Khaki Curvy
Plan your run so that you hug the walls during the curvy part - hug the right wall as you enter the curvy. While you are in the air after jumping to clear the gap following the curvy, crouch in midair and remain crouched until the end of the entire jump. If you have enough speed you will powerslide right over the striped barriers. You may want to read this information regarding the powerslide.
