User Review: Osprey Switch 14
Price Paid: $120
This is the most versatile pack I've ever owned. The stiff side walls and wrap around compression straps allow it to compress snugly enough to run with comfortably, and allow it to expand enough to fit all the gear I need for long day back country skiing, or even an overnight.
As long as you're not one of those guys that bring along 100lbs of the lightest gear made, it is big enough for most stuff, and small enough to make you think about what you really need.
The compression straps also allow it to strap things on and carry them well. It can carry a full 60m rope easily this way. I've even had occasion to strap on a full bicycle for a hand over hand on a cable. By far this is my go to pack for almost everything.
