Women's Cross-Body Bags Leather Large/Medium Twist Lock Cross Body Messenger Bag Turnlock Shoulder Bag

Does the main compartment have a zip closure?

Can anyone help with the colours. The khaki looks more tan and the light brown looks orange/brown? Do I go on the name or the colour in the photo?

How long is the strap on the large bag please?

What material is the strap made of. It looks like canvas
