REI Trail Running Shorts - Men'sis rated4.5714out of5by7.
Rated5out of5byfromPerfect...These shorts serve me for everyday walking around use, trail running, in the gym - super comfortable. They fit a little bigger than I had thought, however better a bit too big, than too small; I love the feel, length, comfort, pocket location (s)...Great purchase!!

Rated4out of5byfromGreat Running ShortsI would have given these five stars but the rubberized REI label on the inside of the waist band rubs me raw on a long run. The fit is great and true to other REI clothes I own. The material is light but rugged and the side pocket is perfect for my phone.

Rated4out of5byfromGreat shorts for everyday runningComfortable and nice looking shorts. I got the Navy pair and like the color as well. I appreciate the side pockets and back lumbar pocket for storing keys while I run.

Rated5out of5byfromMy Favorite Running ShortsI love these shorts. They are my #1 Choice for a long run. My key goes in the zipper pocket and my ipod nano and a jell shot goes in the other pocket. Personally I love that they don't have a liner because I don't like liners. I'd rather wear my own boxers and use them to prevent chaffing than a one size fits all liner. This will actually be my second pair of these shorts.

Rated4out of5byfromExcellent running shorts, good pocketsThese shorts are always at the top of my rotation for running. The overlapping center back double pocket is great. One zippered pocket for keys or some cash, and an open pocket for a gel or small mp3 player. The light stretchy fabric is great, and the length is a good middle ground. I would never run with anything in the cargo-type pocket on the leg, but it can hold a phone or something when you are walking around. I think having no liner is a plus. More versatile.
