I usually wear a 10 long in most of the pants at 5.11.(For comparison I wear a 30x32 in women’s Levi jeans)
However, I got these in my normal 10 long and I don’t know if a 12 will even be big enough. They fit extremely well in my waist and then from the knee down, but the stitching or style of pockets on the sides make it extremely tight through the mid thigh. I’m hoping a 12 will fit better. The pants are extremely light and comfortable. I am in law enforcement and these will be perfect for the hot summer days as long as I can get the right fit all around... I’m going to return and hopefully get a 12 to fit! Will update after!
