Hi Seb, my bikes remain outside all year round.I have had a Oxford STORMEX cover on bikes now for 3 years.It serves me well.Fully insulated fleece lining,openings & pocket for chain & padlock , buckle with strap for closing low down.I chose the largest cover as my previous bike was Triumph 1050GT(very long-massive panniers).It's a bit baggy for CR without full luggage but is still fully waterproof although faded by the sun(see snap). Hope this helps you.Cheers Ali.
