Horrible. I bought one at a garage sale just because I thought it looked interesting. I can't figure out why anyone would willingly carry a 30 year old backpack when there are hundreds or even thousands of backpacks on the market today which are much lighter, more comfortable, and better designed. I can't even say it's because it's cheap, because for what I see them selling for, you can get a decent backpack for about the same price. I think some people equate weight with durability, but for the weight of one of those packs, you could carry another spare pack inside your modern day pack and still come out ahead.
