We have a spare bedroom that's officially named the "Gear room" Shelves with rubbermaid tubs of varying sizes for hammocks, underquilts, sleeping bags, and all various and sundry. Pegboard on another wall, bin boxes for small stuff mounted on another wall, and two chests of drawers for anything else.
Its not "put away for winter" so much as its just put away where it goes. Winter is outdoors season down here. Its the worst part of summer that I give up and don't go out at all.
