Hi all, I'm going on a 6 week long trip and I would like to minimize the amount of gear I want to take as I'm allowed one suitcase and two cary ons. I'm looking for a bag that I can take through airports but at the same time am able to take it snowshoeing on a 10 km hike that includes two bodies, 4 to 5 lenses, filters, batteries, my tripod, and some hiking equipment as well. I've looked at the Manfrotto Velcoe V bag and the lowepro flipside.

What are your recommendation.

p.s. my budget is $150-$200 USD
