Frequently Asked Questions about Mens Shirt Long Sleeve
What is an Easy Iron shirt?
An Easy Iron shirt is made with fabrics (bamboo + polyester) that wrinkle much less than pure cotton. After washing, it needs little or no ironing to look impeccable — ideal for work and travel.
Is cotton flannel suitable for winter?
Yes. 100% cotton flannel is one of the warmest fabrics for winter shirts. The fabric’s brushing creates an air layer that naturally retains body heat without the weight of thicker fabrics.
What is a button down collar?
The button down collar has small buttons at the tips that fasten it to the shirt. Classic American style, suitable for both casual wear and with a tie in business casual settings.
What sizes do the shirts come in?
Available from M to 5XL depending on the model. Regular fit. If you are between two sizes, we recommend the larger one.
Is there free shipping?
Yes. Free shipping in the Peninsula from €30. Orders before 18:00 arrive the next business day.
