I got a medium like I wear in all running shorts, but these are SOOO tight. I don't even know if I could do a squat in them.

Really Pretty. I'm a Medium in everything and I was Swimming in this, So I'd say if you want to get it, get one size down than your normaly would.

I usually wear a men's medium waist for athletic shorts (Umbro, Adidas, Nike) and they usually fall just above my knee lengthwise.  Just to be safe I ordered a large.  The shorts barely made it past the midpoint of my thigh and my legs aren't overly long.  The waist fits well but if you're looking for a pair of workout shorts, I'd skip these unless you like to show a lot of leg.

Bought 3 pairs different colors after ordering one in medium one in small. I am 5'10" 153lbs with long legs and I needed some cheapo running shorts that I could wear around the house as well. Not much difference in size between medium and small except wasitband and liner. I tuck my shirt in when I run and since no drawstring I returned mediums and ordered smalls for the tighter band. They are cheap, dry quickly and Ive machine washed and handwashed them as well. Easy to handwash and flip inside out to dry in sun. Dries in an hour in the California Sun. Socially acceptable? Maybe not so much, but cheap and comfortable for sure. It would be a stretch to rock these at my gym even though im already the only dude who works out in running shorts. Its my F.U. to the companies who make an ultra thin, super short bathing suit, call it a running short and sell them for 45 dollars and up. I'd run naked if it didn't land me in Jail.

I really like these shorts. I'm not sure if the minerals in it help or not but they are comfortable to run in so worth getting regardless. Plus they look great :)

I'll keep them in medium (I'm a 32 waist)
For the next time I'll order large to see the difference
Overall it delivers for its price

I'm a short female (5.1) and I have a hard time finding running shorts that are the right length.  I also like the snug fit - they don't gape open when I do floor exercises.  I ran in mine this morning and they were very breathable and I did not over heat.  Although I agree with the built-in-underwear comment - it definitely should have been in the description - I still like the shorts  a lot.  I'm buying them in every color.

I am a bald and barefoot 5'9 and quarter,  in between 167 and 170 lbs.  I wear anything between 30 (Lucky Jeans) and 32 (Dockers).  I got the XL and it fits great.  It reminds me of the volleyball shorts that I wore in college more than 20 years ago.  Back then shorts were shorts.

The only reason I am rating at 4 instead of 5 is that pockets are small.  My wallet fell out when I sat in the car.  Luckily, door was closed when it fell out.

All my other athletic shorts are so short.  I they were still available in the other colors,  I would by them all.

this pant rides down while I jog, the size is perfect though I got in a medium and I'm 5,9 152lbs and my hips are a 42..very stretchy. the material isn't good for sweat though. it sticks to your skin.

I've worn these shorts twice after purchasing them, and I enjoy them so far. They are comfortable (I bought XS and thought they'd be a little too small, but they fit nicely), and nice to run in. At first I thought the compression shorts underneath would make the shorts themselves a little heavy/too hot to wear, but they aren't bad. I also like that it provides coverage but are breezy at the same time, because I like to stretch immediately after running. The pockets are nice and big, large enough to hold phones, keys, etc, and ther is also a very small, discreet pocket on the inside of the shorts as well. Overall, I really recommend these shorts and would like to buy another pair, because I don't want to always wash them and wear them out.

I am 5'6 and the small size is a good fit. When on, the shorts are just above the knee. They are very comfortable and are great for the gym and running.

The medium fits perfect over shorts and a t-shirt. I'm 5-9, 155 lbs, athletic build.  Would be too small if wearing over full clothing.

Under Armour's 5" Mid shorts are my favorite shorts to run in. The first pair of UA shorts I got were 3". I like them, but they're pretty short (not so short that everyone can see my business but short enough to where I prefer wearing them when working out at home than at the gym or running). The 5" shorts offer full coverage (and then some) while still keeping you cool on hot summer runs and giving you that lightweight feeling (which I like to feel when running). I can usually wear them for two runs before I need to wash them, but since I have three pairs, I don't need to.

The quality of these shorts is excellent. I have another pair that I've been running in for about 3-4 months, and they're still in great condition. They're stretchy and moisture-wicking, making runs and workouts more comfortable. The elastic waist band can be uncomfortable sometimes. If it's too tight around my lower back while running, I'll roll it down and it's fine. Most of the time, it doesn't really bother me.

When choosing a size, keep in mind that these are compression fit. For size reference, I'm 5'2" and 103 lbs with a 26-inch waist and 37-38" hips. The medium fits me perfectly (not too tight or too loose.) Pics are from after wearing the shorts for a color run. I washed the shorts within 2 hours of running and the color came out fine :)

Bought these to try, since the price at the time was lower than most of my other running shorts. I have several types of Asics apparel, and I typically wear small in their shirts and pants/tights, but went with the medium in these as I wanted a looser fit and they fit fine. Definitely more polyester feeling than other shorts I own. Doesn't have any pockets, but does come with a liner. Would buy again at the right price...
