These trouser are the slimmest Snickers make. The dropdown sizing shows “upto” as the maximum waist size. Some customers find that going up an extra size gives a better fit but this is a personal choice. The label inside the trousers show a different size as Snickers use the same tags as they use in the loose fitting 3 series. Please do not think you’ve been sent the wrong size. Our size chart is accurate for the 6 series range.
