Comfortable, fair price. Good product

### ⭐⭐⭐⭐⭐ Great product
*by A***R on 22 November 2019*

Good fit waistband doesn't fold over like others i have had and has a working fly

### ⭐⭐⭐⭐ Remove entire label for comfort
*by R***Y on 22 September 2019*

What is it about clothes labels - designed to cause maximum discomfort. Label designed must be masochists. As with all clothes first thing is cut off all labels. With this item also need to remove the whole label as the stub on the waistband is otherwise like a blade cutting into you. Otherwise nice product
