We absolutely LOVE this pack! The removable bivy pad is SO convenient, we use it instead of packing sleeping pads! Also, as always, Dana's unrivaled comfort is one of the main reasons both my wife AND I have this pack. It is the PERFECT weekend pack, and serves well through all four seasons! If you are looking for a pack that encourages you to get out in all kinds of weather, look no further! They should've named it "Jack of all Trades", we've taken ours boarding in the winter, day and weekend hikinig in the summer, and backcountry trekking in the spring and fall. It gets an A+ from us!
