Charles Tyrwhitt Men's Regular Fit Pure Wool Birdseye Stretch Trousers - 3432 - Grey - Available at M&S
Designed with a reimagined birdseye weave, these suit trousers by Charles Tyrwhitt are a refined choice. They're cut in a traditional regular fit from breathable wool, with natural stretch for easy movement. A curved waistband gives plenty of room to move while a half-lining to the knee helps keep wrinkles at bay.
