I like this pack so much I bought three of them. No lie. First I bought one for my wife (we enjoy strenuous dayhikes in the Rockies). I borrowed it to use on a dayhike with me brother and he envied it so much that we bought him one for Christmas.
I found myself using my wife's bag so much that i just bought one for myself.
It's tough, it's well thought out, and it's just the right size. Perfect for carrying trekking poles (when not being used), fishing rods, or water bottles. Bladder sleeve also if you prefer that route.The waistbelt serves no functional purpose though, so I cut it off. No biggie.
I own some very high end overnight backpacks, but I love this little gem from Mountainsmith for day trips.
I'm a picky SOB and I have thousands invested in backpacking gear (it's about my only serious pastime these days, so I willingly throw money at it), but this relatively cheap pack has earned a prominent place in my gear collection.
