Re: Arcteryx Blade 30 Pack
Arcteryx makes some very decent gear, but..
Whatcha gonna do with that bookbag/backpack? No waistbelt, not much of a suspension system. Save your money and try the local goodwill for a $5 used jansport or northface book bag/daypack.
Unless the pack has stays or a molded plastic backframe, it won't carry much weight. Looks like a great range bag or organizer, but not much for hiking with gear of any weight.
You can find tons of adaptable gear very cheap at resale shops, or on Ebay. I got a Blackhawk patrol bag for $100 new w/drinking bladder and tube a few years back on Ebay. Probably find even better deals there these days.
Gregory, Mountainsmith, Lowe are all integral frame backpacks I've used with good result. I like the medium ALICE pack with straps as a daypack for hunting. Goes good under a poncho when it rains. Might want to look at mountaineering day packs for best versatility.
The Arcteryx shown is I'm sure nice gear, but what will you carry in it?
