ขอบคุณที่แจ้งให้ทราบ
sold my GST as well and just bought the cerf. It was so heavy and started to slouch a lot. I've read the cerf will slouch also, but since it's not as tall, I don't think it will look as bad. Also, the GST is so deep and hard to see inside, it was always hard to find stuff inside the bag.
