I keep my ground coffee in an OXO too!My wife bought a few of these Oxo Pop containers for rice, barley etc...
POP Container - Big Square Medium (4.4 Qt.) https://share.google/ySXYkHY4S2kXWJ6gj
I'm going to ask her to get a large one for the beach....the stainless canisters are ok if you're making coffee every day. 2 weeks with the clip on the bag is ok. 2 months probably isn't.
Ours is a smaller model though I think.
