I’m slim athletic 5’9 178 pounds. I buy small sizes. They fit Snug but not uncomfortable. The medium may fit also but I’m afraid to waste my money if even they’re a little bit loose. Overall I’m happyNice breathable fabric, gives you great support in the right places, and these shorts to me, actually seems to energize me when I workout. Especially leg day!Bought these to use as boxer briefs and for that purpose they work wonderfully. They don't ride up during the day and they quality is great for the price. I prefer them over the more expensive nike pro combat shortsThey are what the picture shows I've washed them and still holds there shape and colorLike the fit. Very comfortable. Doesn't slip, bind, or sag. Not tight in one area or loose in another. Can wear all day & not have a problem with comfort. Breathable material.Update: I have to add a star for these. After using and washing these a few times the material did shrink a bit and tighten up. So now they do have a little compression and actually fit really well. I judged them before washing them and they do change quite a bit, so don't judge them right out of the package. I would actually recommend these now.Original review:These are definitely larger than I expected. Higher waist, longer than a normal pair, and quite stretchy. They work ok, I'm just using them for rowing so I don't need a lot of support there, but if you want to wear them for running, I would definitely get a size or two down from what the size guide says. I probably won't buy this brand as I was looking for a little more compression on the legs, but they work well enough to keep using and not send back.These are priced right and do exactly what I needed, which is essentially “anti-chaffing” for my inner thighs while running.These work great and have so far held up to use and washing. Elastic remains strong and not stretched out.I will be buying more.Considering you can by 9 pairs of these for the price of one pair CW-X pair of tights, they're great. Comfortable and good fit. Of course not as much support as tights like CW-XUse these bad boys when conquering peasents In any physical activity of my choosing .Chicks dig them 5/5got what I ordered and does the job.
