Comfortable and light

I love this shirt. It is very comfortable, practical and very very light too. I take it to all my trips without a doubt. If you are accustomed to the cotton fabric it may seem a little strange at first, but it is very comfortable (I am quite sensitive to a lot of fabrics). Although personally, I like the cut of suspenders more. It comes pretty packaged, which I do not like much for the waste, but most cardboard boxes that can be recycled.

The photo shows short sleeves and it has a different ref number to the same long sleeve one. Is the description wrong and should read ‘short sleeve? I am wanting short sleeves

Answer of Vlad
