The only Arcteryx pack I have ever used was one I carried for several years on the job - fairly heavy use, sometimes with quite heavy loads. It was insanely comfortable and useful - a really good tool. I was by the office the other day and noted that my successor is still using the same pack regularly. It is now about fifteen years old....

If the only downside is cost, swallow hard,live on beans for awhile, and come up with the dough. Every time I did that I was glad.
