Has an "all weather" cover that comes out and folds over the top of the pack to keep it waterproof. Never needed to use it, found that even if it's snowing hard the inside of the pack stays nice and dry.
me? its not, if its like that we wont make one because you cant. we either wait till it gets heavy or make it when its heavy enoth, we made most at the end of the season
food and drink cause, 1) cause mt food is amazing, but way over priced 2) cause i dont stop i ski from 9-4 and eat lunch on the lift, and then ill throw my shell in it if its a blue bird day
not sure if there is anything there right now but you can usually get really nice things off of www.backcountry.com then go to the outlet store there, they usually have hiking backpacks that are waterproof, they get the job done
i use the dakine mule i belive, its their bag meant for water, so it has a removeable resovior, but it works and it isnt big so it doesnt affect my skiing.
