The Trek Women’s Long Sleeve Sport Shirt by Double RL Ralph Lauren is crafted from a sturdy wool-cotton blend inspired by classic American workshirts from the 1920s and 1930s. The yarn-dyed plaid twill fabric gives it a rich, authentic texture and vintage character, while the two buttoned chest pockets add both function and timeless utility. Finished with distinctive chain stitching and a runoff thread detail, this shirt reflects Double RL’s dedication to traditional craftsmanship and rugged authenticity.
