Common questions
No — not on most airlines. Bear spray canisters (225–370ml) are too large and under too much pressure. Ship it to your destination or buy/rent at a park outfitter.
Similar rules apply, but bear spray is larger and under higher pressure, making it prohibited even in checked bags where small personal pepper spray (≤118ml) might be allowed in the US.
Buy it on arrival at an outdoor equipment shop or park visitor centre. In popular bear country (Yellowstone, Banff, Glacier), rental is available at trailheads.
