Gregory Zulu 55

Outland USA says:
Dialed for alpine overnights and long summer weekends, the agile, ventilated Zulu 55 is truly a weekender's dream - especially if your weekend dreams involve moving fast in fun terrain. 55 liters is plenty of space for a luxurious three-day warm-weather escape or a night of winter camping, but with Free Float suspension breathing and moving with you, it feels like you're out for an afternoon.
