The Original 7" Compression Shorts were Awesome!

UA's original 7" compression shorts couldn't be beat! But the newest ones with the large waist band are too uncomfortable for me. The old version which I have owned 20 pairs weren't as thin and the waist band was much smaller, came higher up and were more comfortable. My friends and I used them not only for running but under dress clothes. They were way more comfortable than Spanx and did the job just as well. Under black evening gowns, dress pants and cocktail dresses they worked great, however I would have liked to have seen them in Nude as well. Bring back the old design!

Waist too big

I was looking for a tight compression short but the waist was loose and longer than I expected. I'm 5'7, 165 lbs and bought a large.

too big in the waist

I did the True Fit test and it came up with Large. Okay. I am 5'11" and 165#. I also bought a pair of running capris in Large. The capris are fine (just a smidge too loose) in Large, but these compression shorts, which I plan to wear under running shorts (because they are always too short for my taste), are huge in the waist. There is a large gap between the waistband and my back. I can stick my finger in the gap without pulling the waistband. They are certainly going back in exchange for a Medium. I like the feel and color of the shorts, so I am hoping a Medium will work.

7" compression shorts

The are awesome! They are so comfortable and are true to size. I tell everyone about these shorts. I just wish they came in nude!

Very nice for running!

I was looking for a good longer pair of tight shorts to wear under my loose fit shorts so I didn't feel naked when I am running on the treadmill and these are perfect! I like the fact that they don't run up on me and they stay in place nicely. Will wear them all the time!
