Lightweight Running Crop Top
I wore this shirt on an outdoor run on a warmer day and it was very comfortable. It's is lightweight and breathable. It is a little shorter on my frame than ideal for a crop top, but fine if I am wearing higher waisted leggings. I also wore it as my airport attire for a full travel day and it was very comfortable and made it so I wasn't sweating rushing to make my connections.
Cropped running shirt
Running shirt that is light and airy. The fabric is stretchy with reflective material on the front and back. The shirt feels great. However, I didn't like the cropped length of the shirt. It would have been five stars if it was a couple inches longer and less boxy.
Cute, comfortable, and easy to wear
This shirt is incredibly effortless to work out in! It’s very comfortable, kept me from getting too warm, and looks really cute while you’re at it. The cropped length is trendy, the color is great for spring, and I’m looking forward to wearing it over and over again. it seems to wrinkle a little bit easily, so if you’re packing it make sure to take some care. Overall, it seems like the high-quality type of product I would expect from REI.
Nice for hot weather but unsure about fit/style
Love the light, quick-dry fabric, but it runs quite large (I received an XS and normally am closer to an M) and the style is a bit boxy for my taste/body shape. That being said, the loose fit does make it quite comfortable, especially for runs and hikes on hot days. I received this for free as part of the REI Trailblazers program in exchange for my honest review
Run Shirt
I used it while working out and running and walking on the treadmill. The material is soft, lightweight, comfortable, and easy to wash. Dries quickly. I would prefer it to be a little longer in length for me. Plenty of room in the arm and shoulder area.
Nice material
I liked the material and the roominess for exercise. While i don't mind the crop it rode up and exposed more than i liked. I think it would have been better with a larger size. I had a friend try it on and it worked well for her. Torso differences.
Love it! Want other colors!
Absolutely love this! Light fabric that wicks really well! It is generously shaped but not boxy. I have worn it around the house as well as to the gym and it’s been great. It pairs so well with my high waisted leggings
LOVE IT!
Im obsessed with this top! The crop length and box style is perfect for my frame. I appreciate how it’s just a little bit longer in the back. When I tried it on, I immediately noticed how cooling it felt. I also like added stitching and the stylized reflective pieces. I just wish there were more colors!
