We bought these bags (3 of them) here last time and absolutely love them. They are super lightweight. 7.3 pounds and very durable. They are made from a rip stop nylon and well made smooth zippers. No getting stuck every few inches because of cheap plastic zipper teeth. Highly recommend. Sent this link to a few family members and friends that commented on how great the bags are and what a good price they are at right now. You won’t find this quality bag/brand for less than $100 for their size etc.
