it's a bit heavy, but great for long trips.
i'd like a daypack, especially for snowshoeing and skiing.

dp: how do you like your
granite gear vapor trail ?
I like it fine, I feel it's a great product for me. The price isn't too steep and I like how comfortable it is to wear and carry.
Downside is the packing. I'm all for smart packing and knowing where things are, but sometimes it's just inconvenient to have to unpack to reach certain things. So sometimes without a bottom compartment zipper it's inconvenient at times.
