Our traditional Stripe Flannel Irish Collarless Grandad shirt is THE Classic men’s Grandfather shirt made from soft cotton flannelette. The fabric has been expertly brushed for softness and warmth, giving it the perfect balance of softness and durability. We prefer the honest simplicity of our own grandfather shirts – the way they were meant to be. A shirt that feels like you’ve been wearing it for years; what’s more it’s made so you can.
