I am 6’2” and originally ordered a large based on other reviews. Mumbojumbo too loose at the waist and pant legs were too long. Returned and got a medium, perfect size!Trust your regular size on this, if you normally wear medium then order medium.I'm 5'10 and about a 33 waist so technically I should have gotten the large but I went with the medium instead. They're a bit more snug than I'd like but not unbearable. The cuff falls right at my ankle which is nice but i think at my size a large would overall be a better fit, but that's my fault, I didn't pay attention.In any case I really love what they did with these pants. They're a nice soft, very thick, synthetic material. But really the brilliance of these pants is that they HAVE POCKETS. I've been looking forever for sweatpants with a zippered pocket and they're so rare. Not only do these sweats have two zippered pockets on each leg, they also have a pocket in the back AND a pocket at each side. Holy cow, 5 pockets, two of them with zippers!The best part is that if you wear these to the gym your phone and keys will be safe because the zippered pockets run along the lower outside of the pants. Brilliant, really, I'm not being sarcastic. If you've worked out in a gym you know how sweet these pants are. The drawstring waist helps a lot if you've loaded up the pockets with a wallet, keys and a phone. They thought of everything. I think a team of NASA scientists made these sweatpants.I am a athletic build. 6'2 , 185/188 ish lbs. 32 waist. Medium fits me great, waist area is SLIGHTLY loose, nothing to get mad or worried about though, like I said its a very minuscule amount. The large( which I was almost about to get before I read some guys comment on here with almost the same stats as me) would have been worse. These pants are not short, great for people with longer legs, but also not baggy. The material is soft, though seems sturdy enough that it will be able to go through a series of washes, and physical activity before tearing. Seriously, I will be buying more pants from these guys!I brought the camo color, and black color. Same review for both!5'11" 170lbs and a medium is borderline too big. Waist is pretty big and legs are definitely not a "slim jogger". That said, the material is a good balance between cotton and synthetic. Looks good. Just wish the legs were a bit more snug. The white drawstring is horrible though. It's the cheapest piece of string ever, plan to replace it with something more sturdy, and black, you know, like everything else on the pant. 4 stars. If you're slim id say order a size down unless you want a oversized look.I hate most sweatpants because the pockets they have are not secure for my wallet/phone. This cargo style allows me to enjoy the comfort of sweatpants with the pocket security of cargo pants. These are by far my favorite pair of sweatpants but my issue with them, and the reason I docked it by one star is that one of the buttons for the pockets popped off when I tried to open the pocket. This was about the second or third time I wore them. I tried reattaching it but it doesn't work. I still wear them because they are very comfortable. I'm not sure how to contact the seller so I'm hoping they read this and offer a replacement. Attached is a picture of the pocket.I will probably buy another pair; these pants are easy to like, a highly functional garment that blends in at the gym or on the streets seamlessly. A solid color would fit in on casual Fridays at work. CAVEAT: I followed the size chart with my first order and picked large, and it fit loosely around the waist. The medium fits perfectly. For a point of reference, I wear a 30-inch waist in khakis (Amazon's line) and blue jeans. The company's sizing-suggestion chart may not be correct (?). So, I waited an extra day and am still 100% satisfied.Awesome pants, the only exception I see is the drawstring is kinda thin. If they’d come with a denser waist drawstring then it’d be more convenient. Good pants besides that!Great for lounging or workouts...
