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 but could use some pockets
Special Size: 6" Inseam Contrast Trim without Pockets, Size: Small, Color: Navy/White
Obsessed with these shorts. They are so cute and comfy. They fit true to size and I love that there is a matching top you can buy separately. I feel like the material is pretty thick and I don't have to worry about it being see through. My only complaint is that there are no pockets.

Nice fabric
Special Size: 7" Inseam with Pockets, Size: X-Large, Color: Taupe
These are well made. The fabric is perfect! Not thin. I was disappointed that I ordered a size that was too large. I had to return. I need to get updated body measurements before reordering.
