Suuuper breathable, comfortable, thoughtfully made
This shirt is great! The material was so breathable I literally felt topless *nervous laughter*. It’s also very quick dry. I work as an aquarist, so I am constantly getting wet at work and this shirt dries fast, even in winter. It preforms really great for running -nothing rubbed at all. The seams are very thoughtfully designed and stitched. The neck line is higher than my usual style (I like the modest look for running, actually!) and I thought it might rub my neck, but the fabric is so light and comfortable I didn’t notice it at all! The high neckline would also mean less sun exposure during the spring and summer, which is nice. Very comfortable cut and fabric! I never wear orange but I actually like this color and think it looks pretty good on me. There are a little reflectors on the sleeve and hip, but somehow they too are soft. I am 5” 5’ and about 160 lbs with an athletic (square?) build (35 in. waist, 40 in. bust) and the Medium size fit perfectly. I was afraid the sleeves would be too small but they were perfect. It got staticky easily (you can see in the photo) but that was probably my fault for not using a dryer sheet. By the way, it says “line dry” on the inside (no tags! another nice, no-rub touch!) and I definitely accidentally put it in the dryer on high BUT the fabric is fine -nothing bad happened! Overall great shirt! VERY VERY breathable and comfortable! Good for running and outdoor activity use. I’m going to wear it backpacking on the Trans-Catalina Trail (40mi) next!
Breathable, comfortable, and cute!
This shirt is going to be my new favorite for the trail this summer. The shirt is very breathable, moisture wicking, quick drying, and I like color! Unfortunately I was not able to use it out in the wild yet, due to it being 19° where I live. The shirt is not rated for cold-weather, and is designed as a spring or summer wear shirt. I did however wear it to the gym, work, and around the house. I like that the shirt is slightly longer in the back and pleated on the sides. I also love that the shirt is not see-through! I have a black bra on in these pictures and you can’t even tell! I love that REI makes clothes for plus size women. I am wearing a size 1X in this photo and it fit perfect. My only complaint is that I wish it was a little more form fitting as it’s very loose in the stomach area, but I’m sure I’ll appreciate that on the trail backpacking this spring. I am 5’7”, 225lbs, and a 42DD. I would definitely recommend this shirt to others and I may even buy a few more in other colors for myself.
Great for a run and on the trails
This shirt is hella comfy, lightweight, dries quickly. The fit is loose, which I prefer being a bigger woman. I wore it on a trail jog and twice on a hike and it did not disappoint with how quickly it dried and it is so lightweight it doesn't feel like you are wearing anything. There is breathability and softness. The sleeves aren't too short like some woman's shirts can be and there's some coverage on the backside, which I appreciate. The only reason I gave it 4 stars instead of 5 is because I don't really like the color. I'd prefer something darker like a forest green or red wine BUT that was my only con that I ran into.
Great Lightweight Wicking Blouse!
Excellent lightweight wicking blouse, and the best thing about it is, it feels like you're wearing nothing, even when layered up. I hiked and biked in this blouse, and since it's still chilly around here, I layered up, and didn't work up a mid-summer, high heat sweat, but it wicked well in the conditions I used it in, and based on my experience with other wicking blouses major brand blouses, expect this one to do the same. The feel of the material is softer and more natural feeling than some other major brands I've used. It also does well against the stink factor if you have to wear it a few days without washing. It is washer-machine friendly, but I hand washed it, hand squeezed it dry (but didn't wring it, so it was wetter than it might have been otherwise), hung it up in chilly weather, and it dried in a reasonable amount of time given the weather. I think it would dry quickly in hot weather. I also really like the long cut of it in the back. Great blouse. A few of these are going to be in my closet.
Love the material, medium weight but dry feel
The material on this shirt is great. It has a nice medium weight, it's not see-through, and it pulls moisture very well, without being too hot. It's also quick drying. After a medium intensity run, with a decent amount of sweating, there were no embarrassing dark wet spots. Also, the fabric did not feel sweaty, which was great. If you get very heavy sweat, you may get some darkening, but comparatively it's very good. The fabric does show darker when drenched. I accidentally soaked it while turning on the shower. It took about two and a half hours to dry from saturation. The cut of the shirt is almost perfect, but it didn't fit perfectly for this curvy lady. I would describe the cut as relaxed fitted. I am 5'7 and a 38D, XL with a long torso. I had some minor fabric pulling at the side of my chest, though not so much I wouldn't wear it on the trail. I am guessing the shirt would be a great fit for a 38C, or 34D and below. The bright peach color will be nice for the summer sun, and it's a distinct enough orange I'd feel safe wearing it as a safety orange alternative in the woods during deer season. Overall I'm very pleased with this shirt.
