Duvet (opt)
A down or synthetic duvet jacket can be very cosy, but they are expensive if you don't have one already and also quite heavy to carry. You will certainly be able to manage without one, but if you have space in your luggage and have one already, bring it with you and judge whether you want to use it when you've seen what the weather is likely to do during your ascent.
