Sleeping Bags for Drakensburg

Hi Arno

Quick question here, I have quite a few hikes lined up for this winter. All of them sleeping in huts. I have the Sea to Summit Liner already

Thinking of buying this sleeping bag next week as it is down and very light at 595g.

Whatcha think? Should be warm enough indoors using both bags? Many thanx
