Super happy with these shorts!!! Wore them on a full day at the theme park. Stayed in place and did not ride up. No pinching or constricting. The material is buttery soft and the blue is so vibrant and pretty!! Don’t show every bump and imperfection, but does show some. It’s not totally smoothing. Very work out friendly, heat friendly, running errands friendly. Would definitely recommend and plan to buy other colors. Comfy waist band as well.

Excellent Work-out & Biking Short

Special Size: 7" Inseam without Pockets, Size: Small, Color: Ocean Blue

I love these biker shorts. They have just the right amount of lycra and they are super soft. They are true to size, and they fit perfectly on my 5'2", 125-pound frame. I purchased them for use in bike riding, and I am very pleased with the fit and stretch. The inseam length is perfect for bike riding, and the legs don't ride up my thigh. The only con to all the pros is there isn't a phone pocket. I ride my bike around town, and I would have liked to have a pocket for my phone when going inside a store. These shorts are well worth the price. I purchased three different colors and love them all. I would definitely purchase this item again.

Cute and comfy and worth the price

Special Size: 5" Inseam with Pockets, Size: Small, Color: Flamingo Pink

These shorts are cute and comfy! I'm 5'5" and 120lbs and ordered a medium which fit perfectly, a small definitely would have been too tight. The high waist is flattering and the fabric is soft yet supportive. My only complaint is that the material isn't as thick as I would like. I love the 5″ inseam—it’s sporty without being too short. The pockets are convenient for keys or cards, and the material is opaque, breathable, and comfortable for everything from yoga to errands. A versatile, everyday essential which is worth it for the price. I’ll be buying in more colors!

Wanted to like them

Special Size: 6" Inseam Contrast Trim without Pockets, Size: Medium, Color: Flamingo Pink/White

These are very cute but no compression at all in the waist. Even if I was to size down I wouldn’t feel comfortable working out in them. They would be too loose. Maybe for leisure they’d be okay but for CrossFit or running or moving a lot, I wouldn’t bother.
