Deuter Guide Tour 45+

This smart, simple pack will carry all your essentials (including the wine) while still offering useful features like a carry system for skis and snowboards, two ice-tool holders, a detachable hip belt, and a snow skirt. It's roomier than you'd expect for a 45-liter bag, and the top pops up for an extra 10 liters of space when it comes time to shed and stash layers. [$189; deuter.com]
