Technical flat drawn to scale from the size chart.
SD-108
SDA's relaxed taper: comfortable through the seat, narrowing cleanly below the knee.
For a 32″ waist (our default: enter yours). Size 31’s waistband measures 32¼″, ¼″ over your waist. That’s within normal measuring variation, so it should sit right at your waist once it’s broken in.
