A bit of BAM genius we hope you\'ll agree, this overshirt lines a soft flannel check shirt with our cosy 285gsm medium sweat. So what you get is something lightweight but warm, casual but wearable anywhere, and comfortable beyond belief. And there\'s bamboo in both layers (along with organic cotton), so the overshirt is immensely soft yet breathable, temperature regulating, absorbent and odour inhibiting. Styled with top pocket, buttoned cuffs and shaped hem.. . Layer up or wear next to your skin. Woven flannel outer & fleecy brushed inner. Inner sweat lining composition: 67% Bamboo Viscose, 27% Organic Cotton, 6% Elastane. Ideal for sensitive and allergy-prone skin
