I bought these wanting something that didn't shift, ride up, give me a wedgie and bulk up when i put my jeans on. These took care of all of that. they stay put on my legs, and are true to fit and comform to my body. these do feel like a second skin after day one. the leg bands are a little thick, and are visiable through your jeans when you sit, but hey, i don't care, it must serve a purpose. the waist band does roll, but again it must serve a purpose. Also, I don't have any "crack" showing when i bend over. I'm very pleased, and i would buy more. i have bought 2 packs seperately. These are shorter in the leg,(5inch) there are 9 inch seamed ones too... both are great. I just wish they had more colors/patterns to choose from. These are hands down the best, most comfortable true fit underwear with everything i've ever wanted. BTW, there is no fly opening with these, but don't let that steer you away... who uses that feature anyway? You'll remain where you want to without falling out of the pouch.
update almost a year later(10 months) and they've held up to dozens of washes and drying. they have also maintained the same stretch and conforming fit since day one. the color has not faded. I don't sweat that much anymore when it's hot out, so no swamp in front or back. the moisture wicking does help a lot. i'm so satisfyed with these that i just bought more. it strange to give a review on underwear, and i've been through so many brands and styles over the last 30 years plus, but these do deserve a review.