Great fabric!
I received this free product in exchange for an honest review. First things first, I like technical fabrics made for athletics/working out etc. but I don’t like them to feel slick or sticky or hot like some manmade fabrics can. The fabric for this shirt is amazingly comfortable. The air goes right through it but yet it still feels substantial (like it can withstand more than a season of use). I appreciate that there is some reinforcing on the back of the crew neck. Speaking of crew neck, I like a good crew neck as opposed to a “V” or scoop neck for both sun protection and protection from my pack or running vest straps. This shirt has a pretty good crew. I like the raglan sleeves but I find them just a little short for my liking. I have broadish shoulders and often have problems with sleeves and shoulder seams. Because of this, I usually go a size up with the hopes of correcting that problem – in this shirt I went up a size as well but I still think the sleeves are a little short. I understand this is 100% a personal preference thing so take it for what it is. Lastly, I always do a wash test for sports shirts because I like to backpack and need a shirt that can dry quickly and resist stank. This is not that shirt. Washed in the dryer and hung to dry, it’s fine. Hand-rinsed in the shower (because never use soap in the backcountry) and hung outside to dry, it didn’t fare as well. It took a while to dry and maintained the stank. This is not a deal killer, just something to have in mind if you intend to use on a multi-day backcountry trek. Overall, I really love the fabric and the shirt has been great so far.
Wicking, super soft, relaxed fit
This shirt is incredibly soft and lightweight, great for running or being active in general. A relaxed fit and a relatively high and narrow neck, combined with a little extra length in the back, provide coverage I appreciate. Additionally, this shirt wicks moisture very effectively – I hardly noticed I was sweaty after workouts, even though the back and underarms of the shirt were thoroughly wet. The material takes a little longer to dry than I anticipated (about 3 hours in a dry Michigan home in February), but it washes well without pilling or stretching. I would love a little resistance to odor: the BO smell comes out fine in the wash, but hangs around until then. This isn’t the shirt I will be wearing if I need to run errands after being in the gym. All-in-all an incredibly comfortable shirt that wicks extremely well.
Excellent fabric, poor neckline
The material is fantastic as it’s light as my On performance shirt. What I don’t like about this shirt, as another reviewer also mentioned, is the neckline. I find myself pulling down the neckline of shirt periodically when I’m the treadmill at an incline walk or run. I’ve had to stop at check my shirt to see if I’m wearing it backwards by chance many times. For this reason, sadly the shirts have to go back. I want perfection from my workout shirts. Bummer bc I have the matching shorts with each shirt. Perhaps the tank will work better with it’s deeper neckline. And yes, it does run small. So Size up if you’re thinking of buying this.
Super lightweight and comfortable
I have had lots of exercise gear shirts over the years, but this will be my new go-to favorite shirt to run or exercise in. It's super lightweight, kind of an unusual fabric, but super comfortable. It's not like other fabrics, it's lighter, better, breathable. I've been using this for my indoor workouts since it's winter, but I look forward to running in it in steamier temps. Seems like a great shirt for wicking on a hot day. It fits well and the sleeve length provides good coverage (not too little, not too much). I also have a longer torso, and it's long enough to provide good coverage in the back. Great shirt! I definitely want another one.
A great option
I was pleasantly surprised by this shirt. The neckline is more unisex than I initially thought it would be (which I prefer in my clothing) and the dry fit was comfortable and not itchy like some can be. The color is too girly for my taste (the minty green color) but had it been available in a more neutral color it would definitely become a regular in my rotation. It was too cold to test this item outside so I ran in it on the treadmill and found it comfortable. It washed well with no shrinkage, pulling or pilling of the fabric. I received this one in exchange for a review, but may have to purchase another color for summer hiking.
