I see a lot of packs made with 500D and not 1000D. I'm guessing it's due to 500D's tighter weave and lighter weight?
Is something like the MH ThruWay 50 (http://www.mountainhardwear.com/ThruWay%E2%84%A2-50/OU4536,default,pd.html) too lightweight? 100D ripstop ... will just get shredded? I don't know exactly how much abuse they take since I'm just getting in, but I definitely don't want to have it die in the field ... :)
Thanks for thoughts!
