of gauze. The regular weight seems to hold up better and wick sweat, but this is just sopping wet at the slightest effort. Only works well as a a little extra core layer for skiing or winter sports.

It's a bigger fitting shirt than the regular shirt with longer sleeves. I wear a 46 jacket size and these are an athletic fit (slim but not chub shaming).

Most comfortable tee I've ever owned. Plan on buying more.

Played a round of golf yesterday in 87 degree heat and 80%+ humidity. The Ultralite lived up to its name! Kept me cool and remarkably dry for the full 18 holes.

I use this for everyday. Not for exercising too much. Great base layer for spring weather, and when spring wants to come but it gets cold all of a sudden. Have yet to use in summer weather. I wish it wasn't so thin, but for this kind of product, it's the nature of the beast. Just gotta be careful when taking care of it, and make sure not to run through thorny bushes with it...

great merino blend shirt...lightweight. the seams are in the right place and don't hinder movement. The tag was LARGE, so it was cutoff immediately. Thankfully the washing instructions were straight forward and not any different than other clothing I own

I wore these in the hottest days of the year in WI. They performed very very well in terms of breathability

Soft and good looking shirt. Love it.

Very, very light and comfortable. Not probably the best running shirt in high heat and humidity, but perfect otherwise. Will cling to you with any sweat -

Great for running but a little delicate.

Great fit and feel but a little delicate. I'd buy again but take good care of it. Definitely wouldn't play rugby in it.

Great material but the neck opening is too large which makes the shirt look sloppy. #sweepstakes

The material is awesome for running, but the neck opening is too large. I makes the shirt look sloppy.

I ordered 5 of these shirts and love the look and the comfort. I walk dogs throughout the day and, with the heat, I do break a sweat. I like that these shirts don't smell after I sweat.

The description says "body-hugging athletic fit". That's accurate for other Smartwool shirts I've purchased, including the early ultra lightweight shirts I got from Smartwool between 2017-2019. These ultralite shirts have a very different fit: they billow out between the armpit and waist, and hang loosely over most of the body. It would be "body-hugging" if I had an oversize stomach perhaps. Terrible.

Wore this shirt for a 5 day backpacking trip in the Smokey Mountains. Dried quickly in humid conditions. Negative is mice loved it. Ate multiple holes drying at night.

Great shirt. Fits well, looks good, simple.

I really like the color and the feel of the fabric. It is well made and comfortable to wear. I wear to run on warm days and it dries quickly and keeps odor at bay. My only complaint is the fabric is thin enough that it is a little bit see through.

stylish and great tailoring. nice color, fits the need for a great looking piece of clothing. suitable for all occasions, formal and informal. would definitely consider purchasing addiotna; colors

I wore these when I hiked across Spain on the Camino de Santiago. This was 4 years ago and I now wear them when playing court sports in the Sonora desert think HOT! On the 550 mile hike I did hand laundry every day and they're great because they dry quickly. Of course wicking perspiration and no body odor I s also great. They still look good and have no snags or that other merino tee shirt brands have done for me. I just bought 3 more, 2 of which are the super light fabric. It's nice that Smartwool came out with new colors too.
