Customer Reviews

Comments: These shorts are not much at all like the previous Brooks Infiniti shorts. I used to always reach for the Brooks because of how good they felt. The material was lightweight and the shorts never got in the way. The new shorts are made of a different material - which may dry faster - but the shorts don't give quite like the older model did. If you are squatting or climbing hills, you can feel the material pull tight against your read end. This is something I don't much like. The combination of the new material and the change in the split design just makes for a split short that doesn't fit as well as the older model.
