Smartwool  Merino Sport Ultralite T-Shirt - Women's

I was excited to see these shirts. The fiber combination is great and I have a bunch of heavier-weight smartwool shirts that I really like. I ordered one in serene blue and one in coral reef. As other reviewers noted, they are very sheer. Beyond bra visibility, I worry more about how much sun is getting through the fabric. Smartwool definitely nailed the cool summer weight of these shirts, but I don't want to have to put on sunscreen under my summer shirts. Their model photos definitely do not convey how sheer this fabric is.

This is my favorite of all my merino shirts. I tend to sweat a lot when I hike and it’s super breathable, dries quickly, and fights odor. It is slightly see through in bright lighting but with a sports bra, I don’t mind. (I have black) It’s a small sacrifice for the ultra thin fabric. I wish they made more colors, as I would order several more. I have the same shirt in the tank version and the long sleeve. The tank and short sleeve seem to run a tad large. I was able to wear a medium as they’re more fitted in the shoulders and have a slightly wider lower half. The long sleeve fits a little more like a base layer and I’ll need to send it back for a large.

First, this review is for the black shirt. It’s not see-thru :) I brought this shirt on a trip and wore it for a few hikes. It’s the perfect weight -allows breathability and resists odor. Dries fast. I wore it multiple times between washes and even to bed. It’s probably the most comfortable shirt I own- it’s soooo soft. I’m awkwardly between an M/L in smartwool and I sized up to a Large so I could tie the side. It’s adorable. Note on colors: I agree with the other reviews related to the shirt being see-thru for lighter colors, but the black is perfect.

[This review was collected as part of a promotion.] I love the Smartwool Ultralite shirts! I travel a great deal and these shirts are the best for any weather. They are super lightweight, repels odors (even with multiple wearing) and a great for layering. If you are on the fence about buying, don’t be. Try one and I guarantee you’ll be back for more.

This t-shirt is comfortable, breathes well, and is versatile to layer or wear by itself. The generous cut is welcome for us gals who aren't as athletically built. However, after two gentle launderings with garments of similar type and weight it developed several holes in the knit fabric. Chose to return to REI, not confident that attempting to mend would be successful.

I love Smartwool, I have several of their shirts, all in size medium. I love this shirt, it is very light and breezy and a great color, it would be perfect for running in hot weather... BUT, the medium I ordered is very big, it seems to be at least a size large, possibly an XL. I highly recommend this shirt, but size down at least one size. I am going to reorder in a smaller size.

I kept it because it was on sale but it’s very sheer and I’ll need to wear a tank top underneath it

This is a lovely, soft and very light shirt. It is true to size. However, it was quite sheer. (I bought the light green color.) I am not a person who likes to show off my bra while hiking. I returned it.

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.

This top will be perfect for backpacking. First the fabric is very soft against your skin and super comfortable. The size is perfect and looks great. It was very warm in my area today and it kept me cool at 70 degrees, looking forward to trying it at 90 degrees. I'm sure it will preform even better in hotter temps. I tested on how well it would pack down for backpacking. Fits in my small coffee cup with no issue and you feel no extra weight. The Hawaiian Surf color is really nice and flattering.
