You could go crazy with a backpack purchase -- there are some giant models that would fit a military bunker's worth of stuff. But what if you need something substantial that's also appropriate for carting your laptop into the office each week?
Uncrate has teamed up with Topo Designs for a lightweight day backpack ($US89). If you suffer from that awful curse where you somehow lose things inside your bag, you'll like this one for its bright orange lining. It comes with a government-issue knife with a two and a half inch blade, and it's got moisture wicking straps, so your back won't be soaked in sweat whether you're commuting to work or hiking off in the wilderness.
