Excellent quality
Honestly the best gym apparel I've owned. Fit is true to size and the fabric holds up after dozens of washes.

Worth every dollar
Bought two more in different colours after the first one. Comfortable for lifting and running.

Great fit, slightly long
Love the cut and the colour is exactly as pictured. Length runs a touch long for me but otherwise perfect.

MN never disappoints
Quality is on par with my other MN Generation pieces. Shipping was fast and packaging was on point.
