Rated 5 out of 5 by Stryder Best shorts I own!
I have two pairs now and would get more if more colors came out. It fits perfectly to size and is a really cool lightweight material that super quick dries. After working out, the shorts aren't even wet from sweat after about 10 minutes of cooling down. They also must have an anti odor feature because they smell perfect after working out too. Super job here, Columbia!

Purchased these shorts for working outside/exercise/summer wear. I work on a farm inside a greenhouse and there is a lot of water, I am constantly getting wet. These shorts dry out quickly and are comfortable to wear. I'm 6'1'' 175lb the M size 8 inseam is a bit tight for me, I probably would have ordered L next go around. My only complaint with these shorts is there are no pockets, apart from a small zipper pocket on the back of the shorts which I have used a total of 0 times. If I put my phone or a key or anything in that area (1) it would be uncomfortable and (2) I'd probably sit on it and crush it. My guess is the shorts were designed for running/exercise only....

I live in Florida. The humidity is unbearable during the summer. The Columbia Zero products make a big difference. They have become my daily attire.

Great Shorts but I wish Columbia had used a boxer lining instead of jockey type liners. It did not function well in humid weather.

Rated 3 out of 5 by WalkAndTalk Ok but no pockets
I ordered two pair. One was the shorter "6" and the other "8" was the longer. The fit should have been the same but wasn't. The shorter fit much tighter in the waist and rear. I would have returned the shorter pair except that I had already cut out the tags. Additionally, the shorts do not have front pockets; something that I wish they did.

Needs reflectivity in the back and larger reflective logo on the front. Zip close pocket should be larger. The fit is too large through the legs. Columbia should go tagless in all its products. I would have liked to buy this in a white color, or perhaps hyper blue, red, or light grey.
If Columbia would offer Omni freeze zero briefs, boxers, and compression shorts that would be great.

I just finished up a 5 mile run in these. I do miss having a side pocket as walk from the car looking for a place for my phone. The rear pocket is literally as deep as an ID card and a little wider so you can get it jammed in there. Didn't even notice my ID was back there the entire run. I didn't use the inside flap pocket as I usually cut them out. The liner is amazing and I wish I could get underwear this comfortable.
My only concern that dropped these to the 4 stars on the function is there is a slight bunching in the crotch from running. I usually wear New Balance shorts through the military that are 7" versus these being 6" and there is less on the NB shorts. Then bringing my leg up in the front like knee raises there is some drag with the shorts. Maybe that will go away in time as I wear them more.
Otherwise, I'm happy with these shorts and will wear them quite often.
