Most definitely!
Oxygen is the enemy of hops, but temperature is equally important. I have a pound bag that I cut one corner off of and "seal" with tape after every use and store in the freezer inside of 3 layers of freezer baggies. While this isn't ideal, every time I open my bag of hops, it still smells fresh and aromatic. You could play with fire like I do, but your hops will last longer and stay fresher either flushed with CO2, or vacuum sealed. Only reason why I haven't invested in a vacuum sealer is because my hops are strictly used for bittering, and I don't have a use for a vacuum sealer in my daily life. The day I buy flavor/aroma hops by the pound is the day I buy a vacuum sealer.
