100% cotton. Brushed flannel fabric. Full button fastening. Chest pocket. Buttoned cuffs. Curved hem with air vents. Regular fit. Although reputed more for their easy breezy summer shirting, turns out Original Madras are pretty good at wintry wares too, as can be seen by this Straight Collar Long Sleeved Shirt. Between that tough brushed flannel fabric and and that webbed split seam, this one is primes for hoarding heat whilst looking cool ‘n’ collected. Could do far worse than this one.
