7's button fly are more relaxed than the 7's with zippers. Paper Denim Cloth are also quite slim fitting. Chip and Pepper "big pickle" style is very relaxed.
My brothers has Sevens, True Religions, PDC, Antiks, and more hip labels that I'm not cool enough to know about. The only ones I've ever tried was a pair of his True Relgions (Joeys with flap pockets)... they were too big on me but I liked how they were cut looser then the womens. I was surprised the rise was as low as the women's though.
