Cuben Fiber .7 oz sewn to Cordura 1000 denier nylon with 4 rows of straight stitch and to itself with flat felled and glued seam. Shock loaded to failure (body weight plus a jump). Notice the tie out webs were not the failure point. Also that a flat felled seam with only 2 rows of stitching proved stronger than a simple lap felled seam with 4 rows of stitches. The glued seam did even better than that.
