Great bag, Cheaper Materials
I just did a wall with a friend who has an older version of this bag. The differences in materials were quite apparent. The top closure system is now cordura, which is no where near as abrasion proof as the vinyl one on the older design. Other changes were apparent, but did not affect the bag in use. I feel that I got the value I expected, but would have been happier with a more durable closure fabric. Mine suffered a hole in it in just one wall, all be it a seven day wall with multiple very hard hauls. The NA wall is very hard on haul bags. I would buy this again.
The back pack system is very good on this bag. We carried 85 lb loads down without difficulty.
