Customer Reviews

Comments: I do agree with Grambol, Texas. From the top it appears as if you are wearing a skirt. However, they are great shorts. The liner is great, it is a little thicker and keeps my man bits warm in the winter but not hot in the summer. The waistband sometimes rolls up but it is not a big issue. Overall I am happy with the shorts.

Comments: I bought these shorts not knowing what to expect from them. I did, however, know that Pearl Izumi tends to make fantastic products. I decided to give them a shot. When I received them in the mail, I excitedly tried them on to see how they fit. To my surprise, they were quite roomy and wide. It looked as if I were wearing a skirt! Perhaps this is common with these types of shorts or would be with the narrowness of my waist (30 in), but it made me feel a little odd. I have short split shorts made by Brooks and Nike and they don't appear that way. Could there be a little too much material there? Maybe.
