The Bearikade Expedition worked really well for my JMT thru.
I stored my sleeping bag and cloths in the bottom of an Osprey Volt with the Bearikade sitting upright on top of that. Sleeping pad, stove, and other small gear fit around the bearikade with tent lashed to the bottom.
The zipper pocket under the hood of the pack was the perfect place to store a coin to open the canister. It allowed me to stop during the day for lunch and access my food without removing the bearikade from the pack.
Because of its ease of use, I could easily understand someone wanting to use a Bearikade on the AT or other places to make is really simple to not only keep your food safe from bears without worrying about hanging your food but just keeping it safe from critters. Perhaps the only reason I didn't hang on to the Bearikade I bought for the trip was because most my camping is in GSMNP where every campsite has bear cables and I don't have to worry about figuring out how to hang food to keep it safe.
