These are just cheap shorts with dry fit underpants sewn in to bump up the price. Garbage. These shorts are already large so you should probably go 1 size down for a regular size and 2 sizes down if you want them a little tight. I say slightly tight because they are never tight, they are just too loose. Fit They're not form fitting, can't accentuate enough, they're just loose shorts with another pair of slightly less loose shorts sewn in. I would almost recommend downsizing by 2 but honestly it's better to buy another brand. The briefs are made of "Dry Fit" fabric, but in reality they are so loose that you probably won't even put them on. Get all the benefits of a dry fit except the fact that it doesn't absorb sweat or weigh you down. You'll probably want to wear underwear underneath just to sit up because briefs aren't tight fitting and will likely look the same as regular gym shorts. Case I've read a few reviews and after trying it I'm really not sure if it's a phone case. I think it's actually for loose dollar bills because that's all you put in here that won't fall out. The pocket is too big, loose and stretchy for small phones and on the other end of the spectrum too small and stretchy for big phones. I'm not exactly sure what size phone this phone was made for, but it's not your phone as it will fall out. Training: I didn't even try because walking on the carpet without shoes was enough to make the shorts fall off. out. I couldn't imagine walking, running, or even lifting weights in these shorts without my phone being my number one concern. As a result, you're probably spending more time worrying about your shorts falling off or your phone falling out than concentrating on your routine.
