RLX Cypress Tech Golf Trousers Foster Blue AW14. RLX Ralph Lauren Golf Trousers for Autumn/ Winter 2014. We love this brand new foster blue colour way of the popular Cypress golf trousers from the latest RLX golf collection, perfect to match in with tops from the latest range. The Cypress golf pants feature a lightweight stretch fabric which is incredibly comfortable to wear, whilst two front & two rear pockets feature.
