Michel Rouen Golf Trousers

The two cuts here are bought for opposite halves of the year. The fleece-lined winter pair is for a wet, cold round: the lining runs through the seat and thigh where a walking round makes you cold, and the face shrugs off dew at eight in the morning. It is warm, and it is slow to dry once it is properly soaked. That is the trade and it is better known before you order than after. The dress trouser is the one that goes from a round to a table: stretch woven, flat front, and a zip pocket so that a key and a phone are not loose in a back pocket for four hours of walking.

Waist-by-leg sizing is the thing to get right, and it is simpler than it looks. The first number is your waist, taken level and snug at the point your trousers actually sit rather than at your navel. The second is the inseam, and the fastest way to find yours is to lay a pair you already like flat and measure from the crotch seam to the hem. Both cuts run 30 to 42 in the waist, and the leg runs 30, 32 and 34. Eleven colourways between them, and prices from $43.65 to $49.95, the top of the range on this site.
