Reviews

Great shorts very supportive

"Great shorts very supportive. I was thinking I should probably get a size larger just because I read the size requirements and I’m glad I did because I’m athletic. I’m 5 foot nine and I weigh 147 pounds and the large fit be good."

— Sandra S. (5/5)

Biker shorts

"Love the fit, true to size. Material feels good and sturdy. Love they way they look."

— Debbie (5/5)

Love these for working out!

"I wear these for rollerblading and love that I can fit my phone and key fob in the pockets."

— Afton C. (5/5)

Long lasting

"The last time I bought these shorts was in 2018. I bought three pairs and the seam is just now loosening in one, and there’s a hole in the pocket of the other. Well worth the purchase, they last forever. Also, for any with a sensitive stomach, these are perfect. Any stomach compression gives me immediate, severe pain. These do not hurt in any way, and they stay up no matter the exercise. I’m talking GRIT, Pump, anything. I recommend this brand to everyone."

— Rachel K. (5/5)

Great Bike Shorts

"This is my 3rd pair of these shorts. They are very comfortable and fit well. This pair is slightly longer than my other pairs and the waist is different from previous years and is a bit stretchier, which i actually like. They don’t ride on when I wear them on my bike or the Peloton. They wear & wash very well. I always put them on low heat in the dryer and they do not shrink. I wear a size large in these shorts and wear a size 8."

— Elaine R. (5/5)

My go-to running shorts for years!

"Stay in place, pockets - perfect for running!"

Shorts

"Fits well; I would prefer a softer material, but it's fine. I will keep it. I like the side pockets"

— Laura G. (5/5)

My Go to Shorts

"This is my third time buying these shorts. They fit well and feel nice on. The only thing I would change is having them be a little longer but that’s just because I am tall. The pockets are deep enough for a large phone and keeps things contained. They are more of a swimsuit material and not so much that luxe fabric type. Still good quality and work well for sweaty workouts. They are squat proof too."

— Stefanie C. (5/5)
