I bought these of a user on Superfuture over 4 years ago, they were solid white at the time so I dyed them a very dark grey using a combination of Dylon dyes. They were never worn by me (they were balls tight when I got them) and show no signs of wear from the previous owner. There is, however, a pink line under the back right pocket, this is from the sun hitting them daily, as they sat folded in closet for years. I'm not sure what the material is - there is no care tag on these - but they feel like a medium-light weight cotton. Don't be afraid to pm me with any questions of offers. Thanks for looking! measurements - BiG style Waist - 30" Inseam - 31.5" Front Rise - !0" Back Rise - 12" Thigh - 10" Knee - 7" Hem - 6.5"
