Replying to I need sine advice on a good backpack for skiing

So im in need of a backpack for this season and i have been looking at the Dakine Heli pack The things the pack needs to have is sine roon for a spare lenses(goggles), maybe a pair of mitts, and a snack or two, it doesnt need to be a camelback and a chest and waist strap is neccesery :). So does anyone have either sine experience with this pack or suggest something else that would be great! :) Thanks ns
