I purchased skybag a year ago .The cost was little high around 1999.The quality of the bag was not soo good as compared to the material of the bag .The material they used was hard .I took a printed bag and the print of the bag got vanshied within about three to four months .The zip movement were average but sometimes some of the thread came out and got stucked in the zip .
The things I liked about the sky bag was that the size was pretty good and company have made many useful and secret pockets inside the bag.
Rest the skybags are average to buy .
